There is no doubt that the thermostat is an important piece of equipment in your home. As the director of your HVAC operations, the thermostat helps to control the temperature in your home. Based on the internal thermometer, your device will call for heating or cooling based on the settings and your desired temperature. Aside from helping to keep you comfortable, a properly functioning thermostat can also help save you money on your energy bills by regulating your system. Thermostats can also be used to program different temperatures for different times of the day, allowing you to save energy by programming your thermostat to a lower temperature when you’re not home or asleep.

If there is a blank screen on thermostat or it isn’t working properly, it can be frustrating. But before you call a repairman, there are a few things you can try to fix the problem yourself. With a little troubleshooting, you may be able to get your thermostat working again. Keep reading to learn how to troubleshoot common problems with your thermostat.

Check the batteries.


If your thermostat isn’t working as it should, one of the first things that you should consider is the batteries. There are several styles of thermostats, and while most devices are hardwired into the wall, the majority of them also rely on batteries to power the display screen and some other functions. Most thermostats require AA or AAA batteries, and if they’re low or dead, replacing them will usually solve the problem. You will want to refer to the manufacturer’s instructions for accessing the batteries.

Many people forget about the batteries in their thermostats until something goes wrong, so it’s a good idea to try and install good-quality batteries to ensure they last for several months. You can also put your thermostat on the same schedule as your smoke detectors for checking and changing batteries.

Check the settings.

If you’re having trouble getting your thermostat to work, one thing you can try is checking the settings. You’ll want to make sure the thermostat is in the “on” position and that the power is turned on. If the power is turned on, but the thermostat is in the “off” position, the thermostat won’t work. Ensure you have it set to the correct heating or cooling option and that the fan switch is set to on. If your thermostat is set correctly and is still not working, you can try resetting it by unplugging it from the wall for a few minutes and then plugging it back in.

Clean the thermostat.


If your thermostat isn’t working as it should, there could be dirt and dust built up inside the device. This debris can prevent the wiring from making a good connection with the terminals. As a result, your thermostat could malfunction. Often, the problem can be remedied by simply removing the cover and cleaning it out.

It’s important that you always disconnect the power before you start cleaning inside of the device. You should also endeavor not to damage the wiring while cleaning. Once finished, you can put the cover back on the thermostat and plug it in. If your thermostat is still not working properly after you’ve cleaned it, you might need professional assistance. You’ll want to get in touch with a heating and cooling professional for assistance.

Your HVAC thermostat is crucial to maintaining a comfortable indoor climate. If it’s not working properly, take steps to fix the problem right away. Continuing to use a faulty thermostat can lead to discomfort, high energy bills, and damage to your home. If you can’t troubleshoot the issue yourself, reach out to a qualified HVAC technician for assistance.
