How To Troubleshoot Your Air Conditioner Thermostat?

The thermostat is a primary component of your air conditioner. And if something went wrong or if it’s not installed properly, then chances are this device would not function the way it’s intended to be.

However, not all thermostat issues require the help of a technician for there are some troubleshooting steps that you can do on your own before calling an HVAC expert. So read more as we are going to share some DIY information on how to troubleshoot your air conditioner thermostat in today’s guide.

 

Things That You Need To Check When Performing A Thermostat Troubleshooting Process

Before considering the services of a professional, you need to check on these things first:

Is The Device Receiving Power?

If the air conditioner thermostat is always shutting down or the backlight keeps turning off, the first thing you need to do is to check if the device is receiving enough power. Thermostats are powered by batteries and your AC itself. So you need to ensure that there is enough power coming from these sources.

Likewise, you also need to check if the circuit breaker has tripped, which also causes the device and the whole air conditioning unit to lose power. We also recommend that you change the batteries and replace them with a fresh set.

Is The Thermostat Situated Near Sources Of Warm And Cold Air?thermostat installation

If the device is installed in very cold or warm areas, then it won’t be able to make an accurate reading of the temperature in your home. And as a result, it won’t be able to activate when cooled air is needed inside the house. So make it a point that the thermostat is installed in areas away from windows, vents, direct sunlight, and any other factors that might influence the temperature around the house.

Is The Device Properly Mounted On The Wall?

Proper installation is also necessary for the device to function well. If not, then it will only give you faulty readings which can then result in waste of energy (as reflected in your monthly electric bill).

So try to use a bubble level and check if the thermostat is properly mounted on the wall. Also, make sure that it is installed at least 5 feet from the floor to ensure accurate readings at all times.

Is The Thermostat Dirty?

And one last thing that you need to check is if the AC is dirty because any dirt buildup in your cooling system can also cause the air conditioner thermostat to malfunction. So clean up your AC unit by opening the cover and remove any dirt that you can find.

  1. Check whether the thermostat s display is lit. If it is not, the thermostat cannot signal the air conditioner to cycle on. Look for and address simple reasons why the thermostat isn t getting power, such as dead batteries or a tripped breaker or blown fuse in your main electrical service panel.

  2. When thermostat problems develop, they are rarely dramatic events with sparks flying, or where smoke alarms sound. Most thermostat malfunctions cause subtle or sudden changes in the performance of your cooling system. Since the system s functionality is affected, it is easy to misinterpret the symptoms as urgent HVAC equipment troubles when a simple fix at the thermostat may be all that is needed.

  3. That’s a good point hat he thermostat would have to be properly installed to make sure that it works properly. I could see how having it not connected to the air conditioning, then I could see how it would have a hard time telling it when to turn off and on. I should make sure that I have someone take a look at the thermostat as well if I decide to get a new air conditioner, so I can be sure it’s all hooked up properly.
