4055858270 Genuine Synchronous Motor for Electrolux Group Microwaves, Turntable Drive Motor Replacement

Microwave plate stopped turning? 4055858270 is a genuine Electrolux synchronous motor, the small motor type used to drive the turntable in Electrolux group microwave ovens. Without it, food heats in hot and cold spots because it sits still in the cavity. Synchronous motors look alike from model to model but can differ in speed, shaft and mounting, so check the number on your old motor before buying 4055858270.

Microwave turntable not spinning? Signs of a failed motor

A synchronous motor turns at a fixed speed set by the mains frequency, which suits slow, steady jobs like rotating a turntable. It sits under the cavity floor and drives the plate through a coupler. When the motor fails, the plate stays still, turns only now and then, or jerks and grinds. Before replacing it, check that the roller ring and coupler are seated correctly and not cracked, and that the plate isn't catching on something. If those are fine and the motor doesn't turn when the oven runs, the motor is the likely fault.

• Synchronous motor for an Electrolux group microwave
• Model fit not on file, match the number on your old motor

Replacing the synchronous motor

Unplug the microwave before doing anything. On many models the motor is reached through a cover plate under the oven, but on others the outer case must come off, exposing the high voltage capacitor, which can hold a lethal charge even when unplugged. If reaching the motor means removing the case, have a qualified technician do the job. Note the shaft position, fit the new motor and check the plate turns.

Questions about this part

Do I need a new coupler as well?

Not always. Check the coupler that sits on the motor shaft for cracks or rounded edges. If it's damaged, replace it along with the motor so the plate drives properly. The coupler has its own part number.
