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.

Ecobee’s top-tier model outperformed all other thermostats, and it comes with the best remote sensor we’ve tested. It has an air-quality monitor, as well as a built-in microphone, speaker, and Alexa for voice control, but it also works with most smart-home platforms.

The Ecobee Smart Thermostat Premium consistently kept my home more comfortable than any of the other thermostats I tested, and it even saved more energy in the process (on average, bills were at least 7% lower than in the same period the prior year). This device can be controlled directly from its touchscreen, remotely using a smartphone or tablet, or by voice command via a built-in Alexa speaker (or with an external Google or Apple smart speaker). An included remote SmartSensor detects your presence and your temperature, and it can be placed in an area that’s too cold or warm so the Ecobee can better balance temps around your home. (The unit comes with one sensor, and you can add up to 32.) There’s a bit of a learning curve involved in getting the most out of all the Ecobee thermostat’s settings, but this pays off in the end.

We also recommend the Ecobee Smart Thermostat Enhanced, a slightly stripped-down model that functions identically but doesn’t have a built-in Alexa smart speaker, air-quality monitor, or remote sensors (they are compatible, but you have to buy them separately). If you have a smaller home or don’t need a remote sensor or voice controls, this is a great, less expensive option.

Nest’s most-advanced smart thermostat features a larger, crisper, and more useful display than its predecessors, as well as wide compatibility with HVAC systems.

The Google Nest Learning Thermostat (3rd generation) learns your preferred heating and cooling settings. Then it automatically creates a schedule that should maximize efficiency, so you don’t have to program the device yourself. It installs easily and supports geofencing, and it’s compatible with most home climate-control systems. You can also add optional Nest Temperature Sensors, little wireless pucks that measure the temperature in rooms without a thermostat. If you have trouble spots that are often too cold or hot, you can place one of Nest’s sensors there and expect your room to be more comfortable. Unlike the Ecobee’s SmartSensors, however, Nest’s Temperature Sensors don’t detect presence or movement (the thermostat itself does, though), so they can’t be used to trigger heating or cooling based on someone being in a specific room.

Though Amazon’s Smart Thermostat isn’t as sophisticated as other picks, it works well, is widely compatible with HVAC systems, and is simply inexpensive.

The Amazon Smart Thermostat may be basic, with simple controls and rudimentary AI, but it does what it does well, and for some people that makes it ideal. This model can be configured to run on a timed schedule, or, using Alexa Hunches (Amazon’s term for Alexa’s AI-based learning feature), it can eventually learn your patterns and suggest customized settings. Unlike Nest’s hallmark mechanical control dial or Ecobee’s smartphone-like touchscreen, to adjust the Amazon Smart Thermostat, you first tap the white touch-surface face to wake it up and make controls visible. You can also adjust the temperature setting using voice commands to an Alexa device or with the Alexa app in your smartphone. The one conspicuous missing feature we’d like to see is compatibility with remote sensors, which our top picks have.

A pricey but practically perfect option for adding smart controls to electric baseboard heaters, the Mysa Smart Thermostat uses scheduling, geofencing, and a smart eco mode to save you money while imperceptibly using less energy.

The Mysa Smart Thermostat will make your “dumb” and inefficient electric baseboard heating far more cost-effective. It’s our only pick in what is an admittedly limited field—it works with 110-volt (up to 240-volt) electrical heating sources. We like its clean, modern design, the fact that it doesn’t require a separate hub, and that it works with all the major smart-home systems. The Mysa uses geolocation and artificial intelligence alongside scheduling and zoning to heat your home efficiently and save energy while keeping you comfortable.

If the thermostat’s display is dark, a lack of power may be the issue. Try replacing the batteries, then check for a blown fuse or tripped breaker in the electrical panel. If the thermostat is still unresponsive, make sure the breaker is shut off and remove the cover. If it looks dirty inside, use canned air or a soft artist brush to clean away accumulated grime that may be affecting its functionality. Then look for issues like loose wiring or terminal screws and tighten them up. If the wiring looks corroded, consider replacing the thermostat.

Dirty thermostat components can cause this issue, so clean the inside as per the above instructions first. A jarring bump can throw a non-digital thermostat off level and cause setting and temperature discrepancies too. To fix it, place a carpenter’s level just above the device and make adjustments until it’s level again.

If you have a mechanical thermostat, a frozen anticipator is another potential culprit. Locate the arm that’s attached to a round dial and try gently pushing it either direction to get it unstuck. If these fixes don’t work, consider the thermostat’s location. It may need to be moved if it’s exposed to heat sources, direct sunlight or drafts or installed far from the main living areas.

