breaker trips
repeatedly 2. Wrong gauge wire or length of
extension cord
3. Defective check valve or under loader
Air leaking from Check valve stuck in an open position
unloader on
pressure switch
Motor stalls Defective check valve
Thermal overload 1. Low voltage
protector cuts out 2. Clogged air filter
repeatedly 3. Lack of proper ventilation/room
temperature too high
4. Wrong gauge wire or length of
extension cord
Air receiver 1. Loose connections (fittings, tubing,
pressure drops etc.)
when compressor 2. Loose drain cock
shuts off 3. Check valve leaking
Excessive moisture 1. Excessive water in air receiver
in discharge air 2. High humidity
Compressor runs 1. Defective pressure switch
continuously 2. Excessive air usage

Corrective Action
1. Check for proper use of extension cord (See Extension Cords)
2. Plugged in? Check fuse/breaker or motor overload
3. Replace blown fuse
4. Reset, determine why problem happened
5. Motor will restart when cool
6. Replace
1. Check with voltmeter
2. Check gauge chart, under Operation for proper gauge wire and cord
length
3. Replace motor
4. Replace or repair
1. Check for proper fuse, use time-delay fuse. Disconnect other electrical
appliances from circuit or operate compressor on its own branch circuit
2. Check gauge chart, under Operation
3. Replace or repair
Remove and replace check valve
Remove and replace check valve
1.Check with voltmeter
2. Clean filter (See Maintenance section)
3. Move compressor to well ventilated area
4. Check gauge chart, under Operation
1. Check all connections with soap and water solution and tighten
2. Tighten
3. Disassemble check valve assembly, clean or replace
1. Drain receiver
2. Move to area of less humidity; use air line filter
1. Replace switch
2. Decrease air usage; compressor not large enough for air requirement
Tighten
1. Have authorized service representative repair unit
2. Clean or replace intake filter
3. Tighten connections
