Dometic 4 door fridge

[Glenn54]

We've been living in our 2014 Avalanche 5th wheel for about 7 months. Fridge worked great until a few days ago. Now the fridge has completely quit working. No lights on the panel. Pushed the on/off and auto buttons, nothing. Switched to the full propane tank. Checked the 3 fuses behind fridge, they're good. Made sure the battery is good, 13.8 volts. Any other ideas?

Go outside and remove the lower access panel. You should see a plastic connector on the lower left side with the 12V feed on one side and the 12V wires from the fridge on the other. Verify voltage there, and if there is then,


Look at the square plastic cover above it with a bunch of wires going onto it. That cover covers the control board, and it may have a fuse on it.

Thanks Chuckster. I will give these a look after work today.

Round 2 of testing. Fuses test ok. Checked 12v line coming in where a 4amp fuse is located. I have 12 volts there and leading into a "Rayex Elec" coil. None of the other wires coming out of coil have any voltage. I'm not an electrician but does it sound like this coil is the problem? Also checked the 120v plug and it's good. 2 pics below are where I found the fuses, 1 in main line and 2 in black box. 3rd pic is the coil I'm suspecting. How do I prevent pics from flipping upside down?

I don't think that's a coil, but rather a relay.

Try giving it a good tap on the top.

It should have a P/N on the top, and it might be possible to get a relay from an auto parts store.
