How do I know if my compressor fan motor is bad?
5 Signs That Indicate a Failing AC Fan Motor
- The fan won’t start even though the AC is on.
- The fan continues to run, even when shutting off the AC.
- The fan is on but rotating very slowly.
- The fan runs intermittently.
- There’s a rattling or buzzing noise coming from the condenser unit when the fan is turned on.
Why is my AC compressor not working but the fan is running?
When the fan is running but the AC compressor isn’t there’s a good chance that electrical power isn’t reaching the outside unit where the compressor is located – and since the inside unit has power, the fan is still operating. First, check the circuit breaker to see if it has tripped or if there’s a blown fuse.
How can I tell if my condenser fan is running?
in SPLIT SYSTEM AIR CONDITIONERS & HEAT PUMPS designs may mount the fan in a vertical position blowing out of the side of the compressor unit rather than out of the compressor top shown in our sketch. If the condenser fan is running you will see the fan blade spinning at speed (typically at 1725 rpm) and you will feel air blowing out of the unit.
Where is the fan on an outdoor compressor?
The condenser fan is visible inside of the outdoor compressor/condenser unit such as the unit shown in our sketch at left, an in our other photos on this page. Our central A.C. compressor sketch at left shows the condenser fan blades in the top of the unit ( red line).
Why is my outdoor AC unit’s fan not spinning?
Scenario A: You hear the outdoor unit’s compressor working and the fan isn’t spinning. Scenario B: You don’t hear the outdoor unit’s compressor working and the fan isn’t spinning. Let’s explore both. Not interested in being an HVAC sleuth?
