Rear AC won’t turn on after I change selector to rear AC
I just purchased a 1994 33’ Holiday Rambler RV. It’s a fixer-upper and I’m hard at it setting the old gurl right. I’ve worked over 3 fixer-upper power boats so I’m not a complete virgin at this sort of thing. Unfortunately, though I’m very handy, there are some systems that I’m a bit inexperienced working on, hence my question about my RV’s 2 AC units.
The rig has a 30 amp system and as I understand it, you can only run one of the roof top AC’s at a time, unless you’re running on generator power. However, you can run both AC’s at once using the onboard generator. Here’s the problem:
When hooked up to an AC power source (my house), the front AC works fine. However, when you switch to rear AC only (using the selector switch) the rear AC won’t turn on.
However, both AC’s will turn on and run if their power is from the onboard generator (so I suspect the problem isn’t in the AC).
I’m guessing the problem is in the selector switch, though it appeared to work fine with the generator power. Before I tear into things, has anyone here had a similar problem and if so what caused it?
Thanks in advance for any insight given to solving this mystery.
