Dometic Refrigerator Power Board 3851331011 (RM1350/RM3762/RM3962)
Dometic Refrigerator Power Board 3851331011 (RM1350/RM3762/RM3962) — Product description
The Dometic power control board, part 3851331011, is the OEM circuit board that runs your absorption refrigerator's AC and LP gas operation. If your RM1350, RM3762, RM3962, or DMR702 fridge won't power on, won't switch modes, or has gone dark, this is the direct-fit module that usually brings it back to life.
The Dometic power control board, part number 3851331011, is the brain behind your absorption refrigerator. It's the circuit board that decides when the fridge runs on shore power, when it switches over to LP gas, how hard it drives the heating element, and how it holds your set temperature. When this board fails, the whole fridge goes quiet. And that's usually the moment folks start pricing out a full refrigerator they don't actually need.
This is a direct OEM replacement for the power module in the Dometic RM1350, RM3762, and RM3962, and it fits the DMR702 too. If your unit is one of those models, this is the exact board that shipped from the factory. There are no adapter harnesses to build, no wiring to splice, and no guessing about connector layouts. It seats in the same spot the old one comes out of, with the same plugs.
You'll sometimes see this part called the power module, the main board, or the power supply board. They're all the same thing, the printed circuit board that manages power for the fridge. Dometic built the RM1350, RM3762, and RM3962 as two-way units that run on 120V AC and LP gas, and the 3851331011 board handles that switching logic along with the temperature control. It's the common board across that model group, which is why one part number covers all of them.
How do you know it's the board and not something else? Worth a few minutes before you order. The classic signs of a dead power board are a blank control panel, a fridge that won't come on in either mode, one that runs fine on gas but ignores AC (or the other way around), or a unit that throws error codes and won't clear them. Before you pull the trigger, though, check the easy stuff first. Confirm you've got 120V at the outlet, that the DC fuse is good, and that the shore or house power is actually live.
If the basics check out and the fridge still won't behave, the power board is the likely culprit. Replacing it is a manageable job for anyone comfortable working behind the fridge. You'll get to it through the lower exterior vent or from inside the cabinet, depending on your rig. Kill the 120V shore power and shut off the LP gas at the bottle before you touch anything. Snap a photo of every connector first so you know exactly where each plug goes back. The board is held in with a few screws and the harness plugs are keyed.
Going with the genuine Dometic board matters here. The power module talks to the rest of the fridge, the thermistor, the gas valve, the heating element, and the user panel, and an off-brand board can read those signals differently or drive them wrong. That shows up as poor cooling, nuisance fault codes, or a board that cooks itself in a season. This is the OEM part, so it behaves the way the factory logic expects, and it keeps your refrigerator's fit and function intact.
One tip before install: match the number. Dometic used several board revisions across the years these refrigerators were built, so pull your old board and confirm the printed part number reads 3851331011 before you order. If your fridge is one of the listed models but the old board carries a different number, check your refrigerator's data plate and manual, or reach out and we'll verify the right fit for your serial range.
So who's this for? Owners of Dometic RM1350, RM3762, RM3962, and DMR702 absorption refrigerators, whether that fridge lives in a coach, a fifth wheel, or a boat galley. If your appliance tech has already traced the problem to the power board, or you've done the legwork yourself, this is the part that gets your fridge cold again without the cost and downtime of a full swap. Not sure it's the board? Give us a shout before you order and we'll help you sort it out.

Frequently asked questions
What does the Dometic 3851331011 power control board do?
It's the circuit board that runs your absorption refrigerator. It manages power distribution, switches the fridge between 120V AC and LP gas, drives the heating element, and controls the set temperature. When it fails, the fridge usually won't power on or won't hold temp.
Which Dometic refrigerators does part 3851331011 fit?
It's a direct replacement for the Dometic RM1350, RM3762, and RM3962, and it also fits the DMR702. It's the common power board across that model group, so one part number covers all of them.
Is this a genuine OEM Dometic part?
Yes. This is the OEM Dometic power module, the same board that shipped in these refrigerators from the factory. It drops into the original location with the original connectors, so there are no adapters to build.
How do I know if my refrigerator's power board has failed?
Common signs are a dead control panel, a fridge that won't start in either mode, one that runs on gas but not AC (or the reverse), or persistent error codes. Before ordering, confirm you've got live 120V power and a good DC fuse, since those cause the same symptoms.
Is the power module the same as the circuit board?
Yep. Power module, main board, power supply board, and circuit board all refer to this same printed circuit board that controls the refrigerator.
Does this board control both AC and LP gas operation?
It does. These are two-way refrigerators that run on 120V AC and propane, and this board handles the switching logic and temperature control for both modes.
Can I replace this board myself?
If you're comfortable working behind the fridge, yes. You reach it through the lower exterior vent or the cabinet. Kill the 120V shore power and shut off the LP at the bottle first, and photograph the connectors so each keyed plug goes back where it belongs.
Should I confirm anything before I order?
Pull your old board and check that the printed number reads 3851331011. Dometic used a few board revisions over the years, so matching the number on your existing board is the surest way to get the right fit.
