2018 Lexor TS Refrigerator Troubleshooting
Our Dometic RML 8330 UL fridge wasn’t working on 12 Volt DC. This had happened a couple of years ago and it was a non-working circuit breaker. This time we traced it to the DC 12V 30A relay.
We followed the power to the relay with a multimeter.
Access the area from the outside lower vent.
The 30 amp circuit wasn’t closing, but there was 12 volts to the control leads when we switched the control dial to DC.
The relay is screwed to the back of the fridge.
It was easy to change as all the wires have slip-on spade terminals.
Found a replacement online at Panther RV Products and it arrived from across the country in 3 days. The part info is:
MC Enterprise 2930385006MC Aftermarket Dometic RV Refrigerator Power Relay, just in case anyone else runs into this problem. https://pantherrvproducts.com
The replacement relay isn’t specific to Dometic Refrigerators, so search for this 12 volt / 30 amp relay if you experience a failure on your fridge.
