Possible Cause(s)
1. No electrical power
2. Breaker open
3. Pressure switch bad
4. Motor over worked
5. Tank pressure above cut-in
1. Incorrect size fuse, circuit
overloaded
2. Extension cord usage - wrong
gauge wire and/or too long.
3. Worn check valve
4. Defective unloader valve (on
pressure switch)
5. Defective motor capacitor(s)
6. Defective motor
1. Loose connections (fittings,
tubing, etc.)
2. Open tank drain valve
3. Tank leaks
4. Worn check valve
1. Excessive air usage
2. Clogged intake filter
3. Open tank drain valve
4. Air leaks in piping (on machine
or in outside system)
5. Piston ring worn
6. Broken valve (in pump)
7. Tank leaks
8. Defective pressure switch
1. Excessive water in tank
2. High humidity
Corrective Action
1. Plugged in? Switch on? Check fuse/breaker
2. Reset, determine cause of problem
3. Replace
4. Turn off, let cool, turn on.
5. Bleed tank pressure down to cut-in.
1. Check for proper fuse, use time-delay fuse. Disconnect
other electrical appliances from circuit or operate
compressor on its own branch circuit.
2. Remove extension cord or refer to Extension Cord Chart on
page 4.
3. Replace check valve.
Do not disassemble check valve with
air pressure in tank; bleed tank.
4. Replace unloader valve.
5. Replace capacitor(s)
6. Replace motor
1. Check all connections with soap and water solution.
Tighten; or remove and apply pipe dope or pipe tape to
the threads, then reassemble.
2. Close tank drain valve
3. Check tank for leaks with soap and water solution. If
leak is detected, tank must be replaced with genuine
replacement part.
4. Replace check valve
Do not disassemble check valve with
air pressure in tank; bleed tank.
1. Decrease air usage; compressor not large enough for air
requirement
2. Clean or replace filter
3. Close tank drain valve
4. Check all connections with soap and water solution.
Tighten; or remove and apply pipe dope or pipe tape to
the threads, then reassemble.
5. Replace piston and cylinder.
6. Replace valve
7. Check tank for leaks with soap and water solution. If
leak is detected, tank must be replaced with genuine
replacement part.
8. Replace switch
1. Drain tank
2. Move to area of less humidity; use air line filter
