Why Is My AC Thermostat Not Working?

Have you ever woken up in the middle of the night to the realization that your air conditioner’s thermostat isn’t working? It can be disconcerting, to say the least. Nobody likes the sensation of being too hot or too cold in their own home. Fortunately, you can take steps to repair your thermostat—or even just identify the problem with it.

It can be difficult to troubleshoot why your AC’s thermostat isn’t working properly. Even though they may look simple on the outside, a myriad of components work together to make sure your thermostat functions properly. From the power source to the sensors, there are many potential causes of thermostat failure.

To identify and fix the problem, it’s important to first assess the situation. To do that, you need to observe the thermostat and see what is happening.

Checking the Power Source

The first thing to do is check on the power source of your air conditioning system. If the power supply is not directed at the thermostat, the system won’t have an ample amount of energy to keep up with the demand of your environment. Make sure the circuit is powered on and that the main electricity switch is energized.

If the electricity switch is off, leave it off for a couple of seconds and then turn it back on. This may reset the system and bring the thermostat back to life. If this doesn’t work, you may have to call an expert.

Inspect the Sensor

The next step is to check if the sensor within the thermostat is working correctly. When the environment’s temperature surpasses the sensor’s threshold, the device will kick on and regulate the air conditioner. A dusty environment can block the sensor and prevent it from delivering accurate readings.

To clean the sensor, simply use a fine brush to remove any dirt or dust particles. You should also remember to clean the other parts of the thermostat for the best results. After the cleaning is complete, wait for a few minutes to see if the system begins to regulate the temperature.

Restoring Your Thermostat

At this point, you should consider calling a local, reliable appliance repair service. Depending on the complexity of the problem, it can be better to leave the task to an experienced technician. Other issues to look out for include inaccurate calibration, wiring issues, corroded batteries, and other potential causes.

If everything checks out, you may have to replace your thermostat. There are plenty of thermostat models on the market, and some of them come with the capability to measure humidity and store the readings in an internal memory.

By investing in the right thermostat and having a certified HVAC professional install it, you can maximize the efficiency of your air conditioning system. This saves you money and increases the comfort of your home.

In Conclusion

If your AC’s thermostat isn’t working and needs to be fixed, the first step is to check the power source of your air conditioner. After that, you should inspect the sensor for dirt and dust buildup and clean it if needed. If the problem persists, you should contact a reliable appliance repair service.

Air conditioners can be complex systems, so it may be best to leave the work to the professionals. They can reach the root of the problem and help you restore the thermostat’s functionality.
