honeywell thermostat lcd display not working manufacturer

Based on my experience and research, I decided to compile a list of common go-to fixes that you should try if you find that your Honeywell Device is not working as it should.

So, how do you fix the no-display issue on your Honeywell Thermostat even after you have replaced the batteries? First, check the power, wiring, and reset the thermostat.

Re-insert the batteries in the correct orientation; once you have inserted them successfully, your thermostat should start displaying information after a brief pause.

Keep in mind that while sometimes the thermostat issues can be fixed, in other cases, you may want to consider replacing your thermostat or perhaps upgrading to a newer version.

Ensure proper maintenance of the device, as Honeywell’s Limited Warranty does not cover products that have been damaged due to negligence, such as failure to follow a regular cleaning schedule.

Your thermostat display could refuse to work if you don’t close the control door completely. If it’s not the access door, you’ll need to inspect the position of the breaker switch, inspect the thermostat configuration and check for sensor issues.

We assume that you’ve connected your thermostat to your smartphone application via WiFi and if it is still connected while the display is not working, it means that you have full control over it.

Regardless of if it’s only the display or the entire thermostat is not working, here are a few steps to apply that will definitely resolve any problems related to

When ready, make sure that the internal hardware that you’ve cleaned is DRY before you turn on the thermostat. Lastly, test and check if the display will turn on.

Once you turn on the thermostat the display should light up and provide you with visuals of the initial setup configuration. If not, continue with the next step.

It is possible that the mercury switch is not reading the temperature you applied correctly. This can cause your system to power offandonover and over again.

In most cases, these symptoms are related to the temperature sensorfault, which will definitely prevent the display controls or disable the visual entirely.

If both values do not align perfectly (there should be 1-2 degrees alloweness) then you’ve got a sensor issue, which is not that expensive to be replaced.

Next, we’ll review cases in which people report that they cannot adjust the brightness of their display which if lowered to the minimum can make the impression of a non-working display.

Turn OFF your thermostat, then locate the circuit breaker responsible for the HVAC system and turn it OFF as well. Wait for about 1 minute and put it back ON.

Once you’re done with these steps, restart your thermostat and check if the display will work. If it doesn’t, well, your display might just be broken, and you’ll need a replacement.

To fix a non-working display on the Honeywell thermostat, first, try to increase the brightness. Then change the batteries to perform a reset and make sure that the circuit breaker switch is flipped ON.

If however, the problem is still there and you don’t think that you’ll need repair service, you can contact Honeywell customer service for another round of troubleshooting.

Your thermostat is the control center for your HVAC system. Programmable thermostats feature easy-to-read screens that allow you to program your heating and cooling settings and view the current temperature in your home. However, if that screen goes blank, you can’t do any of this. Honeywell and other brands of programmable thermostats typically show a blank screen when there is no power going to the wall unit.

A Honeywell thermostat will flash a low battery signal for about one to two months before the batteries in the wall unit run out completely. If you’ve been away or haven’t noticed this warning and the batteries can no longer provide power to the screen, it will go blank. This is easily fixed by removing the cover on the wall unit and replacing the batteries. You may have to reset the unit and reprogram your settings once the display returns.

If your thermostat is wired directly into your home’s electrical system, a blank screen indicates there is no power going to the unit, which means there may be a tripped breaker or a problem with the wiring. If the breaker controlling the unit hasn’t tripped, contact an HVAC technician or an electrician to inspect the wires. Sometimes a loose connection is enough to stop power from running to the unit. If this doesn’t resolve the issue, have the thermostat replaced.

Like with other programmable thermostats, Honeywell thermostat’s easy-to-read screen allows you to easily program your cooling and heating settings and enjoy blissful comfort at home.

You see, programmable thermostats such as the ones made by Honeywell are pretty much like your PC (they have software controlling them) so resetting it (rebooting it) can be helpful.

Go ahead and re-insert the batteries but not in the normal way- you insert them backward, so the –ve (negative) pole will line up with the +ve (positive) terminal.

Of course, the final way to reset the thermostat- If all else won’t work- is by switching OFF power (turn the circuit breaker off) for a few minutes then turning it back ON.

