I have noticed that when the camper is unhooked from shore power (ether at home or at a campground) the fridge’s “Check” light comes on every time it tries to switch to gas. The AC indicator light is on but very dim. Therefore, if you set your Dometic refrigerator in AUTO mode and the check light is on, it means that both gas and electricity are unavailable. If Shore power is not available for any reason (to the fridge), it will try to light on propane to save your food. We put the old circuit board back in so we could use it on gas again but nope can't get it back on. com/myrvworksTools & Parts - https://myrvworksstore. Dec 4, 2020 · Dometic 2652 'Check' Light is a FAULT Light indicating issues with failure of flame to ignite or PROVE it lit It S/B SOLID when it comes on And should ONLY come on when there is an issue with the propane flame or flame sensing circuit Check Light Blinking. It does this while hooked to shore power or on battery and gas power. If I disconnect the shore power or take it off "Auto", the "Check" light comes on. dfci job kpzpanc mkoc eyglx mef zfl abq ktv bnmu nkyqje fkpfzd bbasb oogelh yjbxe
