[Amel Yacht Owners] Air conditioning
Thank you for all your answer regarding Air Conditioning!
I will try with capacitors before change the unit.
The most likely cause of the compressor not starting is a bad start or bad run capacitor (or both). This will cause the compressor to fail to start or to run inefficiently and overheat. It may cause the AC circuit breaker to open.
Locate the set of capacitors related to your AC unit (originally in the remotely located electronics box mounted near the compressor). The failed capacitor is usually obvious as it will be ruptured with extrusion of dialectic material. If there isn't an obvious failed capacitor then test them as noted below.
The capacitors related to the Climma Compact 9AC/EH AC units are:
Run Capacitor 40 mfd +/- 5% 420-470 VAC with spade connectors
Start Capacitor 10 mfd 470 VAC spade connectors
Low Fan Speed Capacitor Labeled C1, 3.15 mfd with wire pigtail leads
Medium Fan Speed Capacitor Labeled C2, 2 mfd with wire pigtail leads
Fan Run Capacitor Labeled CM, 2 mfd with wire pigtail leads
All capacitors fail with age and operating conditions. You can test the capacitors (test them out of circuit by disconnecting each one at a time) using a multimeter with capacitance functionality. CAUTION -ASSURE POWER IS DISCONNECTED FROM THE UNIT AS THESE ARE LETHAL 220 VOLT AC UNITS AND ALLOW 30 MINUTES OR SO AFTER DISCONNECTING THE POWER TO ALLOW THE CAPACITOR CHARGE TO DISSIPATE (unless you know how to discharge them) PRIOR TO WORKING ON THE UNTIS. Something as cheap as this:
Capacitors of the the proper rating, dimensions, and connection configuration are obtainable by searching on the internet. One good site I have found for capacitors with pigtail leads is:
The compressors will NOT fail by running on 50 or 60 hertz and the compressor is probably the most bullet proof item on the Climma AC units.
Good luck and let us know what you find out.

My compressors on Kimberlite have been working fine on 60 hertz for the last 15 summers and much of the winter in the Caribbean.
Unfortunately I have tried to use a number of “certified” Climma technicians on St Maarten and many do not know what they are doing and one firm near the bridge is absolutely dishonest.
I would wait till you find someone on another island. Possibly write to Coastal Climate Control info@...
They are the USA distributors for Climma. They are very honest and knowledgeable. They might recommend a technician.
Did cleaning your propeller make your boat run faster?
Thank you for the kind note.

Ps if you are still in St Maarten I arrive on June 22 and can help you with your Climma problem.

The air conditioner of the bow doesn´t work. When it turn on, the fuses fall all over the boat.
The air conditioning technician pointed out that the bow equipment, a Climma, Compact 9 EH, has bad the compressor. The compressor must be replaced. He says that compresor is 50hz and when used it with an electric current of 60 some of them can deteriorate. Any suggestions to replace for other equipment o replace the compressor?
