Roadtrek Refrigerator - Blinking Control Panel

Are you parked level?

Are you parked level?

I'm within the center bubble both front-to-back and side-to-side, so I don't think leveling is the problem. Not really sure I'm getting much cooling on propane, either, although it was probably more like afternoon by the time I gave that a try & just turned it up to a higher setting half an hour ago since I wasn't sure I was getting more than the residual cooling from yesterday. The control panel is working normally on propane, unlike the blinking on DC & not lighting up on AC.

When in TX a few years ago, we returned from a day outing to find our frig "blinking". Apparently, while getting our cooler packed for the day, I inadvertently bumped the sensor and it slipped out of place. Don't know if this will help. Just what our manual suggested we check. Re-adjusted and worked fine from then on.

What Model?

Now everything is out. No lights at all on control panel. Hitting ON switch gets the briefest flicker of light at end of temperature setting light, but it quickly goes out and the refrig doesn't respond in any mode.

The manual covers several models, and my controls match the diagram for the RM2354, RM2454, RM2554 & DM2663. I think I'm the RM2354, which I believe is the smallest. In any event, with everything out, it's not looking like there will be a quick fix.

We had a problem with our Dometic. Looked like it was an issue with the control board. Digital display made no sense. Took it to CW. They were very busy and I waited over two hours. They suggested early on that they thought I must need a new board based on symptoms. $500. I waited some more and the assistant went back to check and confirmed that a new board was needed. It didn't feel right but I authorized the order, put a deposit on it and went home. We were doing some other odds and ends and turned off the main battery switch. When we turned it back on the refrigerator operated normally in all modes. Lesson learned - I don't think there's any way that CW could have disconnected the control board as instructed in some troubleshooting that I'd seen. So, if you haven't turned off all battery power, try that.

. . . if you haven't turned off all battery power, try that.

I had flipped the circuit breakers earlier, to no effect, but with nothing to lose I tried Pickerel Cove's suggestion and flipped the Battery Disconnect switch off and then back. Surprise - the Control Panel lights came on and responded to my switching to AC, although I'm not sure I got any cooling, since I didn't hear anything running, even though I usually don't notice refrig sounds. But within two minutes all the Control Panel lights were out again & didn't respond further.

Tried turning the refrigerator back on this afternoon, after 2 days of "resting", and somewhat surprisingly, it seems to work. Control Panel lit up and I put it on A/C with no problem. It's been cooling for about 6 hours, so I'm keeping my fingers crossed. Perhaps I have a finicky sensor of some kind, but it is encouraging that the cooling mechanism works, at least for now.

Sounds to me like a circuit board reset. Heh. My expensive washing machine did the same. Power down and wait a few minutes and then power up. Turning off the house power switch and then on again would do the same. Usually, if a board has a fault it will stop running ie the convertor in my earlier C class. It died quietly and did not reset even with 30 amp switches reset. Cheers.
