Iv finally got the thing out its housing, took a ruddy age to work out how it comes out....
Removed 4 screws and the flew from the rear as suggested on a caravan repair site, brute force won in the end LOL
Its a Thetford fridge (caravan is 2007 Swift Charisma 540 6 berth)...
Iv turned the fridge upside down, will be refitting it in about 20 mins...
All three connections have been tested, 240V is OK - 12V is OK and also the gas is OK (propane
)
Will see what happens tomorrow, or maybe even later on tonight... it usually gets cold inside enough for the veins inside the fridge to get wet....
It is as said above an evaporator type, no motor = no noise at night time so I get some sleep.... LOL
Hopefully the turning upside down trick will sort it, if not then I'll get the coolbox running and start saving up me pennies....
