Probably the capacitor is bad.
It can be replaced.
Do not let motor hum, because motor is getting hot and will burn up pretty quick, or trip the reset.
Call pool company.

SOURCE: pool-spa control problem

You will probally have to replace the air tube that runs from the spa to the equiptment. With time you will build up condensation in the tube and that will cause the problem you describe.

I have century lasar pool/spa motor bn50 115volts 16.4/4.4amps 1.5hp 2spd runs on lowspeed but will not run on high speed can it be repaired or what?


I'd start by checking the relay that controls the motor first. Put a meter on it and verify that the high speed terminal is getting voltage. If not, it is the relay or something other than the motor. If the high speed terminal is getting voltage but not kicking on, a fix is possible, but you may want to weigh that against the price of a new motor.
