Troubleshooting Chart

Symptom	Possible Cause(s)		Corrective Action
Compressor will not run	1 . Switch in OFF position		1	. Make sure compressor is plugged in and switch is ON.
	2	. No electrical power at wall outlet	2	. Check circuit breaker or fuse at electrical panel.
	3	. Compressor has reached automatic	3	. Release air from tank until compressor restarts
		shutoff pressure		a u t o m a t i c a l l y .
	4	. Motor overloaded	4	. Allow compressor to cool for approximately 30
				minutes. To reset, turn pressure switch to OFF, then
				AUTO. Make sure compressor is run in a clean, well-
				ventilated area.
	5	. Pressure switch bad	5	. Replace pressure switch.
Motor hums but cannot	1 . Defective check valve		1	. Repair or replace.
run or runs slowly	2 . Defective unloader valve (on pressure		2	. Repair or replace.
		s w i t c h )	3	. Check voltage at wall outlet with voltmeter.
	3	. Low voltage
	4	. Loose electrical connections	4	. Check all electrical connections.
	5	. Wrong gauge wire or length of	5	. Check extension cord chart for proper extension cord
		extension cord		u s a g e .
	6	. Defective motor capacitor	6	. Replace capacitor.
	7	. Shorted or open motor winding	7	. Replace motor assembly.

Do not disassemble check valve with air in tank; bleed tank

Flow blows/circuit breaker trips repeatedly

1	. Incorrect fuse size, circuit overloaded	1	. Check for proper fuse. Use time delay fuse.
			Disconnect other electrical appliances from circuit or
			operate compressor on its own branch circuit.
2	. Wrong gauge wire or length of	2	. Check extension cord chart for proper extension cord
	extension cord		u s a g e .
3	. Defective check valve	3	. Repair or replace.
4	. Defective unloader valve (on pressure	4	. Repair or replace.
	s w i t c h )	5	. Replace capacitor.
5	. Defective motor capacitor
6	. Motor shorted or seized	6	. Replace motor assembly.

1	. Low voltage	1	. Check voltage at wall outlet with voltmeter.
2	. Wrong gauge wire or length of	2	. Check extension cord chart for proper extension cord
	extension cord		u s a g e .
3	. Clogged intake filter	3	. Clean or replace filter.
4	. Lack of proper ventilation/room	4	. Move compressor to well-ventilated area.
	temperature too high	5	. Repair or replace.
5	. Defective check valve
6	. Defective unloader valve (on pressure	6	. Repair or replace.
	s w i t c h )	7	. Replace valve assembly.
7	. Compressor valves failed

Knocks, rattles, and/or	1	. Loose mounting bolts	1	. Tighten bolts.
excessive vibration	2	. Tank not level	2. Use sturdy wedge/object to bring tank to level position.
	3	. Cylinder or piston is worn/scored	3	. Replace or repair as necessary.
Tank pressure drops	1	. Loose drain valve	1	. T i g h t e n .
when compressor shuts	2	. Check valve leaking	2	. Remove check valve. Clean or replace.
o f f	3	. Loose connections at fittings, tubing,	3	. Check all connections with soap and water solution.
		e t c .		If a leak is detected, (1) tighten or (2) remove fitting
				and apply pipe tape to threads and reassemble.
	4	. Tank leaks	4	. Check tank for leaks with soap and water solution. If
				leak is detected, tank must be replaced with genuine
				replacement part.

Compressor runs continuously and air output is lower than normal/low discharge p r e s s u r e

1 . Excessive air usage, compressor too s m a l l

2. Clogged intake filter

3 . Loose connections at fittings, tubing, e t c .

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.
