Solution
1.Check for proper use of extension cord
2.Plugged in? Check fuse/breaker or motor overload
3.Replace blown fuse
4.Reset, determining why problem happened
5.Motor will restart when cool; turn off compressor and wait 20 minutes
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
Thermal |
| 1. Low voltage |

|
| |
|
| 3. | Check valve | leaking |
| |||
1.Check with voltmeter
2.Clean filter
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
, _,, , Do not disassemble check valve with air in tank;bleed tank
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 a requirement
3.Disassemble check valve assembly, clean or replace
