The fan on my outside ac unit is not turning on.

SOUNDS LIKE COMPRESSOR IS BURND OUT
CALL A TECH HE WILL PUT METER ON

Either a very bad Capacitor, or the fan belt came loose and the motor is just spinning

TRY TO PUSH OUTSIDE FAN WITH A SMALL STICK IF FAN IS TIRNING ALRADT THE CONTACTOR IS GOING OUT.FAN NOT TURNING STARTUP COMPASITOR IS GOING OUT

Hi!!

This means that the condenser fan motor (outside unit) failed, this caused to build hi pressure and either activated a safety valve to release the extra pressure or blew a line and R22 Refrigerant escaped from system.

The fix is to replace motor fan and capacitor find the leak and refill system with R22 Refrigerant Gas. It is safe to turn on the Fan Only mode on the Thermostat until a HVAC Tech arrives.
To perform this job parts and labor included will cost: about $300 -.$400. Look on the Yellow Pages for a Tech in your neighborhood.

Good Luck!! Don't forget to Rate this post!!

The buzzing noise is probably the fan motor. Is the compressor running? First make sure that there are no tripped breakers. After that kill the power and check the capacitor with a multimeter. If that checks good then check the fan motor windings with the multimeter. Let me know if you have any questions.

It could be the capacitor on the fan motor has gone bad.

The buzzing noise is your contactor drawing in from your thermostat. The fan part of your unit is on a different circuit from your outside A\C unit. Your thermostat is the conductor of the orchestra tying ths units together. It may well be that your A\C circuit breaker has tripped, if it has there is a reason for it's tripping. Resetting the breaker by turning it off then on may get your unit running, but a technician needs to ascertain why it tripped. Or it could be a bad contact switch inside the outside unit not letting enough electricity through the switch. More than likely the first issue. Good Luck

Check the voltage to the contactor coil, it will do that if the voltage is low. This is the 24 volt part.

When ever you hear a buzzing like you are hearing means one thing one of the fuses on the outside disconnect box is bad. Only getting 1/2 the power. Find the bad fuse and get the same size and will be good to go. ken

Time for a new unit. End of sentence.
