Besides this, installing a Honeywell thermostat can help maintain a consistent temperature in your home for a longer period. Whether you want to make your home cool or warm, you will be able to do so through a voice command or a touch of a button. Typically, the Honeywell thermostat will follow the commands given and thus prompt the AC in your home to either cool or warm your house at a given time period.
Although the Honeywell might be turning on the AC as desired, there are some instances when it may fail to do so. If you are a first-timer, you can freak out. The good news is that we shall take a closer look at why the Honeywell thermostat won’t turn on and how to troubleshoot such issues on the go.
Reasons Why Your Honeywell Thermostat Won’t Turn On AC And How To Troubleshoot
Ideally, your Honeywell thermostat should turn on the AC at the right time so that you can either warm or cool your home promptly. If you had gone to work, you can program the Honeywell thermostat and command it to either raise the temperatures or lower them to a certain degree.
By the time you get home, you will find your home at the right temperature and thus enjoy the much-needed comfort. However, if the Honeywell thermostat cannot do this with utmost precision, chances are that the following reasons are responsible for that problem and their respective troubleshooting methods.
1) Dead batteries
Some thermostats usually rely on the main power supply while others rely on batteries for them to function. If your model belongs to the latter category, chances are that the batteries have died and need to be replaced promptly. Once the batteries have died, the thermostat will no longer show anything on the screen. In addition, the screen will be unresponsive and can even start flashing. All these are a clear indications that your batteries are dead and you need to purchase new ones. Once you purchase new models, you can now command the Honeywell thermostat and see if it will turn the AC on or not.
2) Dirty thermostat
Besides having dead batteries, your thermostat may fail to turn on the AC as desired due to dirt and dust. Just like other appliances, the thermostat can start collecting dust and dirt during the summer months. In most cases, these elements are normally trapped behind the cover of the thermostat.
If these elements are not removed in good time, they might lead to various problems. One of them is the unresponsiveness of the AC whenever you command the thermostat to either raise or lower the room’s temperature. To be on the safe side, you should remove the cover and then use a spray can in order to eliminate these elements on the go.
3) Loose wires
Whether you have an old model or a new model, the problem of loose wires can be imminent in both models. The good news is that you can now check this problem on your own, without essentially having to engage a professional.
All you need to do is to turn off the power and then remove the thermostat from the wall. Thereafter, you can check the terminals of the device and see if there are any loose wires. If there are some loose wires, you can fix them back as stipulated in the device’s manual. In case you cannot do this on your own, seek the services of a professional technician near you.
4) Unleveled thermostat
For your thermostat to read the temperature more accurately, the mercury switch inside it has to be positioned well. Here, it should be in a level position. In case someone mounted the device wrongly, the level may tilt and thus make it difficult to take the readings of your house’s temperature.
In fact, this can make the unit turn on and off every now and then, throughout the day. Consequently, the AC will not be turned on as expected. If you discover that the thermostat is not positioned well, you can remove it and reinstall it. For optimal results, ensure that you use a level in order to mount the device perfectly on a level position.

Just like other components, the sensor in your unit might have outlived its usefulness. As a result, you may be required to either replace it or just upgrade your current model. Unlike other problems, this one is common among those models that have been in use for ages.
Instead of replacing the sensor in that particular unit, you can choose to purchase a better model with better features. The good news is that you will not miss a model that suits your needs at your brick-and-mortar home improvement store or online. More importantly, talk to an experienced HVAC technician so that you can purchase the right model for your home.

To solve this problem, you should try to flip the circuit breaker and determine if your model is able to get power afresh or not. Once you do so, try to listen for a ‘Click’ sound. If you do not hear that sound, the Honeywell thermostat is not yet powered on.
In this case, take a closer look at the circuit breaker and determine if it is overloaded or not. If this is the case, you may have to alter the manner in which you have connected the devices in your home. Ideally, it should not keep on tripping.
