12,000 BTU Cruiseair, about 6 years old, flips circuit breaker after about 30 secs. Compressor starts, then amps go to about 10 and start to drop to about 3, then the amps surge and flip the breaker. Any idesa?

Sounds like the unit is not getting seawater, then shuts down on Hi pressure, then tries to restart against that pressure & trips the breaker….

See  http://marine-ac.com/2009/08/1…..re-switch/  for more explanation.

Your description is a very typical problem/scenario with lack of seawater flow.

Dear Steve,

Thanks! I'll check it out and flush the sea water system.
