A broken AC thermostat is one of the biggest issues a homeowner can face during the hot summer months. It can cause your home to get uncomfortably cold or hot temperatures. A broken thermostat leads to significant use of energy and you end up paying higher energy bills.

If the thermostat is non-responsive or if the display is off, it means the thermostat has problems or broken. Likewise, if the AC system is not cooling the room, again, it is a sign of a broken AC thermostat.

Generally, any time the air conditioning system does not deliver the cooling or maintain the desired temperature, it means you have a broken thermostat. A similar issue can occur if the system itself has issues—for example, leaky ductwork.

Want to know how to fix your AC thermostat? In this article, we will answer this question that will help you fix the broken AC thermostat. Read on!

Common Thermostat Problems

AC running continuously: If you have noticed that the AC runs all the time despite you have turned it off, this is a clear sign of a broken AC thermostat. A wiring issue may cause this problem. This requires you to recalibrate the thermostat so that it gives the correct instructions to the AC.

AC not turning on: This is another sign of a broken thermostat. Most often, a wiring issue leads to this problem. Call an AC service so that the technician can accurately diagnose the problem. Malfunctions in the internal temperature measuring instruments may also cause this problem.

Temperature Fluctuations: Do you freeze in the bedroom and sweat by spending only five minutes in the kitchen? When temperature varies from one room to another, this is the most obvious sign that something is wrong with the thermostat. Again, you may need to call a repair service. They will send a technician who knows exactly how to fix ac thermostat.

No Power to the AC Thermostat: Another definite sign of a broken AC thermostat is not receiving power. When the thermostat does not receive power, it does not turn at all. An unlit backlight on the thermostat display also means a lack of power.
