Dometic RV Fridge Control Boards: Exact Number Cross-Reference

Two Dometic refrigerators with the same model number can have different lower control boards depending on product ID, factory revision or an earlier service-kit conversion. Start with the number printed on your existing board and the refrigerator's full data label. This NewRVParts guide compares the main Dinosaur replacement families and the genuine Dometic 3316348.900 board, without treating a model name as a universal fitment guarantee.

1. Refrigerator data labelRecord the complete RM, DM, DMA or NDR model and its Dometic product number, usually beginning with 921, 958, 960 or 970.
2. Lower-board labelRead the complete 293-, 3850415-, 3850712- or 3316348-series board number from the installed rear controller, including suffix.
3. Upper controls and power modesConfirm eyebrow type (fixed or adjustable temperature), two-way versus three-way operation, and whether a service kit changed the original wiring or gas valve.

Why Dometic control-board fitment varies by product number

Older Dometic absorption refrigerators used 293-prefix black-box controllers. Later service kits and factory designs use different circuitry, connectors and ignition systems. The 3850415.01 and 3850712.01 Dinosaur boards are not general interchangeable replacements, even though both may be listed beside older RM model names in some broad catalog charts.

Fitment rule: The matching refrigerator model establishes which board families to investigate. The actual installed control board and appliance product number establish the starting point for the correct replacement. Inspect a prior conversion carefully; a new board alone may not contain the wiring, gas-valve or eyebrow components required for a retrofit.

Dometic board-number to replacement cross-reference

Original board or control type NewRVParts replacement family Required confirmation
Dometic 2931842.xx, 2931843.xx, 2932177.01, 2932694.017, 2932695.01, 2932770.01, 2932881.01/.010 Dinosaur MICRO P-711 Eligible 293-prefix black-box controllers; match the full number and 2-/3-way setup.
Installed 3850415.01 or an eligible 3850415-xxx kit controller Dinosaur 3850415.01 Requires the appropriate 3850415 service kit already installed and correctly wired; not a general retrofit kit.
3850712-xxx lower controller Dinosaur 3850712.01 Eligible 3850712 family with integral ignition; verify suffix and control configuration.
3316348-series original controller Dinosaur 3850712.01 or Dometic 3316348.900 Match the exact installed number, product ID and OEM supersession instructions before choosing either.
Older RM3501, RM3601, RM3604, RM3801, RM3804, RM4801/RM4804 systems Dinosaur MICRO P-246 Plus — conditional Only when the manufacturer-specified old control/gas-valve arrangement and required jumpers agree.
Front adjustable-temperature eyebrow panel Dinosaur DEADJ — conditional Upper user-control board, not a lower power-control replacement; check its original eyebrow connectors.
Fixed/automatic-temperature thermistor adjustment Dinosaur THERM ADJUSTER — conditional Accessory for supported thermistor systems, not a failed main-board replacement.

Suffixes and original Dometic supersessions can affect the board selected. For example, a 3316348-series part and a 3850712-series part may share an application family, but the exact OEM service instructions and installed hardware still determine whether a particular replacement is acceptable.

Refrigerator models: where to begin the board check

The following common refrigerator groups appear across manufacturer and service-kit cross-reference material. A row is not a blanket claim that one board fits every refrigerator bearing that model designation.

Dometic model family Possible board history What to verify
RM2652 / RM2852 Different board generations occur across product IDs. 293-prefix on selected older systems; 3850415 kit on eligible conversions; later 3850712/3316348 controls must be identified individually. Do not order from the RM model name alone.
RM2454 / RM2554 Older 293-series controller or a later 3850415 service-kit board may be present depending on exact product ID and prior repair. Inspect lower board and upper eyebrow; document any service kit.
NDR1062 / NDR1292 Manufacturer cross-reference tables split by Dometic product-number ranges between MICRO P-711 and 3850415/3850712 families. Match the full product number and installed board.
DM2672 / DM2872 / DMA406x Selected newer control systems are associated with Dometic 3316348-series OEM boards, but configuration and revised parts can vary. Use Dometic product ID and exact controller number, not only DM/DMA family.
Older RM3501 / RM3801 / RM4801 MICRO P-246 Plus may apply with original compatible control and gas valve; some converted gas-valve systems need a different board. Use the manufacturer kit/gas-valve chart before selecting.
12V compressor refrigerators These Dometic absorption-refrigerator black-box boards are not 12V compressor power modules. Use the compressor fridge's own service parts list.

Upper eyebrow boards versus lower power boards

The lower black-box controller operates refrigerator power, heat sources and ignition according to the original system. The front eyebrow board is the user-facing control/display assembly; it is not a substitute for the lower board. A thermistor adjuster is another separate component used only on supported temperature-sensing systems. If the display works but the refrigerator will not cool, the fault may still be in the thermistor, heater, gas valve, burner, wiring or cooling system rather than the board.

Before ordering or installing electrical controls

  1. Photograph the data plate, the installed controller number and all connector positions before removing any wires.
  2. Compare the full original MPN against the replacement manufacturer's current instructions, not a shortened model-family tag.
  3. Verify the correct two-way (AC/LP) or three-way (AC/DC/LP) configuration and the original gas-valve style.
  4. Check the eyebrow controls and thermistor connection. Avoid changing jumpers, fuses or gas-control wiring without the exact manufacturer's instructions.
  5. Have RV refrigerator 120V/12V electrical and LP-gas diagnostics or installation performed by a qualified RV service technician. Disconnect the required power sources before service.

Shop exact Dometic and Dinosaur control parts

These are distinct products. Check the individual listing and the installed board MPN before ordering; a similar black-box enclosure or a refrigerator-model tag is not proof of compatibility.

Repair or replace the whole refrigerator?

When the existing unit has a confirmed control fault, an exact replacement board may be more practical than replacing the full fridge. If the cooling system or cabinet also needs replacement, consult our Dometic-to-Norcold refrigerator size guide, cabinet measuring instructions and 12V refrigerator replacement chart. A new compressor refrigerator uses a different power and ventilation system from these absorption-fridge controllers.

Manufacturer board identification references
