Dometic Fridge Panel Lights not working
I have a Dometic DM2862RBX fridge. It's working on electricity, both shore power and (drained my) battery bank. The power switch works, but none of the panel lights are working and I can't seem to switch it to LP.
Has anyone else encountered or fixed this problem before?
Any chance I can switch to LP manually?
Any help would be very appreciated, thanks!

What is your DC System Voltage?
Got to have 12V DC for fridge to function
Measure the DC Voltage AT terminal block in fridge outside compartment
GOT 12V DC at terminal block then check for DC Voltage to/thru 'Thermo-Fuse'.....follow RED wire from terminal block to thermo-fuse on stack
DC goes from thermo-fuse to lower circuit board at J4 terminal
Also check that the 3A fuse (far left on circuit board tests GOOD)
IF after those checks and you have DC Voltage then you will need to test the 6 pin connector (top left on circuit board)...that harness supplies DC to Display panel and commands form display to circuit board
Can not Swap to LP without display panel

The on-off switch on the panel still works as does the inside door light. The fridge is functioning on AC electricity with shore or inverter. None of the panel lights or other functions seem to work.
I'll report back after I've checked fuses and those DC voltages. It's cold and dark, I'll wait till daylight.

Interior light works, ON/OFF works.......then you have DC
Panel display harness or plug connectors not making good contact OR display board (eyebrow) faulty

Thanks for the help.
My fridge panel lights did briefly come on for a minute or so after I turned it back on, I set it to gas and a few minutes later the panel light shut off again and switched back to AC. Ugh.
So there's some intermittent contact issue involved so it looks like I'm going to have to try everything.

So, there is 12v at the block, 12v to the board on J2, 12v to J4. I checked and the harness seems to be fine. Fuses are fine. So it appears it's either a bad main circuit board or eyebrow?
The eyebrow will sometimes turn on for a few seconds or a few minutes, all of the functions will appear to work and then will abruptly shut off. The gas pilot does flame up if the fridge is disconnect from 110v. If it's connected, it draws 30+ amps from my inverter.
So is there any advantage to buying the Dinosaur Electronics replacement main board? Or do you think it's the eyebrow board?

edit to the 2nd paragraph for clarity:
The eyebrow will sometimes turn on for a few seconds or a few minutes, all of the led functions will appear to work and then will abruptly shut off. The gas pilot does flame up if the fridge is disconnect from 110v when the leds are not functioning. If it's connected and the leds are not working, it draws 30+ amps from my inverter.
