I am having an issue with my back AC on my RV. When I plug power into a land line I can only get the front AC to work. When I turn on the back AC all I here is a click. When I plug in the Generator I am able to get both ACs to work. I am also not able to find the circuit breaker for the back AC. Any thoughts as to what could cause this issue?

Do you have a 50amp coach with 2 A/C's it would need the 50amp service that would have the two A/C breakers your looking for

just look at the plug in if it's got 3 prongs then 30amp if it's got 4 prongs then 50 amp

Hi, We have a '96 Adventurer also ours is 30amp. We can only run 1 ac unit (frt. or rear) at one time when hooked up to 30 amp service. I can run both on genny with selector switch( in cabinet above M/W ) in the front position.

When you got the motorhome did both Air conditioners work on shore power or is this a new problem.

This

The second (rear) ac is connected to the genset. Is also why it wont run on shorepower.

So. I confirmed that the plug is a 30 amp plug. I have also confirmed that if i unplug that cord from the RV i can still run the rear AC. That tells me the rear AC is hard wired to the generator. I am thinking further, but cannot confirm that the front/rear switch may allow me to run the rear AC only. So in order to run both AC systems with shore power it would need to be 50amp. Thoughts? A lasso thank you all for the help

Correct on the 50 amp to run rear A/C

30 amp will only run one air conditionerat a time. Choose which one with the selector switch above the microwave. If you want to run both you have two choices: 1) run the generator with the selector switch set to front air. 2) plug into shore power, set the selector switch to front, and run the generator for the rear unit. Sounds crazy, I know but that is the way it is done.

There is a way around it, but it involves putting a plug in for the rear air conditioner and wiring an outlet for that side of the generator that normally powers it. That way you can plug the 30 am plug in to shore power, and run a seperate cord to to another power suppy to power the rear air.
