How to Troubleshoot Thermostat Problems in AC

Thermostats are important parts of air conditioners (ACs). Without a functioning thermostat, it is not possible to control the temperature inside your home. As such, when the thermostat fails, it can lead to a variety of issues, from minor inconveniences to more serious problems. If you start to experience trouble with your AC, it might be caused by a malfunctioning thermostat. Here we explain the common symptoms of a thermostat issue, so you can troubleshoot your AC.

Signs That You Might Have a Thermostat Problem

The most obvious symptom of a thermostat malfunction is that the air conditioner will not turn on, no matter how much you adjust the temperature setting. Another common sign is that the AC turns on, but then turns off again after a few minutes. You might also notice that the thermostat fails to respond when you adjust the temperature settings.

Troubleshooting Techniques

If you suspect that your thermostat is the source of problems with your air conditioner, the first step is to reset it. If the thermostat is completely unresponsive, it is advisable to switch off the circuit breaker for a few minutes. This action will reset the system and potentially restore the thermostat’s functionality.

If the aforementioned techniques do not solve the issue, it might be because the thermostat is broken and needs to be replaced. The installation of a new thermostat is not a simple task, so it is usually best to call a local HVAC technician to carry out the repair.
