EricMN Posted September 1, 2009 Report Share Posted September 1, 2009 I recived an older Jacuzzi hot tub, 115v with a 2 speed pump /motor that is about 2 years old (so I was told). The controls are very basic and has a air swtich that turns the pump to about 4 modes, no electronic controls. The motor runs good in low speed, but when pressed to go into high speed the motor tries to start but dies and waits a about 10 seconds and tries again and fails. Is my motor bad? Or could it be the air swtich? Other? Thanks for you help! Eric Quote Link to comment Share on other sites More sharing options...

Another possibility is a severe voltage drop at start up. John Quote Link to comment Share on other sites More sharing options...
EricMN Posted September 2, 2009 Author Report Share Posted September 2, 2009 Thank you. I set up a dedicated 12 gauge wire on a 20 amp circit from the box. I will have to test the power and see what happens when it tries to go to high speed. Could it also be the starter compacitor on the motor?

Eric Possibly, and it is certainly easy enough to do a capacitance test. John Quote Link to comment Share on other sites More sharing options...
EricMN Posted September 8, 2009 Author Report Share Posted September 8, 2009 Is it possible that the promblem was due to an airlock? I was given this tub, and this was the first fill to test it out. I have never owned a tub before, so I did not realize this could happen. Would an airlock cause the motor to run fine in low speed, but cycle on high speed? or would it do it on either speed? thanks, Eric Quote Link to comment Share on other sites More sharing options...
ttrublue Posted September 8, 2009 Report Share Posted September 8, 2009 Airlock would be either speed Quote Link to comment Share on other sites More sharing options...
