Your air conditioner should stop running when the temperature you set has been reached. However, if it starts running continuously without turning off, it is usually due to a problem somewhere. There are several reasons why your air conditioner would fail to turn off. Knowing the culprit behind the problem will often help you know the kind of repairs you need to make. Therefore, here are a few troubleshooting tips for an air conditioning system that won’t turn off.

 Check the Thermostat

The thermostat is one of the key components of an air conditioning system. It works by monitoring the temperature of the air inside your home, and if it rises above what you set, it will activate a switch that in turn powers the air conditioning system. Therefore, an incorrectly set or defective thermostat can be the reason your air conditioner runs continuously. Unless the thermostat is visibly damaged, identifying a faulty thermostat may not be straightforward. If you have some basic knowledge of electricity and electronics, you can use a multimeter to check for the thermostat’s continuity. You may have to replace the thermostat if it lacks continuity. The best way to determine whether or not the thermostat is faulty is to have an air conditioner technician inspect it.

 Check the Condenser Coils

The work of the condenser coils is to disperse heat as the refrigerant passes through them. Over time, debris and other dirt may build up on these coils. Dirty coils will impede the cooling process and make your air conditioner work harder to cool your home by running continuously. Therefore, inspect the condenser coils for dirt and build-up of debris and make sure you clean them. Also, remember to clean the coils periodically to prevent the problem from recurring.

 Check the Air Filters

Air flow is essential for the proper functioning of your air conditioning system, which is where air filters come in. Dirty and clogged air filters will restrict the flow of air, affecting the entire cooling process. Your air conditioner will then have to struggle to cool your home, which means it won’t turn off. Therefore, check your air filters and clean or replace them if they are dirty. Similar to condenser coils, plan for routine cleaning or replacement of the air filters.

A continuously running air conditioning system can leave you with very high energy bills at the end of the month. Therefore, make sure you contact an air conditioner technician as soon as possible to make the repairs that you cannot do yourself.