You cannot rule out this happening to your unit (it all boils down to the model) so it’s worth inspecting the wiring and repairing all the loose connections you might find.

Next, proceed to remove your thermostat’s cover. It is not really difficult – all you have to do to have the cover easily pop off is grasp the sides then pulling it off without too much force or strength.

Locate the screws that fasten the base of your thermostat to the wall (for the most part, you will notice anything between two to four screws depending on your model).

Check all around and see if there might be any wires hanging loosely (or not attached) and if you find any, connect them back the correct way (use fastening screws where necessary). You also want to check that there are not damaged or frayed wires as these could also be causing the malfunction (damaged wires may need to be replaced).

The next step is removing the batteries from the battery compartment at the back of your thermostat. Use the same old trick to open the door (insert a coin or something similar).

You want to access the inside so now you should pry the cover (off the front) of the thermostat, again without using excessive force- The last thing you want is to cause more damage by pulling it out forcefully.

Your last step is reconnecting the pair of ribbons to the board. You should finally put the thermostat back together starting with the circuit board and screen.

If the above troubleshooting ideas do not fix your defective thermostat and the screen still won’t respond to touch, perhaps it’s time you seek professional help.

Your Honeywell thermostat has a critical job. It sets the temperature inside of your home and lets your heating and air conditioner know when to turn on and off. When it’s not functioning properly, you could be faced with severe heating and cooling issues that not only affect the comfort of your home but your wallet as well. If your Honeywell thermostat isn’t working, here are a few tips to troubleshoot the issue.

If you have an analog Honeywell thermostat and it isn’t functioning correctly, test the settings. Most analog thermostats have one switch for indicating heat, cool, and off and a second switch for turning the fan on auto or off. Turn the thermostat to heat and turn the temperature up to see if it turns on. If it does, your heater is working. Next, switch the thermostat to cool and turn the fan on auto. Turn the temperature down and wait. If your air conditioner turns on, it’s working correctly.

If your heat and air conditioning don’t turn on, there may be an issue on the inside of the thermostat. The next step you will want to turn the electrical breaker off that controls the unit first. Then carefully remove the cover, after turning the thermostat off, and check the wiring inside. It would help if you also looked everything over to make sure that it’s clean. If everything looks good, there could be an issue with your HVAC system, or it may simply be time to replace your thermostat.

One of the most common issues with digital thermostats is that there is no display. This means you have a blank screen. There are a few different issues that can cause this to happen. One reason is that the batteries are dead. Replacing them can often solve the problem.

There may be no display because an access door on your HVAC system isn’t completely closed. Some types of units have a switch that activates the system when the door is closed all the way. If you don’t close the door all the way, the system won’t activate, which cuts the power to your thermostat. Check to make sure all access doors are closed.

Another common issue for not having a display on your Honeywell thermostat is because the circuit breaker may have been tripped. HVAC systems typically have their own circuit breaker, so check the box to make sure the switch is on.

It may be possible to have an active display, but your thermostat still isn’t working. If your home feels too hot or too cold for the temperature displayed on the screen, there could be a broken or malfunctioning temperature sensor. Use a thermometer to measure the temperature where the thermostat is located. If they don’t match up, there’s a good chance that it’s that sensor. The sensor can be replaced, or you may need to replace the whole thermostat.

Other issues that can occur, even with an active display, include incorrect day and time settings, loose wires, and incorrect jumper settings. Power outages can throw off the clock and day of the week settings, which can then result in improper operation. Check these settings. You should also make sure that your jumpers are set to the correct settings for your HVAC system.

Both analog and digital Honeywell thermostats are very dependable, but issues can still arise. In many cases, you can troubleshoot the problem and fix it. If nothing seems to be doing the trick, though, it is best to consult with an expert.

Picture this: You walk up to your thermostat to adjust the temperature in your home, only to be greeted by a blank screen. You tap on it and press the buttons — still, nothing. Since your thermostat is the control center for your HVAC system, you can’t afford to go too long without it working properly.

Remove and replace the batteries from your Honeywell system as directed in the instructions for your specific model. The batteries may be within your battery compartment or control panel. Be careful to make sure they are correctly oriented within the thermostat. Once replaced, test the system for operation and responsiveness.

