Dometic RM2553 Refrigerator

Hi Glenn,
Assuming it is perfectly level (they are quite fussy and won't work properly on even a slight tilt) and the flue is clean and clear (check for bugs or cobwebs), then there is a possibility that the gases in the unit have separated. The gases are ammonia, water and a squirt of hydrogen. To fix this, remove the unit and place upside-down for a day or two. Sometimes shaking it around a bit helps as well. This often gets them going by mixing all the gases together again.

Unfortunately, if any gas has escaped (and it's always the hydrogen that goes first), then there's not much you can do. There are some technicians around that fix them, but getting scarce and hard to find.

Good luck
Gerry

Is the freezer working but the cabinet not?
1.If so it is probably the cooling unit.
2.If not the you may have a blokage in the circulatory system which may require removing the fridge turning it upside down to backflush any blockage and hopefully away you go. If not back to stage 1.
You may also have a mudwasp nest of something similar in the exhaust tube.
Have heard and seen some funny things, best thing is with these fridges to keep them running all year round but of course not always possible.

It could be a buggered thermostat. Found the same problem with ours when run on gas.

These fridges do not use normal refirgderator gas but ammonia. You need to run them regularily to keep the ammonia active.

Two months shouldn't make much difference. We leave our 8 YO van o blocks for months without runnng the fridge and t has been fine.

Get a 3 way fridge expert to look at it. That is the only real way you will solve the problem.

There is a Dometic guy on the Caravan forum who helps out on fridge problems.
