A/C motor problem??????? jim 10-15-08  
I'm having this weird problem.

Sometimes the A/C & Fan doesn't work.

I can hear the A/C compressor kick on when on A/C.

I can hear the motor hum when just on Fan.

So far this has only happened in the drive way - hooked up to a 120v, 20AMP with a 10 foot extension cord.

I know that could keep the A/C from working, but when it works, even it the drive way, it's works fine.

I had this to the dealer for a week, they could not reproduce the problem.

I know that is low AMP for the A/C, but it seems like the fan should work no matter what?

As mentioned, I car hear the fan motor and A/C compressor hum. So, the switch is good and I don't 'think' power is the issue. The last time this happened, I got on top my rig and checked the fan (made sure it turned), and it seemed fine too.

Now I might get up in the morning and check it again, and it might just start working.

Any ideas?

Sounds like a low voltage problem. Check with voltage meter at motor and compresser.If 220v,could be single phaseing ( 110 volts)

Could be a dead spot on the fan, I have also seen a wasp nest that would stop a fan from starting only when the coach was parked at a certan angle. But more thank likly there is a voltage problem or faulty contact in the control relay. good luck
