What to do if Pentair P42B0007A2-01 Engine starts then blows fuse?
If the Pentair Engine starts and runs, but then blows a fuse or trips the circuit breaker, it could be due to incoming voltage being more than 10% high or low. Verify if the voltage in the motor cable is too high or low, and consult your power company. Another potential cause is sand in the well, in which case you should pull the pump and clean the well.
Why does my Pentair Engine start but then blow fuses?
If the Pentair Engine starts but then the fuses blow or the circuit breakers trip, there are several potential causes: * **Wrong voltage:** Ensure the nameplate rated voltage matches the nominal power supply, and that the actual supply voltage is within ±10% of the nameplate voltage. * **Incorrect fuses or relay:** Install the correct fuses or relay. * **Incorrect connections:** Reconnect the motor wires correctly. * **Locked rotor or pump:** Ensure the motor is at least 10ft above the bottom of the well and check the well for sand. * **Insufficient insulation on motor cables:** Install new motor cables and recheck resistance with a Megohmeter.
What to do if Pentair P42B0007A2-01 Engine doesn't start and the fuse blows?
If the Pentair Engine does not start, but the fuse blows or the circuit breaker trips, it could be due to a locked rotor or pump. You should check for sand in the well and ensure that the motor is at least 10ft above the bottom of the well. Pull the pump and check for any mechanical obstructions in the pump and ensure the motor rotates freely.
