Aoryimt Dometic RV Refrigerator Replacement Control Board 3316348.900 (7‑pin) — 120V/12V Ignition & Propane Control

Aoryimt's 3316348.900 / 3316348.000 replacement control board restores ignition, AC power and propane control for compatible Dometic RV refrigerators. This replacement lower control board is a direct-fit electronics module designed to take over ignition and power management duties in many Dometic absorption-style fridges. It handles both mains and 12V inputs, drives the propane igniter, and interfaces with the upper board, thermistor and gas valve so your refrigerator can cool reliably. The unit from Aoryimt includes an upgraded seven-interface connector layout — check your original board before ordering to ensure compatibility.

How do I know if this control board fits my Dometic fridge?

Confirm fitment by comparing part numbers and connector counts on your existing lower board. This Aoryimt module replaces OEM numbers such as 3316348900 and several related service references, and it is intended for many DM and RM series models.

• Matches Dometic family models (DM2652, RM2652, DM2662, DM2672, DM2682, and others listed).
• Replaces part numbers like 3316348.900, 3316348.000 and several aftermarket codes.
• Upgraded with seven connection interfaces; not compatible with older ten-pin or eight-port/dinosaur-style boards.

What electrical functions and connections does this board handle?

The board manages primary power inputs and the propane ignition circuit while providing outputs for heater and lighting functions. It accepts both 120V AC and 12V DC supplies and routes signals to the gas valve, thermistor and other subsystems.

• Power inputs: 120V AC (60Hz, 3.5A) and 12V DC (1.9A).
• Integrated propane ignition control and outputs to AC heater and lighting circuits.
• Connector layout includes designated pins for thermistor, gas valve, lighting/climate control and chassis ground.

What should I watch for during installation and compatibility checks?

Before installing, verify the number of interfaces and that your fridge is not a legacy/dinosaur or 293-series board. Use the connector map to match P1–J10 functions and take note of which wires go to the gas valve, thermistor and upper control board.

• Confirm seven-interface layout; incompatible with ten-connection port and eight-port boards.
• Cross-check P1–P3 and J2–J10 pin functions with your existing wiring harness.
• Power off and disconnect batteries and mains before replacing the lower control board.

What support and warranty come with the Aoryimt replacement board?

Aoryimt offers a 12-month after-sales service covering faults and installation questions. Customer service can help troubleshoot compatibility or functional issues after purchase.

• 12 months of warranty-backed support from Aoryimt.
• Assistance with installation questions and troubleshooting guidance.
• Contact Aoryimt if the board behaves unexpectedly after fitment.

This replacement lower control board is intended for RV owners, technicians and service shops needing a dependable electronics module to restore refrigerator operation after a failed control board. It’s best for Dometic absorption refrigerators listed in the compatibility set, where the original lower board has lost ignition, AC power routing, or control functions. If you’re unsure about fitment, gather the original board part number, count the connector pins, and consult product images or Aoryimt support before ordering to prevent incompatibility.
