Overview

Genuine Dometic 4441000010 electronic control unit for the Danfoss / Secop BD35F and BD50F compressors. The control unit is the “brain” that drives the compressor — when it fails, the fridge stops cooling even though the compressor itself is fine.

Suits the following fridges and compressors:

Dometic CFX series (CFX-28, CFX-35, CFX-40, CFX-50, CFX-65, CFX-65DZ, CFX-95DZW, CFX5 series and others using BD35F/BD50F)
Dometic CDF series, CF series
Dometic CRX, CR built-in caravan fridges using BD35/BD50 compressors
Waeco-branded predecessors and many third-party fridges (Engel, Evakool, National Luna, Vitrifrigo, Isotherm and similar) using the same Danfoss compressor platform

Specifications

Operating voltage: 12V / 24V DC
Compatible compressors: Danfoss BD35F, BD50F (post-1998 models)
Dimensions: approx. 110 × 90 × 50 mm
Weight: approx. 320 g
Genuine Dometic part — 3-month manufacturer warranty

Why this part fails: heat fatigue, voltage spikes, water ingress and normal aging. If the compressor cycles incorrectly, error LEDs flash, or the unit refuses to start — replacing the control module is the standard first repair before condemning the compressor.

Common questions

How do I know it is the control unit and not the compressor?

The usual sign is a fridge that powers up and does nothing — no cooling, no compressor noise. A failing compressor tends to try to start and cut out. Before you condemn either, check the supply voltage at the fridge, because low voltage produces the same symptom.

Will it fit where the old one came out?

It keeps the same 110 x 90 x 50 mm form factor as the superseded units, so it drops into the existing bracket without cutting or drilling. Photograph the wiring before you unplug anything — the connections are straightforward, but memory is not.

Is this a job I can do myself?

Generally yes, because swapping the control unit does not open the sealed refrigerant circuit. It is a 320 g electrical part that unplugs and re-plugs into the same mount. Anything touching the gas side needs a licensed refrigeration technician, but this job does not, so it is a reasonable home repair.
