Bxmgr RV Fridge Control Board replacement — 3-top/7-bottom pin, propane igniter with AC & 12V power control

Bxmgr 3316348.900 is a replacement lower control board for gas-absorption RV refrigerators that manages propane ignition and AC power functions. This control board is designed as a direct-fit replacement for many Dometic and RM series absorption refrigerators, but it is essential to confirm connector layout before ordering. 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.

How do I know if this board fits my refrigerator?

Compatibility 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.

• Check the physical pin count: 3 top / 7 bottom required.
• Compare part numbers – this replaces 3316348900, 3316348.000 and similar listed numbers.
• Works with many DM and RM Dometic models but confirm interfaces visually.

What functions does this replacement control board restore?

This lower control board handles propane ignition, powers AC components, and routes 12V DC to the refrigerator’s subsystems. It controls thermostat inputs, AC line and neutral outputs, and connections to the gas valve and thermistor, helping bring back lighting, heating, and ignition features when the original board fails.

• Integrated propane igniter for gas operation control.
• AC line and neutral routing for heater and lighting.
• 12V DC supply management for sensors and internal circuits.

Which Dometic/RM models and part numbers are supported?

The Bxmgr 3316348.900 is compatible with a wide list of Dometic and RM refrigerators, provided the connector layout matches. It replaces several previous part numbers and suits many DM2652/RM2652 variants plus other DM and RM series models, but always verify port count before assuming fitment.

• Common compatible models: DM2652, RM2652, DM2662, DM2672, DM2682, RM2852, RM2862 and more.
• Replaces older part numbers like 3316348900 and 3316348.000 (see full compatibility list).
• Not compatible with Micro p-711 or boards starting with "293" and other legacy eight-port boards.

What are the electrical specifications and key connector functions?

The board is built to operate on typical RV electrical supplies and includes labeled connector points for straightforward wiring. It accepts 120V AC and supplies 12V DC to select circuits; fuse and terminal assignments are noted so an experienced technician can match connections during installation.

• Power ratings: 120V AC at 3.5A, 60Hz and 12V DC at 1.9A.
• Connector functions: thermistor, gas valve, indoor lighting/climate, AC line/neutral, chassis ground, and more.
• Designed as the refrigerator’s lower/main control board for ignition and power distribution.

Who is this for? 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.

FAQ

Q: Does this board fit all DM2652/RM2652 refrigerators?
