Miele Electronic Unit for Gemini & Leo S5381

Miele electronic unit 7489980 is the model-specific control board for the Gemini and Leo S5381 canister vacuums sold in North America. Unlike the shared boards used across much of the S5000 range, this revision is matched to the S5381's push-button electronic speed control, so it is the correct repair part for these two machines specifically — it is not interchangeable with boards from other S5 models.

The electronic unit governs everything between the wall outlet and the motor: power-on, the stepped suction levels selected at the canister, soft-start to protect the motor windings, and thermal cut-off. A Gemini or Leo that won't switch on, ignores speed changes, or shuts down intermittently while running almost always needs this board rather than a new motor.

Replacement is a straightforward bench job for anyone comfortable opening the canister shell: the board mounts in the original carrier and connects via the factory spade terminals, with no soldering required.

Fits: Miele Gemini S5381 and Leo S5381 only.
