Has any body out there replaced the thermostat in their Dometic RM 2553?!
If so could you please let me know how you did it.
I have the replacement thermostat and I am not near a township at this point in time to trot into a refrigeration workshop and I really don't want to pack up and then reset up later if there is a refrigeration mechanic in town.
Any genuine help will be appreciated.
Best Regards

Had to replace the 240volt heating element in ours a couple of weeks ago in the field. Could get to that from the outside bottom vent, bit difficult but do able.
Not sure if you may need to take fridge out to do thermostat. Can not remember if you can see themostat switch from outside vents.
Our fridge would only work on 12volt and gas, no thermostat on those two systems, only on 240volt. New element had it working again as new.
Wiring diagram was on fridge at bottom vent hope this may help.

Hope all goes well in your replacement.

Hi Beware there is 240 volts on the thermostat terminals! I replaced mine in January myself. There are two different types of thermostats. One with screw in gas fittings and one with push in plug type. Mine was the screw in type.
I am no brain surgeon but managed to swap it over without too much effort. I did pull the fridge out to access the thermostat and run the sensor tube down the back without damaging it. Beware there is 240 volts on the thermostat terminals!I will not give any advice on the electrical connections. However make sure you unplug the caravan from the mains before you attempt touching the thermostat.

Thanks guys for the help, I have a mate who are travelling with us and he had previous trouble with his element, and after checking that another guy came over with his multimeter gear and confirmed that it was the thermostat causing the problem but said he had no idea how to replace it, however he did suggest joining the forum as he said if there is a problem some one has already dealt with it.
At the present moment the fridge is working fine on gas so I will replace the thermostat when I get home in two weeks.
I will post a thread after replacing the thermostat and let any else know what difficulties I run into if any.
Best Regards

So the problem is only when running 240v?
Note:there is no thermostat function on 12VDC operation, the refrigerator works continuously.
