Thread: Pump won't turn on

    Pump won't turn on

    Went out to vacuum, but nothing happened when I turned pump on. Switched outlets, nothing, though radio works from both sides. The motor felt hot to touch (but it may always feel that way since it's sitting in hot sun!). Now, about half hour before this, my daughter had plugged a radio into the outlet right next to the one the pool pump is plugged in to. When she plugged it in, she said the pump shut off (at least she thinks it did. She wasn't paying much attention to it as it wasn't important at the time). Our AC unit is right next to it, so it could have shut off and that may be what she heard. But she thinks it was the pump, which is on a timer, so it could have coincidentally been ready to switch off at that time).

    Do motors tend to overheat? Any other ideas to try?? Really need to vacuum....had storm last night (!) and lots of stuff in pool. Thanks!

    Yes motors can overheat, usually due to a problem with the bearings. When they do overheat, the thermal limiter switch trips and the motor shuts. However, after it cools, you can usually turn it back on for at least a few seconds until it trips again. If it doesn't turn on or at least hum after it cools, then it is probably something else.

    It could also be a GFCI that tripped although the radio should have turned off too. Does the pump have a GFCI?

    Im trying to find the manual, but any idea where I would look on the pump to see if it does have a GFCI?

    It isn't on the pump itself but a GFCI is either a special circuit breaker in the panel for a direct wired pump or an outlet for a plug in type pump.