Is your Honeywell Thermostat screen not responding? You are not alone! That seems to be one of the common problems with Honeywell thermostats and other brands.

However, it doesn’t mean your thermostat is faulty whenever this happens. Sometimes, the screen may stop responding when the batteries are low or bad, or when the circuit breaker trips off.

So if your Honeywell thermostat screen is not responding, you want to keep reading as this post contains valuable information for you. Let’s head right into it!

When your thermostat screen goes blank and is not responding, it becomes near impossible to program your heating and cooling settings and also view the current temperature in your home. Sometimes, this issue doesn’t require an HVAC expert, so you can attempt to fix it yourself. And here are some troubleshooting steps to try if your Honeywell thermostat screen is not responding.

When your Honeywell thermostat screen stops responding or creating fading digits, the first place to look is the batteries. The batteries may be drained out or bad, causing the screen not to respond as well as it should. This is especially true if your thermostat is running completely on batteries.

This is another common reason the screen of many Honeywell thermostat users stops responding. There may be a loose wire on the back of your thermostat, and your thermostat needs all wires properly connected before it can communicate well with the screen. However, you can fix this on your own too—no special skill or technical know-how is required!

To check for any loose wire at the back of your thermostat, remove its cover. Next unscrew the system from the wall, and you will see a bundle of thin wires located just at the back of it. Check to see if any of these wires are loose, so you can put them back in place. You should get your screen working properly again after fixing the loose wire.

Most HVAC systems come with their own circuit breaker, and during a power outage or power surge, the circuit breaker can trip off. When this happens, it can cause your Honeywell screen to refuse to respond. So, check the circuit breaker to be sure it is not tripped. If it’s tripped, manually flip it off and then on again.

One of the cables is marked for the touch screen while the other for LCD. There are two small tabs on either side of the cable. Slightly pull it up and back to ensure it is fully seated. This should bring back the display screen but don’t forget you need to be extra careful with the cables because they are fragile.

This may not be the solution you expect to see, but that is likely going to be your only option when you have tried everything mentioned above, and nothing seems to work. It shows that your Honeywell thermostat may be faulty and so you will need to replace it with a new one.

And on the one hand, you may want to have an HVAC technician examine the faulty thermostat to see if it can still be fixed. If not, you should get a new thermostat.

There are several reasons for this. If your thermostat runs on batteries, maybe your batteries are dead. But if it is wired into the house’s electrical system, it might be some wiring issues causing your thermostat screen to go blank. Check the steps highlighted above to fix it.

As mentioned, one major reason the Honeywell Thermostat screen goes blank is when the batteries are drained out and can no longer supply power to the screen. Your batteries may drain out without notice—especially if you have been away for too long.

To reset the thermostat even when the screen is blank, you will have to replace the batteries. Remove the cover on the wall unit and replace the batteries. The display should come back on immediately after you replaced the batteries.

Though some cases of a ‘thermostat screen not responding’ may require a replacement, it doesn’t happen all the time. You could easily fix the bug yourself sometimes.

A thermostat is a vital piece of HVAC equipment. These machines allow us to easily change the temperature in our home or business, leading to sustained comfort. While there are many different types of thermostats out there, a Honeywell thermostat is among the most popular.

As these devices do an exceptional job at keeping us comfortable, problems do happen from time to time. In this post, we’ll talk about some of the most common Honeywellthermostat problems, including some troubleshooting tips.

Is your Honeywell thermostat not working at all? This can be a frustrating problem to deal with. Luckily, you can take some easy steps to try to fix the issue.

First, if you have an analog Honeywell thermostat, you can test the settings to ensure it’s set up correctly. When looking at your thermostat, you’ll notice there is one switch for heat, cool, and off; and there is a second switch for powering the fan. To try and solve the problem, turn on the heat setting and crank the temperature up to see if the system does anything. If it does power on, you’re in luck.

Now it’s time to test your air conditioning. Change your thermostat to the cool setting and turn the fan to auto. Then, turn the temperature down and wait a few seconds. If you hear the system working, you’re good to go! If not, there could be another issue going on.

