Refrigerator Intermittent on Shore Power

[Justicebrian]

I have a 2020 Montana High Country with a Dometic RM1350SLMX refrigerator. When I am connected to shore power, it will switch over to gas.

Here is what I have checked:
- I have 120V to outlet
- fuses are good
- I have 120V to the fuses
- the heater element OHMs out correctly
- I have 120V going to the heating element terminals

From this, it seems like it is working correctly, but I will hear it switch over to gas while we are camping. I do not know if this is intermittent or why it switches over to gas. This has happened at several places we have camped, so I do not think it is the incoming power quality.

Could this be a board problem? Anything else I should check? Any help is appreciated!

I don't have the same trailer, but if all of the electrical contacts are good and are tight, I would bet that you are right. The control is suspect. Mine has an AUTO and a GAS setting and I think a check light that flashes in case there is an interruption (probably a failure to ignite gas). Auto is electrical preferance if the electrical and gas are both available.

It could be the control board or possibly the eyebrow board.
