The fan is an essential component in the air conditioning system. Its function is to move air through the evaporator to distribute cool air throughout the room.
If the fan stops working, the unit may lose efficiency or fail to cool properly.
Common Causes of Fan Failure
There are several reasons why the fan may stop working.
Electrical Problems:
An interruption in the power supply can prevent the fan from activating. It is recommended to check:
- The plug.
- The circuit breaker.
- The thermostat settings.
Dust Accumulation:
Dirt can affect the movement of the fan blades. Regular cleaning of filters and components helps keep the system running properly.
Damaged Capacitor:
The capacitor helps the fan motor start. If this component fails, the fan may not rotate. Replacing a capacitor usually costs between $20 and $60, depending on the model.
When to Call a Specialized Technician
If the fan does not work after checking these basic aspects, the problem may lie in the motor or the appliance’s electronic board.
A specialized technician can perform electrical tests and determine whether any parts need to be replaced.
