Troubleshooting Chart
Symptom Possible Cause(s)
Compressor will 1. No electrical power
not run
2. Breaker open
3. Pressure switch bad
4. Motor over worked
5. Tank pressure above cut-in
Fuses blow/circuit 1. Incorrect size fuse, circuit
breaker trips overloaded
repeatedly
2. Extension cord usage - wrong
gauge wire and/or too long.
3. Worn check valve
4. Defective unloader valve (on
pressure switch)
5. Defective motor capacitor(s)
6. Defective motor
Tank pressure 1. Loose connections (fittings, tubing,
drops when etc.)
compressor shuts
off
2. Open tank drain valve
3. Tank leaks
Compressor runs 1. Excessive air usage
continuously
and/or air output
2. Clogged intake filter
is lower than
3. Open tank drain valve
normal/low
4. Air leaks in piping (on machine or
discharge pressure
in outside system)
5. Piston ring worn
6. Broken valve (in pump)
7. Tank leaks
8. Defective pressure switch
Excessive moisture 1. Excessive water in tank
in discharge air
2. High humidity
Corrective Action
1. Plugged in? Switch on? Check fuse/breaker.
2. Reset, determine cause of problem.
3. Replace.
4. Turn off, let cool, turn on.
5. Bleed tank pressure down to cut-in.
1. Check for proper fuse, use time-delay fuse. Disconnect other
electrical appliances from circuit or operate compressor on
its own branch circuit.
2. Remove extension cord or refer to Extension Cord Chart on
page 4.
3. Replace check valve.
Do not disassemble check valve
with air in tank; bleed tank.
4. Replace unloader valve.
5. Replace capacitor(s).
6. Replace motor.
1. Check all connections with soap and water solution. Tighten;
or remove and apply pipe dope or pipe tape to the threads,
then reassemble.
2. Close tank drain valve.
3. Check tank for leaks with soap and water solution. If leak is
detected, tank must be replaced with genuine replacement
part.
1. Decrease air usage; compressor not large enough for air
requirement.
2. Clean or replace filter.
3. Close tank drain valve.
4. Check all connections with soap and water solution. Tighten;
or remove and apply pipe dope or pipe tape to the threads,
then reassemble.
5. Replace piston and cylinder.
6. Replace valve.
7. Check tank for leaks with soap and water solution. If leak is
detected, tank must be replaced with genuine replacement
part.
8. Replace switch.
1. Drain tank.
2. Move to area of less humidity; use air line filter.
