Dometic Refrigerator

[Wmass camper]

Model RM1350slmx
In 2019 MHC.
No light in fridge, bulb tests ok.
Stopped cooling on AC. Put on propane works fine. Put back on A/C and now seems to be working. Can't figure why no light. New power supply circuit board installed 2023

Maybe the switch is stuck open when you open the door.

I would use my multimeter and TS the two door switches in the light circuit and verify 12 vdc from control board at J2 to ground

Use schematic ..it’s a simple circuit
