2013 361REQS Living Rm AC Problem

So we are parked in front of the house cleaning out the 5ver after the Memorial Day camping trip. I have the on board generator running and the living room AC cooling while we work.

The wife starts to slide in the Drivers side living room slideout and the AC quits. Cant get the AC to do anything now, not even just turn the fan. Power to the thermostat seems fine, it displays temp. Slide out still works fine.

I checked the breaker and it is not tripped, I reset it just in case. No change. Popped off the thermostat front and notice one of those glass fuses on the circuit board. Its not blown, just in case I remove it and the thermostat goes out. So I know its good.

I haven't been near shore power to determine if its a generator problem or AC problem, but the bedroom AC works fine and the other electrical items (microwave for example) work fine when generator is running.

So finally to the questions:

Will/should the LR AC run with the slidouts in?
Is there a fuse, breaker, reset switch in the AC unit itself that may have tripped?
What else could it be?

My assumption is that the combined load of the AC and the slide out motor overloaded something in the AC. But that kind of doesn't make sense as the AC should be running 120 from the generator and the slide out should be running 12v from the batteries. Right?

My wife's assumption is that the AC can't run with the slide out in.

I'm about to break into the AC manual, as I didn't find anything in the trailer book. But wanted to post this here in the event that I dont find anything.

Does it start running when the slide is back out? I don't know of any restriction on running ac while slide is in. I have done it a few times and had no problems but I was on shore power.

Any way to test it with shore power?

Trailer is at the storage facility and I can't put the slides out without hooking up and pulling it out of its space.

We planned a short weekend trip this weekend at a place about an hour away. I was trying to eliminate as many possible problems as I can while its in storage, then if all else fails I will have it in a place this weekend where I can connect to shore power and have the slides out.

Problem is, if I can't get it to work while we are there then we will be camping in 90+ degree heat all weekend...the bedroom AC will be working overtime.

You may not have any other options until you can open the slide or get some shore power to answer a few questions.

My next question is what size genny do you have and do you normally have the capacity to power both ac's?

True story.

In the AC manual it mentions that if you have good power to the AC unit then to check some sort of connector on top of the control box in the AC unit. I'll run over and check that tomorrow if I can wiggle my rear back there with the slides closed.

Its an Onan 5500, and should be enough to power both ACs. At the time of the failure, the only things drawing power were the LR AC, the slide motor and the kitchen lights.

There are two breakers on the geny, one may have tripped so you are only getting power to 1 side of the breaker panel.

Grumpy is the winner. Ran over and checked this afternoon and one of the two breakers on the genny was tripped. Dont know why I didn't even think about the generator having breakers on board.

Everything seems to work fine now.

Thanks for the advice.
