Hi, yes I am in Australia. Thanks for the prompt reply Kirk. The service manual link that you sent has been helpfull with other controls that I didn't know about. As for the unit switching itself back on at random, the problem seems to have corrected itself. It is working perfectly now. Maybe charging the vans batteries did the trick? Cheers, Ken

My Dometic absorption refrigerator RMD8551 recently developed a problem after returning from a trip that it would not turn off. The last power source it ran on was 12 volt fed from the caravan battery & vehicle when travelling. I turned it off the usual way on the control panel & proceeded to clean it inside when it turned itself back onto 12 volt , which was the last energy source it ran on. I turned it off again & 10 seconds later it turned itself back on .I switched it to mains power (240 volt) to see if I could trick it). However it switched back on again even with repeated attempts at turning it off. The button switch on the control panel seems to be working ok as after pressing it the refrigerator shuts off for 10 seconds then restarts. I removed the wiring harness from the PCB & re-seated it , no improvement. The Dometic tech guy suggested changing the PCB , at $380 it would be an expensive guess with no guarantee of it fixing the problem. I have been removing the fuse from the control circuit temporarily to shut it down till I can solve the problem. The refrigerator still works ok on the cooling side with all 3 power sources. Has anyone got any ideas? Cheers Ken.
