No power to fridge HELP

[Wetcoastoil]

Hi everyone, hoping someone out there can help me with my problem.

Day before our 4 day trip and lost power to the fridge, no lites or power.

Reset breakers, changed fuses.

Anyone have any ideas out there?

Do you mean 'No power to receptacles and lights in the trailer?' Or just to the refrigerator? If you have a digital multimeter, checking the terminal block behind the outside access panel to the refrigerator will help narrow down the problems to find the solution. Check the receptacle outside next to the entry door. Try to reset it. If it will not reset, go outside, disconnect the power cable at the trailer and use the meter to check to see if you have 120 volts to the trailer. That's a start, and I expect more help will soon arrive with suggestions.

I assume you still have both AC and DC power elsewhere in the trailer. What fuse(s) did you replace? In addition to the fuses in the power center, there is also a small DC fuse on the control board in the exterior section - you have to remove the cover over the control board to access it. Check that one if you haven't already.

Also check all the connection on the top panel. We lost power to the fridge once. Checked all fuses n then noticed one connection wasn’t seated properly. I pulled and reconnected all the connection and had power back. No issues since

Replaced the 20 amp fuse in the fuse box (labeled fridge) , also replaced the 30 amp fuse in the exterior refrigerator compartment.
All other late guys and plugs are working.

No lights on the refrigerator.

Where is the control board on the exterior section?

The control board that David mentioned is behind the black plastic cover that resides in the lower left of the outside access. Our E19 has the RM2554 refrigerator that came w/o an interior light. Yours?

The following is based on the dometic control board for 3way refrigerators with an integrated igniter. Refer to your manual for a diagram.

All controls operate on 12v. So if there are no lights it is a 12v problem.

Open the outside door to the refrigerator to access the back of the unit. The lower control board is under the plastic cover that has to come off. It has a screw and needs to be pried off with a screwdriver. Refer to your manual.

The board will have 2 fuses, 3 amp and 5 amp. Check those. If they are ok set your multimeter to dc volts and put red probe on the wire going to J4 (dc +) and the black wire on J10 (ground). If you don’t have 12v then dc power isn’t getting to the refrigerator.

If you get 12v at J4 then move to the six wire harness clip in the upper left corner of the board. Unclip the harness but note where the orange and red wires connect to the board. There should be 12v between those connections. If there is 12v then power is going to the upper control board and the problem is either the harness or the upper board.

Even if the upper control board is dark, refer to your manual to see if your model has a “limp mode” that will operate as long as there is power to the refrigerator.

Thanks to everyone for your help.

Viajante, I checked the 3 and 5 amp fuses, all is ok. Don’t have a multimeter, and it’s getting late(still have to pack). Will have to continue this when we return.

Will have to go old school and use coolers.

Thanks again and have a great week!
