check your motor brushes to make sure one isn't stuck

if the feed motor runs then the cord and Thermal circuit Breaker is OK.

Check for loose terminal/screws inside the motors junction box.
if you have a multi-meter it should not take more then 10 minutes to find the issue.
can not rule out a Thermal circuit Breaker inside the motor.

You'll have wires that come from the plug and go into the switch. Black should be "hot" coming from the skinny spade on the plug, white from the wide spade on the plug. 120v, correct?

With sander unplugged, check for continuity on/off to figure out how the switch works. Are there two switches on the other side? More pics will help us help you.

Only a start and stop buttons (2 total). The start button doesn’t depress well.

I took the meter and the volts ‘in’ are at 120. Swaps meter leads to the other terminals on the ‘out’ side, results are zero power on the terminals going to the motors. I called Grizzly tech support and they agreed it is most likely a bad switch. This approach is also what the troubleshooting section of the user manual states as the first step when this problem occurs.

I’ll post results after the new switch is installed. Thx for all the suggestions thus far.

Default Conclusion

New switch did the trick. Thanks to all that contributed their ideas. I appreciate the time it took you all to respond.
