PROBLEM
POSSIBLE CAUSE
CORRECTIVE ACTION
The motor will not
run.
1. Tank pressure exceeds the preset
pressure switch limit.
2. The fuse is blown or the circuit breaker
tripped.
3. The check valve is stuck in the open
position.
4. The wire gauge in the cord is wrong or
the extension cord length is excessive.
5. There are loose electrical connections.
6. The motor’s thermal overload protection
has tripped.
7. The motor, capacitor or safety valve is
defective.
1. The motor will start automatically when
the tank pressure drops below the tank
cut-in pressure.
2. Replace the blown fuse or reset the
circuit breaker. Do not use a fuse or circuit
breaker with a higher rating than specified
for your branch circuit. Check for proper
fuse; type T fuse is acceptable. Check for
low voltage and proper extension cord size.
Disconnect other applications from the
circuit. Operate the compressor on a
dedicated circuit.
3. Remove and clean or replace.
4. Check for proper gauge and extension
cord length.
5. Contact an authorized service center.
6. Turn the air compressor off, unplug the
power cord and wait until the motor has
cooled down. Plug in the power cord only
after the motor has cooled down, waiting at
least five minutes to make sure the thermal
overload protector has recovered.
7. Have the compressor serviced by a
qualified technician.
