Have the replacement fan on hand so that you can complete the replacement quickly. The appliance overheats if it isn't cooled for an extended time.
The cooling fan is at the rear of the appliance.
To replace a cooling fan:
The fan module is held in place with spring clips. As you pull, the clips disengage and the fan stops.
As you push the fan module into the appliance, it snaps into place and automatically starts.
