Changing a Bubendorff roller shutter capacitor: a good idea?

Many of you look for capacitors when your roller shutters show signs of weakness. Various articles on the Internet testify to successful changes, at a lower cost, to repair roller shutter motors.

Lacentrale-eco does not sell capacitors.

Nevertheless, for the sake of repairability , preservation of resources and durability , we invite you to contact ma-carte-electronics .

There is no commercial link between Lacentrale-éco and ma-carte-electronics.

The role of the capacitor for a roller shutter motor

Capacitor is an electrical component that stores energy in the form of an electric field . In the case of a roller shutter motor, the capacitor is used to give an initial pulse to the motor when it starts. It is this impulse that allows the motor to start rotating.

The capacitor is connected to the motor winding, and when charged, it generates a magnetic field that spins the motor rotor. Once the motor is started, the capacitor continues to supply alternating current to keep the motor spinning.

If the capacitor is faulty or worn, the motor may have difficulty starting or not start at all. In some cases, the motor may run, but with reduced efficiency or irregular rotation.

It is therefore essential that the capacitor is in good working order for the roller shutter motor to work properly.

What does Bubendorff say about capacitor replacement?

The manufacturer advises against replacing capacitors on your own. Their analysis of after-sales service returns led Bubendorff to replace entire motors, not components.

Indeed, this can pose lasting reliability problems when parts are changed in isolation. The manufacturer also does not sell the electronic card as a spare part.

If we took an example, if you replace a small part of your car which has 250,000 km, it may allow you to drive again.

By having a certain risk that other elements of your engine break, surely, shortly afterwards. It's the same for the motor of your roller shutter.

The price of a capacitor

Depending on the model, count from around 8 to 30 € , depending on the model and the seller. This does not include the repair itself, only the price of the component, excluding delivery. In addition, the tools required can quickly increase the bill.

We advise you to buy them on ma-carte-electronique, a serious company.

Capacity (indicative) of the capacitor

The capacitance of the capacitor needed may vary depending on the specific motor and its use. It is always recommended to check the manufacturer's specifications before proceeding with a replacement.
