Speaking of AC ??"Is my motor home haunted ?"

Speaking of AC?
So while plugged in to the AC 120 volt 20amp
my rear ac (only while walking in the unit) seams like the compressor starts but not the fan and here is the kicker is that the switch on the controller is on off ?????the front ac is fine ???
So the question is "Is my motor home haunted ?"

If you are plugged into a 20 amp circuit, there is NOT ENOUGH AMPERAGE to run 2 A/C units....actually, barely enough to run one and your converter!!

This is probably why you can't get the rear A/C to run and attempting to do so on such a lite circuit could cause permanent damage to the rear unit. If you are set up for a 50 amp circiut (and NOT 30 amps) at thecoach, you will be able to run both A/C units together......but not on 30 amps and DEFINITELY not on 20 amps!

Depending on the size of your enerator, you might be able to run both....but it should be at least 5KW.

Actually what I am saying is that the compressor starts by it self
I am NOT trying to run the AC or fan front or rear
It seams the compressor starts by it self but no fan - with everything on off
I talked to some one up here and they think it might be a bad relay that is sending a signal to the compressor by just movement (ex by walking around in it)I am no expert on electrical so does this sound right ?????????

That's a little clearer!

What type of A/C units do you have, and from what year?

Since they always have 120VAC and 12VDC to them, a bad relay or thermostat might do just what you describe. You can probably have the relay control board replaced if it is defective!

If that doesn't work, then Father Flannigan might be your only hope!
