4055539474 Genuine Rangehood Fan Motor 140W for Westinghouse, Electrolux Rangehoods WRF600CS WRF900CS CS601S CS901S CS602S CS902S

Part 4055539474 is the genuine 140W fan motor assembly for Westinghouse and Electrolux group rangehoods. It has a resettable fuse and Class F insulation, and it's also known as 4055914081 and as RS60007-26WD. It suits the Westinghouse WRF600CS and WRF900CS, as well as the CS601S and CS901S, plus the CS602S and CS902S hoods. When the fan has stopped, hums or grinds, this is the motor to fit.

Rangehood fan not working or making noise

The motor drives the fan that pulls steam, smoke and grease up through the filters. Grease and heat take a toll over the years. Bearings start to whine or grind, the fan slows down, or the motor hums without turning. Because this motor has a resettable fuse, it may also cut out when it overheats and start again after cooling, which often points to clogged filters or worn bearings. If the lights work but the fan doesn't respond on any speed, the motor or its wiring is the likely fault.

Changing the rangehood motor

Turn the rangehood off at the isolator or circuit breaker, not just the switch on the hood. Remove the grease filters and any covers to reach the motor housing, and support the motor as you undo its fixings. Photograph the wiring connections before unplugging them. Hard-wired rangehoods must be disconnected and reconnected by a licensed electrician.

Questions about this part

The motor stops after a while and then restarts. Is it faulty?

That's the resettable fuse doing its job when the motor overheats. Clean or replace the grease filters and make sure the duct isn't blocked. If it keeps cutting out with clean filters, the motor bearings are likely worn and the motor should be replaced.
