I just bought a '85 winnie and the roof air unit sounds like it has a hard time starting. the breaker pops after about 2-3 minutes. there seems to be a big drain on both the onan and the shore power plug as the fans slow down a lot when the compressor tries to start... when it finally gets running.. the air is ice cold. but it only runs 2-3 minutes and then the breaker pops. capacitors?? compressor?? or too little of extension to shore power. from rv to outlet about 14 2 wire..

Sounds as if the capacitor-start compressor motor isn't coming up to speed---not fast enough to open the contacts and cut the power demand---, or the contacts won't open, even though the motor does come up to speed. That would mean your 19.5 or so AC would be drawing 2-3 times that amount until the breaker popped.

Or you could have the bearings going out in the fan motor. If the air is ice cold, your compressor is prob running, but the fan motor may be drawing too many amps. I just changed ours for this reason. Easy to do, about 20 minutes work. Check it with an amp meter first to see what is drawing too much. STeve
