Re: [Amel Yacht Owners] Aft Cabin Air Conditioning Tripping 220 Volt Panel Fuse & marina

My suggestion is to buy a multi-tester that will check capacitors.
Inside the Climma Compact Control Box are 5 capacitors. Three of these are Fan Speed Capacitors...they are the smallest of the 5 and are normally strapped together. You will see these three first, before digging deeper to find the next two. If it is a capacitor, it is likely the next two.
If you cannot get a tester, replace these two. Here is a previous post from Gary Silver
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.