An off-kilter or dirty thermostat can cause this, so troubleshoot those issues first. Another possibility is an improperly calibrated anticipator. You may be able to lengthen the cycle by adjusting the anticipator lever one notch at a time toward the word “longer” on the dial. If this doesn’t work, it may be time to upgrade to a programmable thermostat.

Since the Nest Learning Thermostat launched in 2011, no other smart thermostat has emulated its core function — learning your schedule and adapting to it automatically, so you don’t have to lift a finger. This feature has made the Nest one of the best smart thermostats (lots of) money can buy for years. But just a decade on, Amazon has finally done it. The online shopping giant’s $60 Amazon Smart Thermostat can intelligently determine if you’re home, away, or sleeping and automatically adjust your climate to keep you comfortable and potentially save you money. And you don’t have to program anything.

Amazon worked with Resideo (owner of the historic thermostat brand Honeywell Home) to develop the thermostat, and its internals are very similar to the Honeywell Home T9 and T5 smart thermostats. It’s compatible with most 24 volt HVAC systems (you can check compatibility here), but doesn’t support systems with more than three stages or multi-speed fans. Together, Amazon and Resideo seem to have finally cracked the smart thermostat conundrum, and the Amazon Smart Thermostat’s learning feature — called Hunches — is very good. No, it isn’t quite as good as Nest’s, but it also doesn’t cost $250. So, tradeoffs.

Hunches — which are part of Amazon’s broader Alexa smart home platform — are AI-driven decisions that use data from your Alexa smart home to decide what to do with your temperature. It follows, unsurprisingly, that the more Echo smart speakers and displays you have in your home, the better it will be. According to Amazon, Hunches also uses “select other smart home devices like lights, locks, and sensors” to determine if you are home or away, as well as geolocation of yours and your household members’ smartphones (everyone has to have the Alexa app installed and location settings turned on for the thermostat).

For the next three days, it turned on the heat a little too early, and I had to go into the thermostat settings in the app to tell Alexa its Hunch was wrong. After three times telling it that, no, we do not wake up at 4:31AM, it reverted to our regular wake-up time.

The controls on the Smart Thermostat are three touch points on the bottom. LED icons show you the ambient temperature by default, then the current set point when you tap on one of the arrows.

It’s hard to quibble much at this price, however, because at least it’s trying to be smart. Outside of Nest and Ecobee, few thermostats are actually smart. Most are just controlled remotely — either by an app, voice, or geolocation (where it adjusts based on whether your smartphone is at home). This is all very handy, but it’s not intelligent.

Case in point, the new Nest Thermostat has no advanced AI features of which to speak. While it can do useful energy-saving or comfort-increasing tasks such as preheat or cool the home or use the fan to circulate air to more efficiently use air conditioning, it doesn’t have the same learning features as the Nest Learning Thermostat and its smarts are largely reliant on Google’s home / away modes, which can use geofencing, on-board motion sensing, and other Nest smart home products to determine if someone is home. As with the Learning version, you can choose which devices feed into the home / away modes, which you can’t do with the Amazon Smart Thermostat.

If you don’t like the idea of Amazon controlling your climate willy-nilly, the Smart Thermostat has a standard scheduling option. With either set up, you can also use Alexa’s Routines to have your thermostat do specific things based on time of day, when a smart home device tells it to (such as a compatible temperature or motion sensor), or with your voice. These functions are available to any smart thermostat that works with Alexa, but you will not find one as inexpensive as this one.

The closest competitor price-wise — the Wyze Smart Thermostat — is $80, and the Honeywell Home T5 and T9, whose hardware the Amazon thermostat shares, start at $120. Most other smart thermostats are over $100, including the Emerson Sensi, the Lux Kono, and then Ecobee’s and Nest’s start at $180 and $130, respectively.

Of course, almost all those thermostats work with multiple platforms. The Amazon thermostat only works with Alexa. And while the coming smart home standard Matter — which promises interoperability between ecosystems — may change that, Amazon has not confirmed that this device will be upgraded to support Matter.

While this thermostat is inexpensive, it doesn’t look cheap, unlike the Wyze Smart Thermostat, which has a plasticky feel and an odd, oblong design. The simple, clean design of the Amazon Smart Thermostat will fit in with most homes, and because it doesn’t have an LCD screen, it doesn’t scream “high tech” like others in this space.

Most of the setup and programming of the thermostat requires the Alexa app. And, as you’d expect from an Amazon device, it’s designed to be controlled with your voice. This makes it surprising that the Alexa voice assistant isn’t built in as it is in some of Ecobee’s models. Instead, you need to have a compatible Alexa device for voice control.

