How To Troubleshoot And Fix A Non-Working Air Conditioner Fan

Air conditioners are essential to keep your home cool during the hot summer months. However, what you do not want to encounter is the air conditioner's fan not working. Without the fan, the AC unit won't be able to blow out cool air. Not only is it frustrating, but it can also lead to higher electricity bills, and worst of all, it could damage your air conditioning unit. Here are some common causes of the air conditioner fan not working and what can be done to fix it.

Check the Power Supply

The first thing you should do is check the power supply. Your AC unit may have blown a fuse, which could be preventing the fan from working correctly. Try turning off the air conditioning unit, and then turn off the circuit breaker or fuse that powers it. Wait for a few minutes, and then turn the circuit breaker/fuse back on and switch the AC unit back on. If the fan now turns on, then the issue was either a tripped circuit breaker or a blown fuse.

Check the Capacitor 

The capacitor is a small cylindrical part that provides a boost of power to the motor. If it's malfunctioning or not working correctly, it will prevent the fan blades from turning. The capacitor needs to be diagnosed and tested by a professional. Therefore, it's best to call a trusted AC repair service provider near you to help fix this issue.

Clean the Air Filters 

If the air conditioner's filters become clogged, it can reduce the air circulation. This may cause the fan unit to overheat and turn off. Ensure your air filters are cleaned regularly so that the airflow is not hindered. Also, inspect your ductwork for any obstructions that may restrict the airflow of your AC unit.

Check the Fan Belt 

Your air conditioner has a belt that connects the fan motor to the fan. If it becomes loose or worn, it will stop the fan from running correctly. Check your fan belt for indications of wear. If it looks worn or is loose, tighten it or replace it with a new one.

Call a Professional 

If you have tried all the above DIY methods, and your air conditioner fan still isn't working, then it's best to call a professional HVAC technician. They will have the necessary tools and expertise to diagnose and repair the issue.
