Coleman 8534D Heat Pump-Gen Surges Cliff 6-16-17  
I have the Mach 8534D8796. With 5500 generator running, the front air conditioner causes the generator to surge about every 30-45 seconds and the amps increase to 48-58. It continuously goes through that cycle. The rear unit works just fine. Maybe one of the compactors? Thanks...

I doubt the AC is cooling.

I bet the Compressor is seized solid and the AC needs replacing.

The 48 amp draw is the compressor trying to start and the overload tripping out.

Good Luck

Figured it out. Found the start hard start capacitor to be bad...actually burned the wire off. Replaced and working fine.
