The board uses a three-pin top row and seven-pin bottom row configuration; older control boards with different port counts (eight or ten on the bottom) or legacy Micro p-711\/\"293\" series boards are not compatible. The module includes both AC and 12V DC power management and an integrated propane igniter circuit to restore the refrigerator's electrical and gas ignition functions.\n\n\u003ch3\u003eHow do I know if this board fits my refrigerator?\u003c\/h3\u003e\n\u003cp\u003eCompatibility hinges on the connector arrangement and model family. Inspect your existing lower control board: the Bxmgr 3316348.900 has three pins across the top and seven pins across the bottom. If your board shows eight or ten bottom pins, or if it is an older \"dinosaur\" board or a Micro p-711 series beginning with \"293,\" this unit will not replace it.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCheck the physical pin count: 3 top \/ 7 bottom required.\u003c\/li\u003e\n  \u003cli\u003eCompare part numbers – this replaces 3316348900, 3316348.000 and similar listed numbers.\u003c\/li\u003e\n  \u003cli\u003eWorks with many DM and RM Dometic models but confirm interfaces visually.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat functions does this replacement control board restore?\u003c\/h3\u003e\n\u003cp\u003eThis lower control board handles propane ignition, powers AC components, and routes 12V DC to the refrigerator’s subsystems.

This replacement board is intended for RV owners, repair technicians, and parts suppliers working on Dometic\/RM absorption refrigerators who need a drop-in lower control board with a 3-top\/7-bottom pin layout. If you can confirm the connector pattern and compatible model numbers, the Bxmgr 3316348.900 restores ignition and AC\/12V power functions and comes with manufacturer-backed coverage. If your fridge uses an older eight- or ten-port lower board or a Micro p-711 series, seek the specific legacy part instead.\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this board fit all DM2652\/RM2652 refrigerators?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits many DM2652\/RM2652 variants only if your old board has 3 top pins and 7 bottom pins; eight- or ten-port boards are incompatible.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What warranty and support come with the Bxmgr 3316348.900?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: This product includes manufacturer warranty coverage and customer support; contact Bxmgr for exact warranty terms and installation help.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Bxmgr","offers":[{"title":"Default Title","offer_id":48086385098910,"sku":"B0BZSN8LFN","price":49.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/bxmgr-front-view-board-with-connectors.jpg?v=1785897040","url":"https:\/\/northtrailauto.ca\/products\/bxmgr-rv-fridge-control-board-replacement-3-top-7-bottom-pin-propane-igniter-with-ac-12v-power-control","provider":"North Trail Auto","version":"1.0","type":"link"}
