Sorry if this has been covered before but I can't find a link to this particular problem. We have a Dometic RMD 8505 Fridge /Freezer that is around 6 years old It worked very well from new on engine, EHU and Gas until last week – we were away in the MH about three weeks earlier and it was okay then. Last week it wouldn't get cool on any of the three power sources on the journey to the site (80 miles) or when we were on site parked on level ground. The gas pilot light was working but I couldn't hear any clicking when on EHU – I'm not sure if it should click on EHU. I tried it a few times the same day and the following day but still it wouldn't cool. On the next day I tried again and to my delight it cooled down to its correct temperatures and has worked okay since then. The Motorhome hadn't moved since we arrived on the first site but the Dometic continued working when we moved to another site and still seems okay. Any ideas of the possible causes - mains voltage unit and cooling unit have been mentioned as possible reasons when talking to local fridge/freezer engineers – but I wondered if anyone else had had the same problem with the Dometic RMD 8505 ? Any help appreciated.
