Troubleshooting

Symptom
The motor will not start but
fuses do not blow.
The fuses blow or overload
protector trips when the
motor starts.
Fuses blow or overload
protector trips when the
motor is running.
Probable Cause
There is no voltage at the fuse box.
There is no voltage at the pressure switch
There is no voltage at the control box
Cable or splices are bad.
The control box is incorrectly wired.
The fuse or time delay fuse size is wrong.
The wire size is too small.
The starting capacitor is defective or blown.
The voltage is either too low or high.
The cable leads are not correctly connected to
the control box.
There is a broken wire in the control box.
The pump or motor is stuck or binding.
The voltage is either too low or too high.
The ambient (atmospheric) temperature is
high.
Control box with wrong voltage or horsepower
rating.
The wire size is too small.
Cable splices or motor leads grounded,
shorted, or open.
Corrective Action
Replace blown fuses.
Replace the faulty pressure switch.
Rewire the supply to the control box.
Consult a licensed electrician or serviceman.
Reconnect the control box correctly (see wiring
diagrams).
Check the fuse size against the Recommended Fusing
Data tables in the Wiring section of this manual. Install
the correct fuse or time delay fuse.
Check the wire size against the tables in the Wiring
section of this manual. Install the correct size wire.
Check the control box to see if starting capacitor has
blown out. Replace the starting capacitor.
Check that line voltage is within ±10% of the nameplate
rated voltage while the motor is running. If voltage
variation is greater than ±10%, call the power company to
adjust the voltage.
Check the control box wiring diagram against the
incoming power hookup. Check drop cable color coding.
Reconnect the drop cable so the cable color code
matches the motor lead color code.
Examine all connections and wiring in the control box.
Disconnect the power and repair or replace the faulty
wire.
Check for a locked rotor in the pump. If necessary, pull
the pump (make all possible above ground checks first). If
the pump is locked, replace it. Clean the well of all sand
or lime before reinstalling pump.
Check that line voltage is within ±10% of the nameplate
rated voltage while the motor is running. If voltage
variation is greater than ±10%, call the power company to
adjust the voltage.
Check the temperature of the control box. Do not mount
the control box in direct sunlight.
Compare voltage and horsepower on the motor nameplate
with those given on the control box nameplate or on the
circuit diagram inside the control box cover. Replace the
control box if the numbers do not match.
Check the wire size against the table in the Wiring section
of this manual. Install the correct size wire.
Consult a licensed electrician or qualified serviceman. Do
not attempt to disassemble the pump or motor.
