If your Craftsman air compressor isn't building up pressure, it could be due to a few reasons: leaks in the air lines, a worn compressor pump, a faulty valve, or an issue with the pressure switch. Consult the troubleshooting section of the owner's manual for Model 921.15310 for a step-by-step guide on diagnosing and resolving pressure issues.
