When to replace: The signs that a 117478 Lamb 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 minibreaker will go bad as well as the motor. If this happens, replace the motor and then evaluate the mini breaker.

I typed the motor number in Google, MD Central was at the top of the list, went to their site, typed in the part number, filled in the purchase info at 10pm in the evening, and received an email the following morning that the motor had been shipped free, via UPS. Four days later I received the motor and installed it. I could have shipped it next day for a shipping fee, but chose not to as I knew I would be out of town for several days and wouldn't get it installed any earlier. The original motor lasted 11 years on 5700' home. So far, all is good!
