Dometic 3-Way Fridge Diagnostic (Check Light Faintly On)
I'm helping a friend with a 2005ish Lance camper and his Dometic "Royale" RM3663 3-way refrigerator. It ran fine when he bought it last April, and wasn't used much while we did other projects. We started it again three weeks ago and it worked properly. In that time, it went to a mechanic for the truck, and was left on for two weeks. The battery drained, and the fridge came back with the "check" light on. My friend turned it off, and then restarted it a couple days ago. At that time, the "Check" light was on, but much fainter than the other lights. It never got cold, even after two full days. The temp selector is set to coldest. It's maybe getting a little cooler than ambient, but certainly not cold. There's power to the panel, and power to the inside lights. We have turned off propane, purged the line, and restarted the whole system. The problem persists. We tried it on DC and there's no change to the light. No change with AC, either. The only other thing I can think of that may be a symptom is that the auto/gas button doesn't feel like it presses the same as the others. It still seems to cycle, but it doesn't depress cleanly like the others. I don't have pictures on my computer, but I'll update this with pictures from my phone in a few minutes. Any suggestions about troubleshooting, or are we looking at component (panel or coil) replacement or fridge replacement?3.5KViews0likes6Comments