If your thermostat isn’t working at all, there could be a problem internally. You could examine the inside of the thermostat to see if there is an issue. First, head over to your electrical breaker box and turn off the power source to your thermostat. Next, turn the thermostat off and carefully remove the top cover of the unit. Look at the wiring and check if anything is loose, broken, or disconnected. Also, check to see if everything is clean.

If the inside of your thermostat is filthy or there is loose wiring, that could be your problem. If you don’t find any issues under the cover, there could be something going on with your HVAC system, or you could be due for a thermostat replacement.

Another common problem is a display screen that appears blank when everything is powered on. Luckily, there are a fewHoneywell thermostat troubleshootingtips that can help.

If your digital thermostat doesn’t display anything at all, leaving you with a blank screen, you could have dead batteries. Replace your batteries to see if that helps.

It"s also possible that you have a tripped circuit breaker. This can also cause your thermostat to display a blank screen. As HVAC units tend to have their own circuit breaker, be sure to examine this to make sure the switch is set to the right position.

Is your thermostat not maintaining heat in the home? Or does your thermostat not turn on heat at all? In this case, check your batteries if your display screen is blank. If your display screen is working, examine your wiring to see if there are any issues.

Another tip is to make sure your thermostat is completely level. If it isn’t, the mercury switch in your thermostat could lead to an incorrect temperature reading. This can cause your system to continually power on and off. To try and fix the issue, make sure your thermostat is 100% level.

Is your Honeywell thermostat not cooling? Or does it seem like the temperature reading doesn’t match the actual indoor temperature? In this instance, there could be an issue with the temperature sensor. To troubleshoot the problem, grab a thermometer and measure the actual temp near your thermostat.

With how advanced Honeywell thermostats have become, trying to troubleshoot these problems can be confusing and frustrating. No matter what issue you"re having with your HVAC system or any of its equipment, calling an HVAC professional can be a very smart decision.

While it’s not dangerous to change batteries or make a small adjustment to your thermostat, working within your HVAC system and its electrical components can pose many risks. If you ever don"t feel comfortable troubleshooting your thermostat or HVAC system problems, we highly advise calling an HVAC professional. They know exactly what they’re doing and can diagnose the problem quickly.

To try and avoid thermostat problems in the future, pay attention when your thermostat is first installed. Learn how to set Honeywell thermostat, and you can maybe even ask how to solve some common thermostat problems. Additionally, there should be a manual that comes with your Honeywell thermostat, and that booklet should have a section regarding Honeywell thermostat troubleshooting. This can be a great resource when trying to solve these problems.

If you"re constantly dealing withthermostat issues, it may make sense to buy a replacement. This equipment wears down over time, and a new model may bring many advantages. In fact, as your ineffective thermostat was possibly causing poor energy efficiency, a new thermostat could bring tons of savings on your energy bills.

Your thermostat is important. It is the one device that can control the temperature in your home. That being said, it can be more than a little concerning when you go to turn on your AC and find a blank thermostat.

However, most of the time, a thermostat blank screen can be easily fixed if you can find out what caused it. Here are some possible causes of a blank thermostat and how to fix it.

Before you jump to conclusions, make sure the thermostat isn’t just turned off. If you don’t live alone, there is always the chance that someone else turned it off by accident and there is nothing to worry about.

Some thermostats automatically adjust their screen’s brightness level when there is too much light in the room to save battery power. Be sure to check and see if your thermostat is at a lower brightness before you move on to other potential causes.

Another common cause of a thermostat blank screen is dead batteries. If your blank thermostat runs on batteries, try replacing them – and see if that turns the thermostat back on.

If you own a Honeywell thermostat, the blank screen could be an indication of a furnace door that wasn’t completely closed. These thermostats are programmed to shut off entirely if a furnace door is open. To rule this out, double-check to make sure your furnace door is fully closed.

Most thermostats are connected to a home’s main electrical system. If this is the case, it’s possible that the thermostat or some other electrical device caused the breaker to trip. Go to the breaker, and flip the switch to reset the circuit. If the screen turns back on, you found the cause.

Sometimes, the issue is with your AC itself. Every AC has a safety switch installed in the drain pan that turns the system, thermostat included, completely off if it detects a hazardous problem. If the safety switch indicates a problem, contact an HVAC professional to inspect your AC.

