Aoryimt RV Refrigerator Control Board Replacement 3316348.900/3316348.000 — 7-interface Propane Ignition & AC/DC Power

The Aoryimt 3316348.900 / 3316348.000 is a drop-in replacement lower control board for many Dometic gas-absorption RV refrigerators, managing propane ignition and AC/DC power functions.

This replacement circuit board restores control of propane ignition, AC power distribution, and DC supplies for compatible Dometic fridge models. Engineered to match the electrical layout of the original lower module, this Aoryimt board includes upgraded connectors and multiple interfaces to fit a wide range of current Dometic power modules. It’s intended for RV owners, technicians, and fleet maintainers who need a reliable swap-in board to get a fridge back to functioning safely and predictably.

How do I know this board fits my Dometic refrigerator?

Check the part number and connector count on your existing lower control board before buying. This Aoryimt replacement is compatible with many modern Dometic modules but uses a seven-interface layout; it will not work with older boards featuring ten ports, 'dinosaur' style boards, the '293' series, or eight-port models.

• Compare your original part numbers to the listed compatible replacements (3316348.900, 3316348.000, etc.).
• Verify your fridge’s connector count—this unit uses seven interfaces.
• Inspect the physical pin layout and mounting to confirm a clean fit.

What functions does this control board perform?

This lower control module handles propane ignition, AC power routing, and DC power distribution for the refrigerator’s components. It supplies 120V AC at up to 3.5A and 12V DC at up to 1.9A and includes an integrated propane igniter circuit to manage gas operation safely when compatible.

• Controls propane ignition and safety circuits for gas operation.
• Routes AC line and neutral outputs to heaters and switches.
• Provides 12V DC power to interior lights and controls.

Which original part numbers does this replace and what are the connections?

The Aoryimt board replaces multiple OEM part numbers and populates the same functional connections required by current Dometic refrigerators. It maps the fuse cover terminals and connectors for upper-board communications, thermistor input, gas valve, lighting/climate outputs, and AC/DC power terminals.

• Replaces 3316348900, 3316348.000, 3316348000 and other listed variants.
• Terminal mapping includes P1 (upper control board), P2 (thermistor), P3 (gas valve), and J4–J10 for power outputs.
• Not compatible with older 10-pin or 8-pin/dinosaur-style boards—confirm before purchase.

What should I expect during installation and aftercare?

Installation requires basic electrical and mechanical competence: power down the refrigerator, disconnect batteries and shore power, remove the lower access panel, and swap the board securing screws and connectors. After installation, test propane ignition, AC heater outputs, and 12V functions; the product includes a 12-month after-sales service for peace of mind.

• Power off AC and DC sources before handling the board.
• Label connectors during removal to ensure correct reattachment.
• Run a full functional check of gas ignition and AC/DC outputs after fitment.

Who is this for? The Aoryimt 3316348.900 / 3316348.000 control board is designed for RV owners, mobile-home technicians, and service shops replacing faulty lower control modules in compatible Dometic absorption refrigerators. It’s suited to anyone comfortable with wiring and component replacement who needs a reliable, a la carte replacement for ignition and power control functions—provided the connector layout matches your unit. If your unit uses older 10-connector, 8-port, or '293' series boards, choose a compatible alternative instead of this model.
