5. Pressure switch bad
Thermal overload 1. Low voltage
protector cuts out
2. Wrong gauge wire or length of
repeatedly
3. Lack of proper ventilation/room
4. Defective check valve
5. Defective unloader valve (on
6. Compressor valves failed
Tank pressure drops when 1. Loose drain valve
compressor shuts off
2. Check valve leaking
3. Loose connections at fittings,
4. Tank leaks
Compressor runs 1. Excessive air usage, compressor too
continuously and air
output is lower than
2. Loose connections at fittings,
normal/low discharge
pressure
3. Tank leaks
4. Broken valves
5. Piston ring worn
Excessive moisture in 1. Excessive water in tank
discharge air
2. High humidity
Safety valve pops open 1. Defective pressure switch
2. Defective safety valve
shutoff pressure
extension cord
temperature too high
pressure switch)
tubing, etc.
small
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.
5. Replace pressure switch.
1. Check voltage at wall outlet with voltmeter.
2. Check extension cord chart for proper extension cord usage.
3. Move compressor to well-ventilated area.
4. Repair or replace.
5. Repair or replace.
6. Replace valve assembly.
Do not disassemble check valve with
air pressure in tank; bleed tank.
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.
Do not disassemble check valve with
air pressure in tank; bleed tank.
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, (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.
4. Replace compressor valves as necessary.
5. Replace piston rings.
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 pressure switch.
2. Replace safety valve with genuine replacement part.
