Question about Dometic Rooftop RV Air Conditioner
You have a faulty start capacitor. The capicitor helps start the motor ... since it is not doing its job, the motor draws LOTS more power from the line popping the breaker. Have your professional RV service center service your AC.

Testimonial: "I am a technical Instructor for a major import, so I know my way around HVAC. so glad to have someone who can pin point the problem I found that the motor start fuse on top of the capacitor is melted. it still has some continuity, but looks like your diagnosis will fix it."
Hi, just some food for thought, it is a run capacitor, not a start. The capacitor has a resister across it that has over heated. The first thing to check would be the capacitor, but if the compressor is drawing enough amperage to kill the generator, I would also mega ohm the compressor windings as this may also cause this problem. Some older compressors had the start capacitor, then they added a run so the start would drop out when the compressor got up to speed. Now, they did away with most all start capacitors except on refrigeration equip. They use both single and dual capacitors on a/c units. Good answer though.
