Pusher fan refresh
One of my pusher fans was running erratically and sometimes not at all. Wiggling the wires where they go into the fan motor would cause it to run so I assumed it was a loose wire. When I opened up the motor I discovered that wasn't the problem - the wires were well fastened. The problem was an accumulation of fine dust from the brushes wearing and causing a poor connection with the commutator. Wiggling the wires where they enter the motor also wiggles the brushes and the fan would run. As a frame of reference, I have just over 15,000 miles. So, cleaned the motor and resurfaced the commutator, which is worn and will need to be replaced at some point. The brushes have about 20 - 25% left. Motor now runs well.
There are no markings on these motors. Bob, do you have a part number for these motors or even for the brushes or commutator/armature?
