8581250020337 Genuine Interference Suppression Capacitor for Electrolux Group Clothes Dryers, Electrolux 1250020334 (1250020-33/4)

Interference capacitor 8581250020337 is a genuine Electrolux part, shown in the older dashed format as 1250020-33/4, or 1250020334 in full. It's a suppression capacitor, the kind that filters electrical noise from a motor or the mains supply, and we file it with Electrolux group dryer parts. Values and terminal layout aren't on file, so compare the markings on your old capacitor before ordering.

What an interference capacitor does

Motors, switches and relays create small electrical spikes as they run and switch. An interference suppression capacitor soaks up that noise so it doesn't feed back into the household wiring, where it can upset radios, TVs or other appliances. When one fails it can go open circuit with no obvious sign, or it can short, tripping the safety switch, blowing a fuse or leaving a burnt smell. A split case or a bulging body is a clear reason to replace it.

Replacing the capacitor safely

Unplug the dryer before opening the cabinet, and wait a few minutes for any stored charge to bleed away. Photograph the leads and any earth connection, then remove the old capacitor. Fit the new one in the same place, connect each lead to the matching terminal, secure the earth, and refit all covers before plugging back in.

Questions about this part

Can I use any capacitor with the same value?

Suppression capacitors are safety rated parts made for connection across the mains, so they aren't interchangeable with ordinary capacitors. Matching the genuine part number is the simplest way to get the right type, rating and fixing.
