TROUBLESHOOTING CHART
SYMPTOM
Tank pressure
drops when
compressor
shuts off
Compressor runs
continuously and
air output is lower
than normal/low
discharge pressure
Excessive moisture
in discharge air
Compressor runs
continuously and
safety valve opens
as pressure rises
Excessive starting
and stopping
(auto start)
Air leaking from
unloader valve
on pressure switch
POSSIBLE CAUSES
1. Loose drain valve
2. Check valve leaking
3. Loose connections
at fittings, tubing, etc.
4. Tank leaks
1. Excessive air usage,
compressor too small
2. Clogged intake filter
3. Loose connections
at fittings, tubing, etc.
4. Tank leaks
5. Broken valves
6. Piston ring worn
1. Excessive water in tank
2. High humidity
1. Defective pressure switch
2. Defective safety valve
1. Excessive condensation in tank
2. Loose connections at
fittings, tubing, etc.
3. Tank leaks
1. Check valve stuck in an
open position
2. Unloader valve stuck
in open position
CORRECTIVE ACTION
1. Tighten.
2. Remove check valve. Clean or replace.
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. Check tank for leaks with soap and water solution.
If leak is detected, tank must be replaced with
genuine replacement part.
DANGER
valve with air in tank; bleed tank
1. Decrease usage or purchase unit with higher air
delivery (SCFM).
2. Clean or replace.
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. Check tank for leaks with soap and water solution.
If leak is detected, tank must be replaced with
genuine replacement part.
5. Replace compressor valves as necessary.
6. Replace piston and cylinder.
1. Drain tank.
2. Move to area of less humidity; use air line filter.
NOTE: Water condensation is not caused
by compressor malfunction.
1. Replace 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, (1) tighten or (2) remove fitting
and apply pipe tape to threads and reassemble.
3. Check tank for leaks with soap and water solution.
If leak is detected, tank must be replaced with
genuine replacement part.
DANGER
valve with air in tank; bleed tank
1. Repair or replace check valve.
2. Repair or replace unloader valve.
DANGER
valve with air in tank; bleed tank
