Question

The AC fan in the house has stopped working. It does not turn on any more, not even when I change the fan setting from Auto to On. The AC unit outside the house comes on just fine. Any idea what is going on?

Hello,

It could be the fan itself, or the control relay inside the AHU, or ( Very remote) is the fan relay contact of the thermostat.

If it is the fan itself, It could be the windings, or the capacitor, or the bushings of the fan motor.

You can verify this by going near the AHU and as someone turn on the thermostat, observe if you can hear a humming sound inside the Air Handling.

Thank you! Followed your instructions. There was a humming sound at the fan motor unit. Called an A/C techninician. Problem turned out to be a capcitor.

Incidentally, you need to stop using tech terms such as AHU for average John Q Public. I had to do Google search to find out what it stands for.

Hello,

I am sorry if I used that term. But I am glad you were able to fix your problem.
