Dometic RN4271 fridge runs in 240v, and gas.
The fridge 12v supply from the car is operated via ignition relay, and the +ve line to the pin socket shows normal voltage. Of note is the relay inside the car engine bay and the regular relay in the distribution area in the van on the 12v+ve feed. I don't think this is an issue.
The return line (-ve) from the fridge shows .07 volts and I have connected that to the the earth side of the car battery.
Running the car, I get normal indicator light showing when I turn on the 12v switch, but no cooling.
Yes, have checked the 12v fuse at the onboard distribution.
Van has not been used for some 5 months, and the tug is a different one from previous excursions. Had to change the plug setup to a 12 pin flat to match the towcar.
Perhaps the 12v heating element has failed?
Suggestions welcome.
