There is no doubt that thermostats are one of the most comforting aspects of a smart home. They help you truly relax and cope with unbearable temperatures.
Whenever you get back from work and are chilled to the bones, you can easily instruct your thermostat to warm down the house before you reach your house.
This is possible only thanks to the advancements that smart technology has brought to thermostats. Many companies like Honeywell offer these smart thermostats. With only a tap, you can easily change the temperature of your house at any time.
How To Fix Honeywell Thermostat Not Reading Correct Temperature?
Quite a few users have noticed their Honeywell thermostat not reading the correct temperature. They compared the readings with other devices to find out that the results were far from accurate.
Thermostats, especially from Honeywell, are known to read incorrect readings every now and then.
As frustrating as it sounds, you can easily fix this by applying a few troubleshooting steps. This is exactly what we will be doing through this article. We will be listing a few different ways how you can fix this issue. So, let’s get started!
1. Clean Your Thermostat
An unclean device is something nobody wants to use, and that’s not just because it looks bad. One of the many things that may cause your thermostat to read incorrect temperature is dirt and debris. This is why we recommend always cleaning your thermostat as much as you can.
Technology is highly sensitive, and as a result, it’s very susceptible to damage. This includes damage from the smallest of sources. For example, a little bit of dirt going slipping inside from a crack and getting over the wires, or any other similar thing that comes to mind.
So, it’s up to you to make sure that your Honeywell Thermostat is in the cleanest and best condition it can be. Regularly wipe it with a cloth to make sure dust doesn’t collect on the surface.
Other than that, don’t be afraid to open it up with some tools to inspect the inside if you think some dirt or debris seeped through.
Doing all of this helps you maintain both the integrity of the thermostat and avoid unnecessary problems. Just open the cover of the thermostat and give it a good clean. Once you start doing this regularly, problems like these will be a thing of the past.
2. Change Air Filters
Absolutely no one wants to breathe bad air. Well, a big problem with thermostats and other similar devices is that they can negatively impact the quality of air in your home.
But, they’re also equipped with air filters that prevent this. But, what happens when you don’t take good care of these filters?
Old or poor air filters can also cause your thermostat to cause all kinds of issues which also include the one that you are facing. They negatively impact the quality of air, and the functionality of the thermostat is very limited if they aren’t in good condition.
Due to the nature of their functioning, these collect lots of dirt over time. Because of that, they inevitably go bad even if you take good care of them. As a result, you should check your thermostat and see if they are due for a replacement.
3. Change Your Thermostat’s Position
You have to be smart when it comes to installing a thermostat in your home. Just think a little; if the device isn’t installed somewhere it can easily cool or warm the house, but it won’t do any good to you.
That’s why it’s very important to set it in the right position, which brings us to this next solution.
Your thermostat could be installed in a very awkward position. If that is so, then this is what may be causing your thermostat to give slightly wrong readings. In order to fix this, you will simply have to move your thermostat to a better position.
If you don’t know what the best position for the position for it is, we would recommend asking the person installing the device for some advice. They will be able to carefully map out the house and provide insights on where you should position it for the best results.
4. Faulty Sensor
If you aren’t familiar with what the sensor is on a thermostat, it’s the component responsible for keeping track of the temperature in the first place. Without it, the device can’t accurately read what the conditions in its surroundings are.
What we’re trying to say with this is that another thing which could cause your thermostat to read the wrong temperatures is the sensor itself.
Since it’s responsible for checking the surroundings and providing feedback to the device, the reason why a faulty sensor could cause this is obvious.
Unfortunately, there really isn’t a way of fixing a sensor. This is why in case you have a faulty sensor in your thermostat, one of the only things that you can do is to get it replaced.
You’ll have to contact a repairperson for this or get a new thermostat entirely from Honeywell if your warranty is still active.
5. Your Thermostat May Be in Need of Levelling or Calibration
One of the last things that you will need to check is whether your thermostat is completely levelled or not. Although not as important as the newer digital thermostats, having an older thermostat requires you to level it correctly.
Also, check whether your thermostat needs to be calibrated or not. You will have to read your thermostat’s manual on how you can calibrate the thermostat properly.
The Bottom Line
In this article, we have successfully managed to explain how you can resolve the Honeywell thermostat not reading the correct temperature. Following the 5 steps mentioned above will help you in doing so.

Same thing, temp off by 4 – 5 degrees on HONEYWELL model TH3210D1004. Sensor issue ?
I have the statndard round non programable thermostat. The temperature sensor does not corespond with the temperature set. I have set up other devices for temp readout and the temp set always corespond with the other but not the one on the thermostat. My question Why? I had another one it also did the same thing.
