SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Thermal overload
protector cuts out
repeatedly.
1. Low voltage
2. Clogged air filter
3. Lack of proper
ventilation/room
temperature too high
4. Check valve malfunction
5. Compressor valves
failed
1. Eliminate extension cord, check with voltmeter
2. Clean filter
3. Move compressor to well-ventilated area
4. Replace
5. Replace valve assembly
DANGER! Do not disassemble check valve with
air in tank; bleed tank.
Knocks, rattles,
excessive vibration.
1. Loose bolts, tank not
level
2. Defective bearing on
eccentric or motor shaft
3. Cylinder or piston ring is
worn or scored
1. Tighten bolts, shim tank to level position
2. Replace
3. Replace or repair if necessary
Tank pressure drops
when compressor
shuts off.
1. Loose drain cock
2. Check valve leaking
3. Loose connections
at pressure switch or
regulator
1. Tighten
2. Disassemble check valve assembly, clean or replace
3. Check all connections with soap and water solution
and tighten
Compressor runs
continuously and
air output is lower
than normal/low
discharge pressure.
1. Excessive air usage,
compressor too small
2. Clogged intake filter
3. Air leaks in piping (on
machine or in outside
system)
4. Broken inlet valves
5. Piston ring worn
1. Decrease usage
2. Clean or replace
3. Replace leaking components or tighten as necessary
4. Replace compressor valves
5. Replace piston and cylinder
Excessive moisture
in discharge air.
1. Excessive water in tank
2. High humidity
1. Drain tank
2. Move to area of less humidity; use air line filter
NOTE: Water condensation is not caused by compressor
malfunction.
Compressor runs
continuously and
safety valve opens
as pressure rises.
1. Defective pressure
switch
2. Defective safety valve
1. Replace switch
2. Replace safety valve with genuine replacement part
Excessive starting
and stopping (auto-
start)
Excessive condensation in
tank
Drain more often
Air leaking from
unloader on
pressure switch.
Check valve stuck in an
open position
Remove and replace check valve
DANGER! Do not disassemble check valve with
air in tank; bleed tank.
