Troubleshooting Chart
Symptom Possible Cause(s) Corrective Action
Compressor will not
run
1. Switch in OFF position 1. Make sure compressor is plugged in and switch is ON.
2. No electrical power at wall
outlet
2. Check circuit breaker or fuse at electrical panel.
3. Compressor has reached
automatic shutoff pressure
3. Release air from tank until compressor restarts
automatically.
4. Motor overheated 4. Allow compressor to cool for approximately 30 minutes so
thermal overload switch will reset. Make sure compressor is
run in a clean, well-ventilated area.
5. Pressure switch bad 5. Replace pressure switch.
Thermal overload
protector cuts out
repeatedly
1. Low voltage 1. Check voltage at wall outlet with voltmeter.
2. Wrong gauge wire or length of
extension cord
2. Check extension cord chart for proper extension cord
usage.
3. Lack of proper ventilation / room
temperature too high
3. Move compressor to well-ventilated area.
4. Defective check valve 4. Repair or replace.
5. Defective unloader valve (on
pressure switch)
5. Repair or replace.
6. Compressor valves failed 6. Replace valve assembly.
Do not disassemble check valve with
air pressure in tank; bleed tank.
Tank pressure drops
when compressor shuts
off
1. Loose drain valve 1. Tighten.
2. Check valve leaking 2. Remove check valve. Clean or replace.
3. Loose connections at fittings,
tubing, etc.
3. Check all connections with soap and water solution. If a
leak is detected, (1) tighten or (2) remove fitting and apply
pipe tape to threads and reassemble.
4. Tank leaks 4. Check tank for leaks with soap and water solution. If leak is
detected, tank must be replaced with genuine replacement
part.
Do not disassemble check valve with
air pressure in tank; bleed tank.
Compressor runs
continuously and air
output is lower than
normal / low discharge
pressure
1. Excessive air usage, compressor
too small
1. Decrease usage or purchase unit with higher air delivery
(SCFM).
2. Loose connections at fittings,
tubing, etc.
2. Check all connections with soap and water solution. If a
leak is detected, (1) tighten or (2) remove fitting and apply
pipe tape to threads and reassemble.
3. Tank leaks 3. Check tank for leaks with soap and water solution. If leak is
detected, tank must be replaced with genuine replacement
part.
4. Broken valves 4. Replace compressor valves as necessary.
5. Piston ring worn 5. Replace piston rings.
Excessive moisture in
discharge air
1. Excessive water in tank 1. Drain tank.
2. High humidity 2. Move to area of less humidity; use air line filter.
NOTE: Water condensation is not caused by compressor
malfunction.
Safety valve pops open 1. Defective pressure switch 1. Replace pressure switch.
2. Defective safety valve 2. Replace safety valve with genuine replacement part.
