Check electric power supply into the pool pump motor for correct voltage. If the voltage is correct, turn off electric power supply and open the pool pump’s wet end and check that the impeller and motor’s shaft turns freely. If not, motor may need to be replaced. If shaft turns freely, remove motor capacitor and meter it for continuity. Replace the pool motor capacitor if not working.
