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