Symptom

 

Possible Cause(s)

Corrective Action

 

 

 

 

Compressor will not run

1.

Loss of power or overheating

1. Check for proper use of extension cord (see EXTENSION

 

 

 

 

 

CORDS, page 3)

 

 

 

 

 

2.

No electrical power

2. Plugged in? Check fuse/breaker

 

 

 

3.

Blown fuse

3. Replace blown fuse

 

 

 

4. Breaker open

4. Reset. Determine why problem happened

 

 

 

5.

Thermal overload open

5. Motor will restart when cool

 

 

 

6.

Pressure switch bad

6. Replace

 

 

 

 

 

 

 

 

 

 

Motor hums but cannot

1. Low voltage

1. Check with voltmeter

 

 

run or runs slowly

2.

Wrong gauge wire or length of

2. Check gauge chart under Operation for proper gauge

 

 

 

 

extension cord

wire and cord length

 

 

 

3. Shorted or open motor winding

3. Replace motor

 

 

 

 

 

4.

Defective check valve or unloader

4. Replace or repair

 

 

 

 

 

5.

Unit is cold, oil too thick

5. Use 5W-30 synthetic (Mobil 1) and/or warm up the unit

 

 

 

6.

Low oil level

6. Add oil to full line on dipstick

 

 

 

7.

Defective capacitor

7. Replace or repair

 

 

 

 

 

 

 

 

 

 

Fuses blow/circuit

1.

Incorrect size fuse, circuit overloaded

1. Check for proper fuse, use time-delay fuse. Disconnect

 

 

breaker trips repeatedly

 

 

other electrical appliances from circuit or operate

 

 

 

 

 

compressor on dedicated branch circuit

 

 

 

2.

Wrong gauge wire or length of

2. Check gauge chart, under Operation

 

 

 

 

extension cord

 

 

 

 

 

 

 

3.

Defective check valve or unloader

3. Replace or repair

 

 

 

 

 

4.

Low oil level

4. Add oil to full line on dipstick

 

 

 

 

 

 

 

 

 

Thermal overload

1.

Low voltage

1. Check with voltmeter

 

 

protector cuts out

2.

Clogged air filter

2. Clean filter (see Maintenance section)

 

 

repeatedly

3.

Lack of proper ventilation/room

3. Move compressor to well ventilated area

 

 

 

 

temperature too high

 

 

 

 

 

 

 

4.

Wrong gauge wire or length of

4. Check gauge chart, under Operation

 

 

 

 

extension cord

 

 

 

 

 

 

 

5.

Low oil level

5. Add oil to full line on dipstick

 

 

 

 

 

 

 

 

 

Tank pressure drops

1.

Loose connections (fittings, tubing, etc.)

1. Check all connections with soap and water solution and

 

 

when compressor shuts

2.

Loose drain lock

tighten

 

 

 

 

off

3.

Check valve leaking

2. Tighten

 

 

 

 

 

 

 

3. Disassemble check valve assembly, clean or replace

 

 

 

 

 

 

 

Do not disassemble check valve

 

 

 

 

 

! DANGER

 

 

 

 

 

 

 

with air in tank; bleed tank

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Excessive moisture in

1.

Excessive water in air receiver

1. Drain receiver

 

 

 

 

discharge air

2.

High humidity

2. Move to area of less humidity; use air line filter

 

 

 

 

 

 

 

 

 

 

Compressor runs

1.

Defective pressure switch

1. Replace switch

 

 

 

 

continuously

2.

Excessive air usage

2. Decrease air usage; compressor not large enough for air

 

 

 

 

 

requirement

 

 

 

 

 

3.

Air leak

3. Repair or replace leaking component

 

 

 

 

 

 

 

 

Compressor vibrates

Loose mounting bolts

Tighten pump mounting bolts so rubber washer is

 

 

 

 

 

slightly compressed

 

 

 

 

 

 

 

 

 

Compressor “walks” on

Foot mounting bolts not securely

Tighten foot mounting bolts underneath tank assembly

 

 

hard surfaces

tightened

 

 

 

 

 

 

 

 

 

 

 

 

Air output lower than

1.

Broken valves

1. Have authorized service representative repair unit

 

 

normal

2.

Intake filter dirty

2. Clean or replace intake filter

 

 

 

3.

Connections leaking

3. Tighten connections
