symptom
Compressor will not run
Fuses blow/circuit breaker
trips repeatedly
Tank pressure drops
when compressor shuts
off
Compressor runs
continuously and/or air
output is lower than
normal/low discharge
pressure
Excessive moisture in
discharge air
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 1. Check for proper fuse, use time-delay fuse.
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
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.
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
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.
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
