Symptom |
Cause |
Solution |
Compressor will not start. |
Power cord not plugged in or plugged into a bad outlet. |
Check power cord, try a different outlet. |
Machine in high pressure shut off. |
See symptom below. |
|
Motor in thermal overload. |
Allow motor to cool down. |
Compressor tries to start but just makes a buzzing sound. |
Low voltage caused by poor source power, small gauge ex-tension cord or too long of an extension cord. |
Locate better outlet, reduce length of extension cord and use a heavy gauge cord. |
|
Too much back pressure on compressor. |
Close the input valve to relieve any back pressure on compressor. |
Machine pumps into high pressure shut off. |
Valve on machine or tank closed. |
Check to see if valves are opened and are not plugged. |
|
Restriction in output hose. |
Check hose for blockage and remove any core depressors. |
|
|
Relieve pressure from output hose to reset switch. |
Pumps liquid slowly. |
Restriction in flow. |
Use proper size hoses and if possible remove any core depressors and Schraeder valves. |
|
Trapped liquid in system. |
Cycle system compressor for a few seconds to move trapped liquid to another area. |
