When to replace:
The signs that a 117123 Ametek motor needs to be replaced include: mini breaker popping, electrical smell, excessive blue sparks seen from motor top, you only hear a click, motor shuts down on its own but works later, or its life of 900-1,200 hours has been used up. (If you don't hear a click, then your relay most likely needs to be replaced and your motor may be fine). Five percent of the time, the mini breaker will go bad as well as the motor. If this happens, replace the motor and then evaluate the mini breaker.
