RV appliance control board finder
A fridge that stops cooling, a generator that will not start, a furnace that will not light: the board is the usual cause, and it is the part that decides whether the appliance is worth repairing. Dinosaur Electronics publishes the only public charts mapping a maker's model or part number to the board that replaces it, across four charts. Type what you have and this reads all of them.
Every board number below is a maker's, taken from a chart cited beside it. Four charts, one search. Nothing is sent anywhere.
What appliance, or what board, do you have?
How to get it: a refrigerator model reads like RM 2652, NDR 1062 or 6182, on the rating plate inside the door. A board or appliance part number looks like 2931842.01, 3850712.01 or 300-0859, and it is printed on the part itself. Any of them works here.
Why the board is the part that decides it
A gas-absorption refrigerator has no compressor. It cools by heating a sealed circuit, and the electronics decide when to heat, how much, and whether the gas burner is lit at all. The control board is that electronics, and it is what fails when a fridge goes warm on both gas and electric power, when it works on one and not the other, or when it will not light at all.
The same kind of board runs the other gas appliances. A furnace and a water heater light through an ignitor board, and a generator's control board decides whether it starts and whether it keeps running. All three are the same class of part, and the same four charts answer all three.
Dinosaur Electronics builds replacement boards for both big makers, and its charts are the reference the trade uses for the substitution, because the original manufacturers do not publish their own replacement charts. That is the whole reason this tool exists: the OEM numbers are on the charts, and the charts are the only public source that pairs them with a board you can still buy.
One model, more than one board
An older Dometic refrigerator was often built with two or three different boards over its production life, and the model number alone does not say which one yours has. The charts handle this with a production number range, and so does this tool: where a model has more than one board, every range is listed rather than a single number being picked for you.
That production number is on the refrigerator's own rating plate, next to the model. On a Norcold the plate is on a tag inside the fresh-food compartment; on a Dometic it is inside the door on most models. Reading it before ordering is worth the two minutes.
The eyebrow board, and why it comes up
On a Norcold the charts name two parts: the control board and an eyebrow board, which is the display panel. They are separate parts, and the charts pair them by model. A failed control board is often what takes the eyebrow with it, which is why the two are usually bought together rather than one at a time.
What this does not cover
It does not cover every board ever built, only the ones Dinosaur makes a replacement for and names in these charts. A board the charts do not mention will come back as not found, and that is a statement about the charts rather than about your appliance.
And it does not tell you whether the board is the fault. A fridge that works on gas but not on electric, or the other way round, has a fault on one side of the board rather than in it, and the board is a costly thing to replace by guesswork. The refrigerator not cooling guide walks you through the diagnosis in order before you buy anything.
Where to go next
The RV refrigerator not cooling guide separates a board fault from a cooling fault. An air conditioner not cooling is the same split on the roof unit, and the converter finder covers the 12-volt supply these boards run on. The parts page lists the control boards and igniters by appliance. Fitting a board is a job a mobile technician can do, and the directory finds one by state.
