Dometic fridge won't start on GAS mode
We have a 3-way fridge (Dometic RM2454). Yesterday evening, while running in AUTO mode and on GAS, the GAS light switched to "CHECK". This usually means the propane is out so I replaced the propane tank. I tested by running the cooktop for 20 seconds and it worked fine. When I looked at the fridge however, it was still in "CHECK" mode. I could hear the fridge (electrode) "clicking" for about 20-30 seconds but the fridge didn't switch back to GAS mode.
So, I went outside the RV and opened the fridge's back panel door. I opened the burner housing and observed what it was doing. I saw the electrode create a spark with every clicking sound and immediately after the first click or two, the blue flame ignited. The blue flame kept burning until, after 20-30 seconds of the electrode repeatedly clicking, the clicking stopped and the propane supply was shut off so the flame went out.
I tested again by turning off the manual gas shutoff valve in the burner housing. Now the electrode just clicked (creating sparks) for 20-30 seconds without the flame coming on. However, as soon as I switched the manual gas shutoff valve on again, the electrode sparks lit the blue flame. Same end result however: after 20-30 secs of clicking, the electrode stopped clicking and the flame instantly died (I assume the fridge stopped the gas supply to the flame).
Does someone know how to fix this? It acts as if it doesn't detect the flame ...
Thanks!
P.S. Other than in GAS mode, the fridge works fine in DC mode (which I only use while driving since we usually boondock and I don't want to drain the battery).
