Roadtrek Refrigerator - Blinking Control Panel

[NoVa_RT]

The Roadtrek's Dometic refrigerator was working fine on AC, until the middle of last night when I woke up to the control panel blinking. Couldn't get it to work at all on AC, and on DC the control panel lights would start blinking after a minute. The manual doesn't address this, so I shut it off, figuring the few things in there would be OK until morning,

No better luck this morning, although it looks like it may be running OK on propane, which I normally don't use when I have electricity. Anybody had this problem or have thoughts on what might be the cause?

Hoobbssb,

You can find a manual for your fridge online- it suggests "resetting" the warning light by powering off then on.

Mine seems to get confused if we are running on shore power, and there is a power interruption.

power off, wait a moment, power on

Last week our Dometic warning light started blinking while running on propane but OK in other modes. As we like to dry camp and were half way on a trip to Colorado, no propane mode would have been a disaster. But, with thanks to you all who suggested turning off and then turning on the fridge, it started working again. BIG THANKS TO YOU ALL!!!

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.

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.

. . . 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.

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.

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.

What Model?

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.

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.
