O'man, that jogged a question I've had. Just how much rpm does an electric motor have to have before the run capacitor has the fun and the start cap is finished?

Tommy , the motor on my table saw hummed also turned out to be the switch itself . The cap was good but the contacts in the switch were bad . Dan

LW according to the Pentek page you so graciously provided the motor once reaching operating rpm should disconnect the start capacitor and use the run capacitor. so it looks as though I need to spin it at 3400 rpm to see if it will run off the run capacitor. Spin Spin I'm disassembling the drive belt right now.

Your just getting what comes around thru the motor and back to the other line. Assuming your checking from ground. If your motor is wired for 230 you should get 240 across the two wires. Like I said in my first post reset your TWO breakers first !

Yes, you should be getting 240-something across the motor leads.
If the breakers are passing 240v across the lugs then I'm betting the pressure switch has a bad contact.
