Sabre 408 motor not engaging

[signman315]

Hi folks! I have a Sabre 408 and the motor is not turning on. This happens about once or twice a year and typically it's the brushes/motor itself so we keep a couple extra in stock and replace as needed. Well this time it's not the motor, I've removed the motor and tested it in a regular outlet and it's 100% fine. Upon attempting to run a job you can hear a "click" at the time when the motor is supposed to engage. I opened it up and found 2 fuses, tested those and they seem to be fine. So wondering if anybody has any tips or helpful info, thanks ahead of time

Figured it out in case any others are having the same problem....there are relays in the bottom of the box and the smallest piece of dust/etc can get in there and interrupt the connection when the relay engages. Solution = clean it up real good, blow it out with air, tap on the relays quite a bit and it will dislodge the problematic particle....back up and running!
