    Pump not working again suspect bad temp control

    Pump not working suspect bad temp control. See picture of Penn A19AAF temp control and timer setup. Basic setup..Timer has a toggle switch at bottom that I flip to change speeds on pump (slow during normal operation fast for vacuuming).

    I (or rather my electrician friend) installed timer, and new pump about a year ago. The pump quit and tripped the breaker in November. Close examination showed a wire had arced between timer and temp controller so we replaced wires and toggle switch circuit and the pump worked normally.

    Now the pump stopped working but did not trip the breaker. This is becoming a chronic problem. Seems to be rain related but does not happen every time it rains.

    Electrician friend is out of town for a week so trying to diagnose and line up parts if need. My instinct says replace the temp switch because it is at least 10 years old and made in USA. I think Johnson stopped making them in USA 20 years ago.

    What advice can someone out there in TFP land give me? Penn A19AAFs seem to be hard to get. Can someone suggest a substitute?

    I'm not really sure what the purpose for the stat is in your situation. I do refrigeration and use these all the time

    If you suspect this stat as being your problem, why not just jump it out and see if it corrects your timer/pump issue?

    Pool pump motor is cooked. 14 months old. Time to call Hawayrd and see how they handle the problem.
