    Dometic RM1350SLM refer stopped working

    Unit stopped working during 4th trip. Replaced blown 4a and 5a glass fuses. Heater works, fans ok, mini-fuse is good, 120v outlet is good, 12v input good, no error codes. Turns on and can hear fans operate. Temp display remains at 60. What’s left to check? Five months old and under warranty. Just trying to check all I can before giving it up for an extended stay at the dealer. Thanks for any suggestions.

    Hi. You said your 4a @ 5a fuses were blown. Do you know what are on those circuits? That may help you figure out what’s wrong. If you don’t know what’s on those circuits go on line or see if you have service manuals to help solve issues. On page 23 of the Dometic rm1350 diagnosis manual it tells you what all three fuses protect. Understanding this may help you solve or at least give you an idea what may be wrong. Hope this is some help in finding your issue.

    Additional info: thermistor shows 8500 ohms, heater has continuity and gets hot.
    I have read on the forum that if the heater works, the circuit board is good. So,
    what’s next ? Thanks
