Question about Dometic Rooftop RV Air Conditioner
My Dometic AC has trouble starting after it has inactive for a month or more. The fan will run, but the compressor will not fully start. It hums momentarily then stops repeating every two minutes or so. This will continue for up to an hour until it finally starts. There is a hot electrical smell while this is going on too. Once the compressor finally kicks over, it runs fine for the entire trip until it is shut down for another month or so. Is this a weak start capacitor or a bad compressor?
Thanks for the help,
Sounds like your compressor is actually bad. if it was a capacitor, it would have either already burned up which you would smell smoke and you might see it come out of the vent and the compressor would no longer function, or the capacitor is completely dead. They don't always explode or burn up, sometimes they just short out internally.
the other question with the generator. you need a hard start capacitor kit. they come with a start delay relay and don't cost very much. it will prolong the life of the compressor and they are very easy to install.

Just add a$10:00 hard start kit to the compressor.
