I had a similar problem on a different make of fridge. The compressor
was actually a 12 or 24v unit with a converter to take 110 to 12. When I bypassed the converter and took 12v straight to the compressor
it worked fine. The problem was in the converter, voltage was getting through but not enough amps to run the fridge. It was the 2nd converter or the unit because I had a similar problem with the first. The 2nd failed in Bahamas
, so I now just run it as 12 volt and it works great. When on shore power
, the battery charger
keeps up fine.
FWIW I have a freezer
with the same converter that has worked trouble free for 2 years.
Assuming yours is similar, try bypassing the voltage converter and see if it runs OK.
