troubleshooting Chart
Symptom Possible Cause(s) Corrective action
Compressor will not run 1. Switch in OFF position
2. No electrical power at wall outlet
3. Compressor has reached automatic shut-
off pressure
4. Motor overheated
5. Loose electrical connection
6. ON / OFF switch bad
7. Pressure switch bad
8. Defective motor
1. Make sure compressor is plugged in and switch is ON
2. Check circuit breaker or fuse at electrical panel.
3. Release air from tank until compressor restarts
automatically
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 where temperature will
not exceed 100°F.
5. Check all electrical connections
6. Replace ON / OFF switch
7. Replace pressure switch
8. Replace pump / motor assembly
Thermal overload
protector cuts out
repeatedly 1. Lack of proper ventilation/room
temperature too high
2. Excessive air usage, compressor too small
1. Move compressor to a clean,well ventilated area where
temperature will not exceed 100°F.
2. Decrease usage or purchase unit with higher air delivery
(SCFM)
Tank pressure drops when
compressor shuts off 1. Open tank drain valve
2. Loose connections (fittings, tubing, air
hose, any connections, etc.)
3. Tank leaks
1. Close tank drain valve
2. Check all connections with soap and water solution. If a
leak is detected, tighten. Or remove fitting and apply pipe
tape to threads and reassemble.
Do not disassemble
check valve. With air in tank, bleed
tank first.
3. Check entire tank for leaks with soap and water solution
Compressor runs
continuously / air output
lower than normal 1. Excessive air usage, compressor too small
2. Open tank drain valve
3. Loose connections (fittings, tubing, air
hose, any connections, etc.)
4. Pump wore out
1. Decrease usage or purchase unit with higher air delivery
(SCFM)
2. Close tank drain valve
3. Check all connections with soap and water solution. If a
leak is detected, tighten. Or remove fitting and apply pipe
tape to threads and reassemble.
4. Replace pump / motor assembly
Excessive moisture in
discharge air 1. Excessive water in tank
2. High humidity 1. Drain tank, tilt tank to remove moisture
2. Move to area of less humidity; use air line filter
Safety valve pops open 1. Defective pressure switch
2. Defective safety valve 1. Replace pressure switch
2. Replace safety valve with genuine replacement part