It is always a possibility that your thermostat has reached the end of the road and needs to be replaced. Most thermostats last around 10 years. Therefore, if your thermostat has been around a while, has a blank screen and isn’t working, it may be time for a new one.

There are three kinds of thermostats: Manual—This is the typical dial-shaped thermostat. You won’t have error codes with this type, but it’s also the least efficient for saving on utility bills.

Programmable—This thermostat includes a digital screen and arrows you touch to choose your desired temperature. You can also set daily programs to decrease the temperature when you’re gone and increase it when you return.

Smart—You won’t have to schedule any programs on this thermostat, as it learns your routine. It intuitively raises and lowers the temperature when you or other household members are away to help you save on utility costs. You can also adjust the temperature anywhere via your phone or other Wi-Fi-enabled device.

If the screen is blank on your programmable thermostat, you may need to put in new batteries. If that doesn’t take care of the trouble or you have a smart thermostat, there could be a wiring issue.

In the summer, confirm you schedule the thermostat beneath the ambient temperature. When it’s cold, confirm it’s higher. This sounds silly, but we’ve seen it take place a lot of times.

A blank thermostat screen is scary for any homeowner, especially in the middle of winter or the heat of summer. Is it simply a matter of replacing the batteries? Is there faulty wiring somewhere? Or is it something that’s going to cost you major bucks? Maybe your whole HVAC system is broken, and you’re going to need to replace it all!

Don’t panic. If you have a blank thermostat screen, there may be a simple solution to your problem. Here are some of the most common reasons why your thermostat screen might be blank – as well as ways to fix it.

Does your HVAC system have a power switch that can be turned on and off? If so, the switch should be turned to the “on” position. Some thermostats will turn off when your air conditioner is off.

Honeywell thermostats are particularly sensitive to this issue. If your furnace door isn’t fully and securely closed, the screen on your thermostat might appear blank.

Many programmable thermostats allow you to change the brightness setting. If your settings are too low, it might seem like you have a blank thermostat screen. Some thermostats, including the most popular Honeywell thermostats, will dim the screen at a certain time (typically very early morning) to avoid burn-in. Wait and see if the screen brightens again.

Some thermostats require battery power, and if the battery dies, your screen will go blank. Try changing the batteries. Clean the battery contacts with a pencil eraser and gently pry out the spring contact so you get the best connection.

Smart thermostats like the Nest use the wires connecting the heating and cooling system to recharge. But if the battery drains down, you’ll see a blank thermostat screen (or possibly a blinking light) as it recharges. Once it’s recharged itself, you’ll be good to go. If this happens on several occasions, some component of your HVAC system may be broken. The thermostat would need to use more power than usual. In this instance, have your HVAC system checked by a technician.

Faulty wiring could be the problem, especially if you’re having trouble right after installation. Thermostats from Wiser Air, for example, require a C terminal, so you might need a special wire extender. Most thermostats need a 24 VAC power supply. If the thermostat was hooked up to 120V or 240V power for any length of time, it could be damaged.

If you blow a fuse on the furnace control board, your thermostat won’t work properly. Open your furnace control panel and check the connection between your thermostat wires. Look for a purple 3-amp or an orange 5-amp fuse on the board, and check that it’s intact. If it’s blown, you have to replace it. You can read more here about why your air conditioner might be causing your fuse to blow.

Furnaces have high-limit switches to keep them from overheating. If your screen goes blank after several minutes of heating, it could be because the high-limit switch is tripping. This is commonly due to restricted airflow because of broken or dirty parts in the HVAC system. A failing fan motor can cause your electrical components to pull in more amperage than usual, tripping the high-limit switch. Any of these could cause a blank thermostat screen.

If your drip pan fills up, it can activate a float switch which will cut power to your HVAC system. When your drain line does not empty outdoors, it could cause a blank thermostat screen. If you’ve tried rebooting the thermostat and changing the batteries, don’t forget to check the drain pan. Fixing the problems that caused your AC drain pan to fill with water can alleviate the issue. Refer to your manual to see if you need to reset the float switch.
