If your air conditioner turns on but you don't feel any cool air, the condenser fan may not be working. This could be due to a simple issue or something that requires a hefty repair. Here are five common reasons why your AC condenser fan isn't functioning.
5 Reasons Your AC Condenser Fan Isn't Working
Air filter blockage
If you don't clean or change out your air filters often, or if you skip out on annual air conditioning maintenance, your filters will likely get dirty and clogged. Not only will this negatively affect your indoor air quality, but it will also put more stress on the fan and possibly cause it to shut down. Keeping your filters clean will prevent this from happening.
Power issues
The circuit breaker can sometimes get tripped from overheating due to outside temperatures, which will cause your HVAC fan to stop working. Flipping the switch at the circuit breaker should fix this issue. Some units may have a shutoff on the unit's side, so you should double check that this hasn't been switched off, too.
Dead capacitor
A capacitor is a small, but important component of an air conditioner that stores electrical energy and provides it to the system when required. There are several capacitors in an air conditioner. If the capacitor responsible for sending energy to the fan motor is dead, the HVAC fan won't turn on. If this is the case, you will need to get the capacitor replaced.
Burnt-out motor
Fan motors can get overworked and stop functioning if you don't keep up with maintenance. Fan motor repair or condenser replacement by a professional HVAC contractor will solve this issue. Oftentimes, full replacement is recommended since repairs can be costly.
Dysfunctional contactor
The contactor is responsible for controlling the electricity flow throughout the unit. Over time, this component can wear down and burn out, causing the condenser unit fan to stop working. Repairs can be done in the event that the contactor stops working. To avoid this from occurring, keep up with AC maintenance.
