A/C not working, draws high amps and shuts off

07 HR Endeavor,40PLQ.
My forward a/c unit draws a bunch of amps when compressor tries to kick on, generator revs up and then returns to idle.
According to amp meter on control panel, goes from 9 to 69.
Rear unit is working fine.
What could be the problem?

It sounds like your air conditioner motor is working real hard with high amp readings. Sounds like mechanical failure inside the compressor that is causing the motor to over amp/trip. Sounds like it is time for a new unit.

Sounds like locked rotor amps. Either there is a mechanical problem with the compressor or the start compactor is bad or if it has one the start relay is bad. The last two will cause motor to draw high current because it does not have enough starting torque to get the compressor running. Been many years since I worked them, the compressors use to have a data tag on them that showed the locked rotor amps.

Hi mpfleet,
Consider starting with the cheap parts first. There are two start capacitors in the starting circuit. Make sure both of them are functioning correctly. If you are a DIY person, one can take off the protective covers and look at the capacitors. Most of the time, but not always, a defective capacitor will have fluid residue visible. It may even be melted.
