Works fine on shore power. Unit is Dometic 13.5k btu. A new AC should not need hard start. I'll replace the current start cap and see what happens. My gen is more than enough to start the Dometic.
Well, that is where you are wrong. Depending on the AC and the Genset, you need a Hard Start kit. RVP options Hard Start kits for the OEM when they install smaller Gensets on Towables. Dometic does not. IF your unit runs OK on Shore Power but not on your Genset, it is NOT the AC and its capacitors. Your Genset is not capable of the surge current needed without a Hard Start kit. Doug
