4055558516 Genuine Compressor Drive Electronics for Electrolux Group Fridges, Inverter Compressor Drive Board

This is genuine Electrolux group compressor drive electronics, part number 4055558516. Fridges with a variable speed, or inverter, compressor use a drive module like this to start the compressor and control its speed. If the drive fails, the compressor won't run, so the fridge and freezer both warm up even though the lights and fans may still work. Confirm 4055558516 on your old module or parts list before buying.

Fridge not cooling but the lights are on?

Inverter compressors can't run straight off mains power. The drive electronics take instructions from the main control board and power the compressor at the speed needed, slowing it down once the cabinet reaches temperature. A failed drive often leaves a fridge that is silent and warm, a compressor that tries to start and clicks off, or an error code on the display. The same symptoms can come from the compressor itself, the main board or a wiring fault, so testing by a qualified refrigeration technician is the best way to avoid buying the wrong part.

Fitting the drive module

Unplug the fridge at the wall and wait a few minutes before touching the module, as charge can remain stored in the electronics. The drive is usually mounted near the compressor at the back of the cabinet. Photograph every plug and wire before disconnecting, then fit the new unit in the same position. A qualified technician is the best person for this job.

Questions about this part

Will this fix my fridge if the compressor is faulty?

No. Part 4055558516 is the drive electronics, not the compressor. If the compressor itself has failed, a refrigeration technician will need to replace it. Testing first helps you avoid ordering the wrong part.
