No power to Rear Roof Air Conditioner

jbragg · February 08, 2015, 10:11 AM

Rear A/C unit not working. No power at the unit itself. Already checked breaker and it is good. 122 volts at breaker. I know the problem is the unit is not getting power, but not sure where to start troubleshooting. Not sure if wires go directly to unit or if there is a junction somewhere between unit and breaker. Other question; if it turns out to be a bad feed how hard is it to change out?

122 into and out of the breaker?

I recall something about a switch that won't allow both units to run at the same time on some MHs. I was looking at 92 Chieftain and I believe that's where I saw that. I'm not sure if yours has that switch or not, do you have wire diagrams for the MH?

I don't have a wiring diagram. There is switch under the refrigerator, but that is the only switch I know of. And there is good voltage coming in as well as out of breaker.

There is a selector switch to choose front or rear air . You can only run both at the same time on the generator . My switch was in booth seat.

The wire diagrams for my 86 are not posted on the Winnebago website, so I made a couple phone calls to them and got all the diagrams for wiring, plumbing and coach construction from them. They were very nice people to deal with as well and it was free, they emailed it all to me.

Thanks everyone for all the good info. After further investigation there was a switch below the refrigerator that switched between the front and back AC units. Bnova I'm going to get in touch with Winnebago And get all the diagrams sent to me. Appreciate all the help. I'm sure before we get to take our maiden I'm going to have a million more questions. D:oH!
