The fuses blow or circuit
breaker trips repeatedly.
□ The incorrect fuse type is
being used.
□ Check for the proper fuse.
□ Use a time-delay fuse. Disconnect
other electrical appliances from the
circuit or operate the compressor on
its own branch circuit.
□ The wrong gauge wire or
length of extension cord is
used.
□ Check for the proper gauge wire and
cord length.
□ There is a defective check
valve or unloader.
□ Bring the compressor to a service
center.
Problem Possible Cause Solution
The thermal overload protector
cuts out repeatedly.
□ There is low voltage from the
power source.
□ Call an electrician.
□ There is a lack of proper
ventilation, or the room
temperature is too high.
□ Move the compressor to a well-
ventilated area.
□ The wrong gauge wire or
length of extension cord is
being used.
□ Check for proper gauge wire and cord
length.
The air receiver pressure
drops when the compressor
shuts off.
□ The connections (fittings,
tubing, etc.) are loose and
leaking.
□ Check all connections with a soap and
water solution and tighten.
□ The drain valve is loose or
open.
□ Tighten the drain valve.
□ The check valve is leaking. □ Bring the compressor to a service
center.
There is excessive moisture
in the discharge air.
□ There is excessive water in
the air tank.
□ Drain the tank.
□ The compressor is working
under a high humidity
environment.
□ Move the compressor to an area of
less humidity; use an air line filter.
The compressor continuously
runs.
□ The pressure switch is
defective.
□ Bring the compressor to a service
center.
□ An excessive amount of air is
being used.
□ Decrease the air usage; the
compressor is not large enough for
the tool’s requirement.
The air output is lower than
normal.
□ The inlet valves are broken. □ Bring the compressor to a service
center.
□ The connections (fittings,
tubing, etc.) are loose and
leaking.
□ Tighten the connections.
