How long does it run before shutting down? Is it over heating
then after it cools down it works again?
If it's over heating
then the thermal overload switch kicks in, so it could be the switch is bad. It looks like it is part of the motor
. Tried a muffin fan on another pump that was kicking off due to the thermal switch. It extended the run time but still eventually shut down. Recovered faster w/the fan blowing on the motor
Another problem w/these pumps was sensing too high of a voltage and shutting down.
