Dometic DM2652 - No Power - Stumped - Everything Seems Fine

[needrvhelp]

Got a new horse trailer with LQ - has this fridge in it. Picked it up and it worked fine when I was at dealer. Drove 3 hours now no lights at all will come on, won't cool in AC or propane.

Checked 12V and there is 12V and 120V working fine. Checked continuity of all fuses on circuit board and main board of trailer. All fine.

I am completely stumped what could be wrong... Seems all the power and fuses are working fine.

Thanks for any help.

Verify connector going to the eye-brow is plugged in.

Use this manual to check for DC voltage at lower board and going to upper board.

Incoming DC is there and I think it was J4 or J6 across there is 12V as well.

Did you check on the incoming terminals for 12 volts DC?
Fuse in 12 volt DC distribution panel could be bad. Normally located next to 120 volt AC circuit breakers behind metal plate held in place with thumb screw.

I pulled upper panel and everything is secure. Is there a way to check if that's getting power? On lower circuit board all fuses have continuity (3A & 5A). Can't find any loose plugs at all.


Could the circuit board have gone bad even though it's brand new?

No light on upper panel and you verified you have 12V DC to control module and that fuses on board are good????

Then cable from lower board to upper panel is not fully plugged in or is broken

Pull upper panel and check
