1. Check items 2-5 above.
2. Check that there is no foreign matter lodged between the contacts on the start switch.
3. Check to insure the capacitor is functioning properly.
Motor Gets Hot And Shuts Down.
1. Check for proper wiring in the motor box. The supply voltage must match the motor voltage
connections.
2. Check the voltage at the motor box, with the motor and all other loads normally on the circuit
running. It must not be significantly below the nominal voltage.
3. Check to see if the motor shaft turns without excessive resistance. Bad bearings, or a clogged
impeller can cause excessive resistance.
4. Make sure any check valves are installed in the correct direction.
5. Check that the pump impeller and the housing are not clogged or blocked.
Pump Will Not Hold A Prime.
1. Check for defective joints at all pipe fittings. They must be air tight.
