Sorry for the slow reply! Honestly, I can't promise a new board will fix it. If it runs fine on LP and AC when you pick them manually but won't switch on its own in AU, the most common cause is the board not sensing AC properly, and the 628661 usually fixes that. Before you buy, confirm you have a solid 120V at the outlet behind the fridge and a solid 12V at the board, since low voltage on either can cause the same thing.
