In AUTO, the board uses AC whenever it detects enough AC voltage. If it works in AC and LP modes but not AUTO, it may not be detecting the AC properly, often from low AC voltage at the outlet or a board problem. Check the AC voltage at the fridge's outlet under load. If the voltage is good, the board's AC sensing is the likely cause, and the 628661 power board is in stock.