Physical installation of the Smart Thermostat is identical to that of Honeywell Home’s T9 or T5 and requires shutting off the power and wiring the base.

Integration with Alexa is straightforward and doesn"t require a skill or account linking. Setup and installation of the thermostat is similarly simple. You will want to check if your heating and / or cooling system is compatible first, however. And if you don’t have a C-wire, you will need to opt for the $75 version that comes with a C-wire adapter and plan for a much more involved installation. (C-wire is short for common wire and supplies power to your thermostat. Most connected thermostats need a C-wire to connect to Wi-Fi, which is a big power drain.)

Everything you need to install the thermostat comes in the box, including a screwdriver and handy labels for identifying the thermostat wires. The Alexa app guided me through installation very well, making it clear which wires should go where, connecting the thermostat to my Wi-Fi, and testing that everything was working correctly. If you are uncomfortable with wiring or aren’t familiar with how your heating and cooling system works, you should get professional help. Messing up your HVAC system will be a costly mistake.

Using the Alexa Smart Thermostat was a smooth experience. The Hunches worked well (other than my 4:30AM blip), turning my heating down between 11PM and 11:30PM every night and back on at 6AM in the morning. Switching to away when the house was empty during the day was less reliable, and in my week of testing, I wasn’t able to get a firm read on how long it takes to adjust to an empty home — this is a key component of any energy savings this device will get you, so I’ll update this review once I’ve had more time to evaluate the feature. However, you do have the option of telling Alexa, by saying “Alexa, I’m leaving” as you walk out the door.

Controlling the thermostat with voice using an Echo speaker or display was smooth — and with the latter, an interactive screen pops up for further control if needed. You can control the mode with voice, too, switching to heating or cooling, and even ask Alexa to change the temperature when no one is home.

In order to use the Amazon Smart Thermostat, you’ll need to download the Alexa app for iOS and Android. An Amazon account is required to sign in. By signing up for one of those, you must agree to its conditions of use.

Once you connect the thermostat to Alexa, you need to agree to Amazon’s conditions of use and all of the terms found here. You can explore the documentation at that link, but below, we’ve listed the 12 terms that you must agree to:

But the app was a more frustrating experience. It takes four or five taps to get into the thermostat screen, although eventually I was able to add the thermostat to the new Favorites section in Alexa’s devices page, which speeds things up a tad. Once on the correct screen, the controls mimic those of the physical device, plus there’s a humidity reading (the thermostat has a humidity sensor in it, a temperature sensor, and an ambient light sensor for adjusting the brightness of the LEDs).

The one other area I ran into issues with was using the thermostat in a two-zoned home. As with all thermostats, you need one for each zone in a multi-zoned systemand they control the climate independently.Butthe Alexa app wouldn’t let me set the home, away, and sleep temperatures separately; whatever I set for my upstairs zone also applied to my downstairs zone. That’s not ideal if you like to sleep at 66 degrees but want your living room and kitchen to drop to 62 at night to save energy.

Switching the upstairs thermostat to a schedule and keeping the downstairs on Hunches did allow me to have different set points, but that’s not an ideal solution. This is a problem in the Alexa software, as with every other thermostat I have tested in this two-zone system, each thermostat controls each zone entirely independently.

The other drawback is that there are no temperature sensors designed specifically for the Alexa Smart Thermostat. It’s possible to set Alexa Routines to use with the temperature sensors built into some Echo speakers or with compatible third-party motion or temperature sensors like those from Centralite and Aqara, plus Amazon’s new Smart Air Quality Monitor will work with Routines. But that integration isn’t as seamless or as easy to use as thermostats with native temperature sensors.

The Nest Learning Thermostat, the Ecobee thermostats, and the Honeywell Home T9 Thermostat all work very well with their own external sensors, but these thermostats cost $100 to $150 more than Amazon’s. You also don’t get useful extra features such as the time and weather displayed on this cheaper thermostat or integration with platforms or voice assistants other than Alexa. Still, if those features aren’t important to you, then you really can’t go wrong with this device.

Based on my testing, it’s hard not to be impressed with the Amazon Smart Thermostat, and not just because it’s cheap. I have tested almost every smart thermostat released since the Nest Learning Thermostat launched a decade ago, and this is easily one of the best.

I would still choose a Nest Learning Thermostat for my home because I love the look and feel of it, and I have more control over how it manages my home’s climate (plus it works with both Google and Alexa). However, I thoroughly recommend the Amazon Smart Thermostat over the new Google Nest Thermostat, which is a dumbed-down version of the original (something of a theme with Nest devices these days). Honestly, the Amazon Smart Thermostat is the budget thermostat Google Nest should have made.
