Intermatic Pool Timer Wiring

**sjeffers01** · 05-25-2014 07:31 PM

I guess I was hoping for a simple solution to fix the over heating problem. I am going to run the pump until the new one arrives. I set the tripper pins on the timer to run early morning for 2 hours, late afternoon 1/2 hour, and for 2 hours at midnight. I go swimming in the late afternoon so I can shut the pump off if it gets too hot. The other tripper pins are set to run during the coolest periods. I hope the new pump runs as quiet as the Whisperflo. I may have a licensed pool technician check the wiring and the rest of the system. I have to review my options and decide the best way to go. Thank you for your assistance. If any forum subscribers have had the same problem of overheating that was not due to issues with the main breaker or GFCI, it would be interesting to see what was done to identify and fix the problem.

Have you inspected the impeller and diffuser? Any obstruction would cause the motor to overheat and trip the thermal sensor. Also, I don't think you ever answered my other question about pump noise. Is is screeching or whining?

I did check it for obstruction and there wasn't anything, I am not sure about diffuser but I will check it. The pump is really quiet. No screeching or whining.

@Pappy: pumps wired 120v but fed 240v can die fairly spectacularly . . . but they don't run for awhile and then shut off. I'm not sure I've seen a pump wired 240v and fed 120v, but I'm guessing it would just hum till it overheated.
