Dometic Check Light

I am getting a check light on shore power, generator, and gas. I am thinking the controller board is bad? It was working on gas while boondocking and started throwing check lights after starting the generator. Model DM2652RBX. Anyone have any hints?

Thanks.

Check and try this.
If you have right or left two lights blinking it may be a overheating condition while on propane.

A. Check the flu behind the fridge and ensure nothing is blocking (insulation or critters, bugs).

B. Reset the resetable fuse located on the flu itself (button is in between the 2 wires on the round sensor).

You say it started showing the check light after starting the generator? Have you checked the fuses on the board to make sure they're not blown or even loose?

Try the reset Iggy mentioned and also there's a thermal fuse hidden in the wiring that looks like a metal diode.

Yes it was the control board, replaced it and boondocked again for 6 days, worked flawlessly!
