If your Dometic RV fridge is acting up—not cooling, not switching modes correctly, or just being finicky—the problem might be the main control board.

This is a brand new, genuine Dometic part, model number 2890189307.
It's the main PCB that mounts at the rear of the fridge, specifically for the RMD8555 and RMDX series of upright 3-way fridges (the ones that run on gas, 12V, and 120V).
This little board is the brain of the operation.
If it goes bad, the fridge won't work right.

This one is new, not refurbished.

The dimensions are roughly 30cm long, 25cm wide, and 10cm high, but obviously, you're buying it for the electronics, not the size.

It has a UPC of 734189615709.

Before you go buying a whole new fridge or paying a tech a ton to diagnose it, swapping out this main PCB might just solve your problem.

It's a direct replacement for the factory board.

Get your camper's fridge back to keeping things cold with this Dometic part.
