Troubleshooting (continued)
Problem
The motor hums and runs
slowly, or the motor does
not run at all.
The reset mechanism cuts
out repeatedly or the circuit
breaker trips repeatedly.
The tank does not hold
pressure when the
compressor is off and the
shut off valve is closed.
The pressure switch
continuously blows air out
the unloader valve.
There is excessive
vibration.
Possible Cause
□ The voltage is low.
□ There are too many devices on same
the circuit.
□ The electrical connections are loose.
□ The pressure switch is malfunctioning
- the contacts will not close.
□ The check valve is malfunctioning.
□ The unloader valve on the pressure
switch is defective.
□ The motor capacitor(s) are defective.
□ The motor is defective.
□ Use of an extension cord
□ There is not proper ventilation for
the air compressor unit, or the room
temperature too high.
□ There are too many devices on the
same circuit.
□ The air intake is restricted.
□ The electrical connections are loose.
□ The pressure switch shut-off pressure
is set too high.
□ The check valve is malfunctioning.
□ The unloader valve on the pressure
switch is defective.
□ The motor capacitor(s) are defective.
□ The motor is defective.
□ Use of an extension cord
□ There are air leaks in the fittings,
tubing on the compressor, or the
plumbing outside the unit.
□ The check valve is worn.
□ Check the tank for cracks or pin
holes.
□ The check valve is malfunctioning.
□ The fasteners on the pump or the
motor are loose.
□ The belt needs to be replaced.
□ The belt needs to be aligned.
Solution
□ Check incoming voltage. It should be approximately 120 volts.
□ Limit the circuit to the use of the compressor only.
□ Check all the electrical connections.
□ Replace the pressure switch.
□ Replace the check valve. Do not disassemble the check valve with
air pressure in the tank.
□ Replace the unloader valve.
□ Replace the capacitor(s).
□ Replace the motor.
□ Do not use an extenstion cord. Use a longer air hose with a larger
diameter.
□ Move the compressor to a well-ventilated area.
□ Limit the circuit to the use of only the air compressor.
□ Clean or replace the air filter element.
□ Check all the electrical connections.
□ Replace the pressure switch.
□ Replace the check valve. Do not disassemble the check valve with
air pressure in the tank.
□ Replace the unloader valve.
□ Replace the capacitor(s).
□ Replace the motor.
□ Do not use an extenstion cord. Use a longer air hose with a larger
diameter.
□ Listen for escaping air. Apply soap solution to all fittings and
connections. Bubbles will appear at points of leakage. Tighten or
replace leaking fittings or connections. Use pipe thread sealant.
□ Replace the check valve. Do not disassemble the check valve with
air pressure in the tank.
□ Replace the tank. Never try to repair a damaged tank.
□ Replace the check valve if the unloader valve on the pressure
switch bleeds off constantly when the unit shuts off. Do not
disassemble the check valve with air pressure in the tank.
□ Tighten the fasteners.
□ Replace the belt. Make sure to use the correct size.
□ Align the flywheel and the pulley.
