Question about Refrigerators
My RM4270 caravan fridge wont work on mains. I've changed the element and thermostat. theres power to the thermostat and to the element feeds but the fridge just dosen't work. it fine on Gas. any sugestions would be appreciated. Kim
See if you have access to a schematic on the unit itself. The fact that it works fine on gas tells you there is nothing wrong with the ammonia solution in the tubing. For that unit to work, the electric heating element has to boil off the ammonia and this is not happening. Check on the schematic if there is some kind of fuse or additional in line switch which is preventing the heating element from turning on and doings its job.

I don't see the need to convert from 110 to 220. If your motor home has 220 circuits then you should be able to have it wired for 110. This would be just like in any residential home. Any 220 generator will have 110 available. 220 is just 2 hot wires, where 110 is one of those same lines and referenced to ground or neutral.
Ask an electrician if you are not sure how to wire it...

The service manual gives the following explanation of your error code (Er FF): "Poor motor, hooking of wires to fan. Contact of structures to Fan. Snapping or short-circuit of L/wire (if there is no fan motor signal for more than 60 seconds in operation of fan motor)" So CoolTech is right!

SOURCE: fridge wont get cold with gas
This is worth a try. Disconect the gas and power make sure the pilot light is out. Turn the fidge unside down overnight then unright again. Try it on gas agian. This worth a couple of goes before giving up.

Some of the Dometics have what was called the 'Dinosaur Board' which is a circuit card which controls the unit.
Not sure if it applies to your exact model, but if there is a company who just makes replacement control boards for Dometic fridges, that is a big fat clue, in my book. Cheers.
