I went to start the MM20 today and it was non-functional.
Single phase 240v setup.
I started investigating the point of failure and have discovered that:
-The switch appears to be functional. Each motor lead shows 120v but the motor does not hum when the switch is pressed.
-The capacitors are good according to my multimeter. For posterity I swapped them to new capacitors and they’re also good.
I’m now wondering if there is an internal overload that requires taking the motor apart to access but I’m unsure.
The motor is a 100L frame euro motor made by Motek.
Resistance across the leads is 0.7 ohms. This seems low compared to other motors I have.
Resistance to ground from the motor leads both show OL which I believe is s good sign.
