I have been running my pool motor pump on 220V with the internal switch set to the 230 setting(i.e. toggle switch for 110/230) on the motor for ever.
Recently, i had some issues with the wiring and on/off switch for the pump motor, and had an electrician replace the on/off switch and replace the circuit breaker (2 pole 20 amp).
But, coincidentally, when we started the motor back up the thermal protector in the motor stopped the motor after running for about 3-4 minutes on the 220V setting. The motor is about 8 years old. But when I changed the setting on the motor to 110v , and then plugged the motor to a 110 source the motor ran without shutting off.
My question is, is it possible for the motor to go bad on the 220v setting, and but seemingly be OK on the 110V? Or is the motor gone bad and I need to replace it and go back to the 220v?
Can the motor be tested for problems in the 220v setting? Or does it speak to itself, that it shuts off on 220, but not 110? Therefore, can something be repaired to get the 220v running again without shutting off?
Thanks
