This Bxmgr 3316348.900 control board is a drop-in lower power module designed for a wide range of Dometic DM and RM series refrigerators. It handles the propane ignition circuit and supplies AC and DC power to the fridge components. Before ordering, check the pin layout on your existing board: this version has three pins on the top and seven pins on the bottom. Older boards with eight or ten bottom pins or legacy microboards (part numbers beginning with "293" or long-legacy designs) may not be compatible.

• Top row: 3 pins; bottom row: 7 pins — confirm visually against your board.
• Supported Dometic models include DM2652, RM2652, DM2662, DM2672 and many RM/NDM/NDR variants.
