Common Troubleshooting for Air Compressors
Common Troubleshooting for Air Compressors:
Machine does not start: Check the main switch and power supply cable, inspect the motor.
Machine does not load after starting: Adjust the pressure switch setting or replace the pressure switch, check or replace the solenoid valve.
Compressor does not unload, safety valve releases pressure: Adjust the pressure switch setting or replace the pressure switch, check or replace the solenoid valve.
Excessive oil consumption: Use recommended oil, lower oil level to normal position, remove and clean the oil return pipeline, replace oil separator filter element.
Discharge pressure lower than specified value: Reduce air usage or increase compressor capacity, check for system leaks, clean or replace intake filter element, replace oil separator filter element, check or replace solenoid valve, service intake control valve, replace belts, adjust pressure switch setting.
Compressor stops due to high temperature protection: Improve environmental ventilation conditions, clean or wash the cooler, refill oil to specified level, replace oil filter.
Compressor unloads but discharge pressure still rises slowly, safety valve releases pressure: Check or replace solenoid valve, service intake control valve, service unloading pipeline.
Safety valve releases pressure: Service or replace safety valve, service minimum pressure valve, replace oil separator filter element, service or replace pressure switch, check intake control valve or solenoid valve.
