Are the relays perment on the board or are they seperate from the main board? If they are mounted to the board, you will need to replace the board. Sounds like you are getting a call to the relay but none leaving so this would indicate that you have a bad relay switch.

If your motor only works on low speed and not on high speed first check to see if you have the proper voltage to high speed. Check with a voltmeter or multimeter, check from common on the motor to high speed on the motor at the switch. If you have the proper voltage then you have an open winding on high speed and the motor needs replaced. If you don’t have the proper voltage or any volts, then the switch is bad and needs replaced. This also will be the same if, medium speed won’t work and low speed does.

SOURCE: we have a champion mastercool
Hi, I am surprised Home Depot didn't have one as this is a very common motor. I don't know where you are from, but if you look on lone for Grangers supply, or Motion industries, they will have this motor for sure. They both are large suppliers of anything you need in this line of parts. This is a very common motor, totally sealed bearings and body with adjustable sheave, ( pulley ). Please let me know what you find. I will be here to help.
