Refrigerator didn't switch to gas?

My Jacyo 26 RKS is permanently attached to shore power with no back-up battery. However, the breaker was tripped (a bird decided to build a nest in the breaker box) and the trailer had no power for a week or more. When we discovered it, we thought the refrigerator would switch automatically over to GAS, but it did not. The unit was on AUTO, the propane take was full and the gas line valve was open. I'm now back on shore power, but I want to make sure it doesn't happen again (lost a full box of food).

Is there maintenance I should have done? Could the switch be bad?

It needs 12 volt to operate the control circuit, without shore power and no battery it's not going to work.

The refrigerator will automatically switch to gas when you lose shore power PROVIDED these two conditions are met. 1, Gas supply must be turned on. 2, and most likely the reason yours didn't YOU NEED TO HAVE THE BATTERY connected. Without either 120 Volt or 12 volt supply the ignition (spark) circuit will not function

The Norcold refrigerator requires 12VDC to operate even when the running on gas. This means the 12VDC circuit must be connected in the RV, and the converter connected to shore power which supplies the 12VDC.

The next question many people ask is why doesn't the ice maker work when operating on 12VDC with gas.
The Norcold ice maker requires 120VAC to operate. This means the fridge must be on shore power, and have a continuous supply of water.

We had a 26RKS until last month when we traded up to a 338RES. Agree that you must have a power source for the electronics to work. Check your battery to make sure there was backup power available. One other thing to watch very carefully is the propane supply hose. It runs along the slide mechanism and "folds" as you retract the slide. There are springs around the hose at the pinch points to keep the hose from kinking but they tend to move resulting in a pinched hose. When this happens, propane can't flow to your fridge. The position of those springs became something we checked every time before closing the slide.
