I have a campervan with a 12 volt 110 litre compressor fridge installed. We have recently installed 2 x 250 watt solar panels so we know we have enough power, however the fridge never seems to shut off. The ice box works and keeps things frozen, and the fridge stays at a constant temperature and stays cold but not frozen, however the fridge keeps running constantly 24 hours. We have the temperature knob set about half way around. When the fridge has been running for several hours, we can turn the temperature gauge knob inside the fridge back slightly and it will shut off. Is this normal for one of these fridges? Also, how would one go about testing the thermostat to see if that is the problem, apart from travelling 100 miles to a technician? Is there anyone out there who can shed any light? Cheers Grant
How full is the fridge and when did you do a defrost cycle like most normal 230 volt fridges by default.?
Others have found some 12 Volt compressor fridges also need a defrost cycle about every 3 months app.
