Al, got a new toggle switch, wired it up and put the motor back together. The motor will start on high speed but will not start in low speed, just hums. However, When the motor is running on high and I flip the switch to low it continues to run on low with no problem. There is only one capacitor mounted on top of the exterior of the motor housing. The centrifugal switch seemed to move freely and I cleaned the contacts off with some emery cloth. Any ideas? Thanks again
