Central air conditioner outside unit fan is not running.
Shut off the power supply to the air conditioner at the disconnect or breaker panel.

Understanding the parts of your ac unit.
Inside your air conditioning unit the fans turn with the assistance of motors and capacitors.
So you do some investigating and realize that even though the outside unit is buzzing the fan isn t spinning.
A blocked air filter may be the culprit in why your air conditioning s fan is not spinning.
Fans in the central a c both pull air out of the room to be conditioned and have humidity removed and also push chilled air through the vents throughout the house.
While each component in a central air conditioner is critical quite simply the unit will not work if the fan is not running.
When your air conditioner s filter is dirty filthy and clogged air flow can t go through the filter and ice will begin to accumulate on it.
If the ac fan won t spin the entire unit is functioning inefficiently or not at.
Its job is to cause motion and that motion moves the air.
You can think of the motor on a fan just like the motor in your car.
As a result this puts more stress on your unit s fan as well as the other parts of the machine.
Do not proceed if you re not sure you ve properly shut off the power.
