The fridge works fine on ehu and gas but when travelling and I switch it over to battery it doesn't appear to be working ('cos the blue light is flashing). I have tried only switching it over when the engine is running and I've also tried turning the temperature down just in case it's trying to tell me that it can't reach the top cooling setting on battery, but neither makes any difference. Can anyone suggest what the problem might be? We are fairly new to motorhoming and not very tech/mech minded so there might be a fairly obvious answer that we're not aware of. This is urgent because by the time we arrive on site there is no ice for my vodka!
Many thanks.

Sounds like the fridge is not getting a 12v supply whilst engine is running , most likely a blown fuse or a failed relay,

The manual says you must check your fuse and 12 volt supply.
If that fails its a workshop job but I suspect it might be the 12v element. We have had one go on ours.:Sad:

many many years! since I was a kid
check the simplest and cheapest points first. is the relay cutting in and supplying 12v? if not is the fuse blown?

good fuse but no 12v at the fridge would be a relay or connector fault.

relay is only around £5 so check and change this. its always good to have a spare as they do burn out

if youve got 12v to the fridge from the battery (not the control line) then it may well be the 12v element. it starts getting complicated from here on, but you should have a fault code

Hi
I might be sounding a bit daft here :Doh:, Is your's an Auto or Manual turn over, if so is it changing on Auto or are you changing it on Manual, just a thought. Pete :thumb:
