We've just returned from a fantastic 3 week break down in the Cotswolds. For the first 10 days, our fridge was working perfectly off the EHU. However, one evening we returned to the caravan to find everything in the icebox had defrosted and the rest of the fridge like an oven. The fridge light was working and the switch was showing the power was getting through from the mains. I switched the fridge over to gas and it worked perfectly from then on. When we returned home i switched the fridge over to run from the 12v connection but on arriving back home, the fridge was warming up again. It seems strange (to me at least! : that the fridge will work perfectly weel on gas, but not on electricity. Has anyone any idea what could possibly have gone wrong or do you reckon it will take an engineer to sort out this one?
