Oilless Compressors

Troubleshooting Chart

Symptom Possible Cause(s)
Compressor will 1. Switch in OFF position
not run
2. No electrical power at wall outlet
3. Compressor has reached automatic
shut-off pressure
4. Motor overheated
5. Pressure switch bad
Thermal overload 1. Lack of proper ventilation / room
protector cuts out temperature too high
repeatedly
2. Compressor valves failed
Knocks, rattles, 1. Tank not level
excessive vibration
2. Defective bearing on eccentric or
motor shaft
3. Cylinder or piston ring is worn or
scored
Tank pressure 1. Loose drain valve
drops when
2. Check valve leaking
compressor shuts
3. Loose connections (fittings, tubing,
off
etc.)
Compressor runs 1. Excessive air usage, compressor too
continuously and small
air output is lower
2. Loose connections (fittings, tubing,
than normal / low
etc.)
discharge pressure
3. Broken inlet valves
4. Piston ring worn
Excessive moisture 1. Excessive water in tank
in discharge air
2. High humidity
Compressor runs 1. Defective pressure switch
continuously and
2. Defective safety valve
safety valve opens
as pressure rises
Excessive starting 1. Excessive condensation in tank
and stopping
2. Loose connections (fittings, tubing,
etc.)

Corrective Action
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. Replace pressure switch
1. Move compressor to a clean,well ventilated area where
temperature will not exceed 100° F.
2. Replace pump assembly
1. Shim tank to level position
2. Replace pump assembly
3. Replace pump assembly
1. Tighten drain valve
2. Replace check 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.
Do not disassemble check valve.
With air in tank, bleed tank first.
1. Decrease usage or purchase unit with higher air delivery
(SCFM)
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.
3. Replace pump assembly
4. Replace piston assembly
1. Drain tank, tilt tank to remove moisture
2. Move to area of less humidity; use air line filter
NOTE: Water condensation is not caused by compressor
malfunction
1. Replace pressure switch
2. Replace safety valve with genuine replacement part
1. Drain more often
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.
