Problem | Probable Cause | Correction | ||
Unit will not run | Tank pressure exceeds “cut in” pressure | Once pressure drops below “cut in” pressure, the unit will start. | ||
| Extension cord causing excessive amp draw | Check guidelines for proper cord gauge | ||
|
| (use of extension cords is not recommended). | ||
| Fuse or circuit tripped | Replace fuse or reset breaker | ||

Air leaks at fittings | Fittings loose | Tighten fitting. Check with soapy water. DO NOT OVER TIGHTEN. | ||
Air leak at pressure switch | Clogged check valve | Remove and clean check valve | ||
Unit will not build pressure | Application requires excessive air demand | Reduce demand on compressor | ||
| Loose head | Tighten bolts on head | ||
| Blown gasket | Remove head and check for | ||
|
| broken or deformed gasket. Replace if needed. | ||
| Open drain cock | Close drain cock | ||
