LP on Fridge not functioning?

[Greyhawk31ss]

Have an older Greyhawk 31, Fridge works fine on shore power or generator. Stove functions fine on LP, but the fridge in auto mode or LP mode doesn’t cool. Any tips on troubleshooting?

I think you still need a solid 12V supply for the 'fridge to work on LP. How's the house battery looking?

With my 31F, house battery voltage was 13+volts. By the time power got to the propane shut off valve, it was 11'ish. The valve needs 12 volts. My fridge wouldn't work.

I ran a dedicated power supply direct to the back of the fridge from the 12 volt electrical panel.

This site has very good trouble shooting. Fridge Defend by ARP Protects your Dometic or Norcold
Mine ended up being the inline filter before the jet, it is very small.

Check for muddobbers nests around the burner outside. Remove the lower outside vent cover to inspect. It happened to me but worked fine after chipping out the mud and using canned air to blow out dust.
