Re: Climma Compact 9 EH MK3 Air Conditioning

Hi Bill,


This is the new Climma unit. It is about 4 years old. I replaced a non-Climma unit with this to get back to the original band of parts.


The wire harness has a Blue and White wire that connects to the remote circuit board.. This powers the compressor. When I disconnect this, the unit will power but obviously the compressor doesn’t run.


The start capacitor checks out. I think it would only pop the GF breaker when the compressor tries to start if this were bad. But it pops immediately when power is applied to the unit.

The run capacitor checks out. I completely disconnected it and still got a GF trip.

The connections are all very clean and no corrosion.


I think the only thing left is a fault or short inside the compressor.




With best regards,

Wasn't that the unit you replaced with non-Climma?


None of this will likely help because it is likely the compressor has an internal short.


If it is not Climma, I am not sure how the electrical connection to the compressor is made, but that connection should be checked closely. What about start and run capacitors? Are they in tolerance and are the connections free of any corrosion?

Hi Mark


May be it is a similar problem as with a waterheater when the heater is corroded and the phase and the zero conductor comes at certain point together. I am not sure with that.

Rats! It’s hot as heck here in Panama and my aft AC has decided not to play.


This morning, the main GF breaker popped. By turning on breakers one at a time, I was able to determine I have a GF in the aft AC unit. The AC unit immediately pops the GF breaker when powered on.


I have isolated the fault to the compressor. If I disconnect the compressor power from the main circuit board everything else works. The board powers up, the fan turns on etc. The moment I connect the compressor power, the boat’s main GF breaker pops.


Any thoughts?
