Climma Air conditioning Capacitors for Super Maramu

Judy and Bill aboard SV BeBe <yahoogroups@...>


Gary Silver posted the following some time ago:

Each Climma Air Conditioner of the vintage of my boat (SM Hull # 335) has five capacitors as follows:

1 each: 40 microFarads 420 volts to 470 volts (Biggest physical size)

1 each: 10 microFarads 420 volts to 470 volts (Medium size)

2 each: 2 microFarads 450 volts, 50 Hertz (small size)

1 each: 3.15 microFarads 450 volt, 50 Hertz (small size)

The capacitors that failed on my boat (and which I believe are the
run capacitors for the compressor motors) were the 10 microFarad
capacitors. The original ones were cylindrical and measured
3 inches long by 1 and 3/8 inches in diameter and were in a plastic
casing. They had 5/8 inch long spade connectors.

The replacement ones I found were ovoid, in a metal casing,
were larger physically and rated at 600 volts. None of those have
failed but were large enough that they would not fit inside the control box that contained all the other electronic components. I attached them to the outside of the box and insulated the connectors so nobody would take a large shock if they shorted across the terminals.

The only capacitors that have failed were the 10 mfd capacitors. I bought spares of each, but have only had to use the 10 microFarad capacitors.

I just ordered some from (bill's recommendation) (also where I purchase the rebuilt kit for the Calpeda water pump (for Air Condionning as well).
Each unit use 2 (two) capacitator of 2 microFarads and 1 (one) capacitor of 3.15 microFarads
There is also I saw a 40 microFarads and a 10 microFarads (I don't have any information if the last 2 fail often - may be Bill or someone has input on that).
The 3.15 and 2 microFarads were $12 each (the 40 and 10 which were $35 each)

Sincerely, Alexandre

Could you please post or send the capacitor list for the Clima units. I too need to pick up spares before returning to the boat in July.

Oops. Sent that b4 I was done.

I have a list of replacement capacitors and relays if that's what is wrong. It is unlikely that it is the compressor. I had a refrigeration guy tell me I needed a new one, only to find the bad capacitor easily myself.

It's possible that it is a low refrigerant level, but I think you need special equipment to test and replace that. Check the capacitors and relays first. By then you'll have answers from those smarter than I.

Also, check the messages by searching for A/C or Climma. There are several threads about trouble shooting. I think it was Danny on Ocean Pearl who posted some pics in the photos section that are also helpful.

Good luck and let us know what you find.

The aft unit was working very weak, only 2 of the 3 speed (will order some capacitator), and there was a strange smell, I suspect I was loosing the R134a â€" now I don't hear the compressor kicking it at all (only the fan), so it doesn't cool down the cabin at all.

Why does the compressor not kick in anymore? Is this because there is no more R134a refrigerant?

How can I add more R134a refrigerant? I will see if this leaks again (and cool down the cabin again).

The forward unit has all 3 speed working, was extremely cold, so cold there was ice on the coil (of the compressor) â€" but now it seems it can not cool down the forward room… is this because the outside temperature is too high or something else (may be the ice on the coil).

Also, why do I have ice on the coil of that unit (and only that one)?

Thankfully, the salon unit is ok with all 3 speeds.

Thanks in advance, sincerely, Alexandre 713-412-6704
