Have you cleaned the cond. coil? I'd start there. That can cause high compressor amp draw, big time. If you don't have an amp clamp you can skip amping the compressor and use a volt meter to see if the external OL or the internal protector is opening. A dirty cond. coil is enough to cause your problem and if coupled with an underpowered/slow running fan, it will be even worse. At least the OLs still work, if it still cycles. It's hard to find replacements for burnt electric components on those things.
I used to get frequent service calls on rv ACs when I worked in the Az. desert and I could fix most of them... Until the problems were burnt electrical parts. Craig
