I have a spa with a IN.YJ-2 control board. Everything works except when motor high speed is selected, the motor only runs for 2-3 seconds and then stops. After 5 or so seconds it tries again and runs for 2-3 seconds and stops. I think the high speed portion of the pump motor has failed and is kicking out on over current. It also makes a funny noise like the windings are loose. Motor and pump work fine when in circulation mode. Anybody have thoughts?
