Dometic RM4213s not getting cold

[Groucho]

Hi all, have an issue and wondered if anyone can help.

I have a Dometic RM4213s Fridge and it is firing up on gas and has electrical power but isnt getting cold, any ideas why?

THanks

If you are getting heat from the exhaust then its likely that you have either a blockage in the coolant, or you have lost coolant, or the thermostat is not working.

Coolant blockage is usually fixed by removing the fridge and turning upside down for a few days, giving it a shake now and then, reinstall and fire up.

Coolant loss will be indicated by yellow powdery deposits around the piping, its terminal and needs to be regassed and/or a new plumbing system installed - often cheaper to buy a new fridge!!

Thermostat not working is harder to check without appropriate test tools - initially look for "dry" connectors which stop the 12V circuit working properly - just take each connector off in turn and re-seat it. Sometimes works, not when connected to mains power though.
