TROUBLESHOOTING
PROBLEM
Water in discharge
air / tank
Motor hums and
runs slowly or not
at all
Reset mechanism
cuts out repeatedly
or circuit breaker
trips repeatedly
POSSIBLE CAUSE
Normal operation. The
amount of water increases
with humid weather
1. Low voltage
2. Use of extension cord
3. Too many devices on
same circuit
4. Loose electrical
connections
5. Malfunctioning pressure
switch - contacts will not
close
6. Malfunctioning check
valve
7. Defective unloader valve
on pressure switch
8. Defective motor
capacitor(s)
9. Defective motor
1. Lack of proper
ventilation / room
temperature too high
2. Too many devices on
same circuit
3. Restricted air intake
4. Loose electrical
connection
5. Pressure switch shut-off
pressure set too high
CORRECTIVE ACTION
1. Drain tank more often. At least daily.
2. Add a filter to reduce the amount of water in the
air line.
1. Check incoming voltage. It should be
approximately 230 volts. Motor will not run
properly on 208 volts. Low voltage could
be due to wires (from electrical source to
compressor) being too small in diameter and /
or too long. Have a qualified electrician check
these conditions and make repairs as needed.
2. Do not use an extension cord. Use longer air
hose with larger diameter.
3. Limit the circuit to the use of compressor only
4. Check all electrical connections.
5. Replace pressure switch.
6. Replace check valve.
DANGER
Risk of Explosion. Do not
disassemble check valve with air
pressure in tank.
7. Replace unloader valve.
8. Replace capacitor(s).
9. Replace motor.
1. Move compressor to well-ventilated area.
2. Limit the circuit to the use of only the air
compressor.
3. Clean or replace filter element.
4. Check all electrical connections.
5. Replace pressure switch.
