Experiencing issues with your Chicago Pneumatic air compressor? Having a reliable troubleshooting guide is essential to keep your equipment in top condition. In this article, we provide expert advice and practical solutions for common air compressor problems, from low pressure to unusual noises, ensuring your compressor operates efficiently.
Compressor Troubleshooting
Below are some quick tips to help you diagnose and resolve common issues with your air compressor:
- Check the Power Supply: Ensure your air compressor is properly connected to a power source and that the circuit breaker has not tripped.
- Inspect the Air Filter: A clogged air filter can reduce efficiency and cause overheating. Regularly replace the air filter according to the maintenance schedule.
- Monitor the Oil Level: Low oil levels can lead to overheating or even seizure of the compressor. Regularly check and top up the oil as needed.
- Verify Pressure Settings: Incorrect pressure settings can cause the compressor to continously run or fail to start at the desired pressure. Refer to the manual to set the correct pressure for your machine.
- Examine Valves and Hoses: Leaking valves or hoses can lead to pressure loss or operational failure. Inspect for leaks and make necessary repairs. For internal leaks within the compressor, contact your local Chicago Pneumatic dealer.
- Consult the Manual: Always refer to the instruction manual for additional troubleshooting tips and safety instructions.
Troubleshooting Chart
Still encountering issues? The troubleshooting chart below can help resolve common problems associated with air compressors. Always check the manual and follow safety guidelines before working on your equipment. When in doubt, contact Chicago Pneumatic Compressors.
Condensate is not being discharged from the condensate trap(s) during loading
- Discharde pipe of the condensate trap is clogged: Inspect and clear any blockages.
- Float valve of the condensate trap(s) is malfunctioning: Remove, clean, and inspect the float valve assembly. If necessary, contact us for assistance.
Compressor air delivery or pressure is below normal
- Air consumption exceeds compressor's delivery capacity: Verify the air requirements of connected equipment.
- Clogged air filters: Replace the air filters.
- Air leakges: Inspect and repair any leaks.
Compressor element outlet temperature or delivery air temperature is above normal
- Insufficient cooling air:
- Check for restrictions in the cooling air supply
- Enhance ventilation in the compressor room
- Prevent recirculation of cooling air
- Oil level too low: Check and adjust the oil level as needed.
- Oil cooler dirty: Clean the oil cooler to remove dust and ensure the cooling air is free from contaminants.
- Oil cooler clogged: Contact us for assistance.
- On water-cooled units, cooling water temperature too high flow too low: Increase the water flow and monitor the temperature.
- On water-cooled units, restriction in the cooling water system due to dirt or scale formation: Inspect, clean the water circuit and coolers.
Safety valve blows after loading
- Faulty safety valve: Check the pressure setpoint and contact our local service team for assistance.
- Inlet valve maintenance: Seek assistance from your local Chicago Pneumatic dealer.
- Minimum pressure valve malfunctioning: Consult our technical support for troubleshooting.
- Clogged oil separator element: Replace the oil, oil filter, and oil separator element.
- Dryer piping clogged due to ice formation: Inspect the freon circuit for leaks and contact your local Chicago Pneumatic dealer for service.
Compressor fails to start or stops during operation, with Elektronikon showing a motor overload issue
- Motor overload relay (F21) triggered: Reset the overload once. If the problem persists, get in touch with us.
- Circuit breaker (Q15) or fan motor overload (F15) triggered: Reset the overload once. If it continues to occur, contact us.
- Motor thermistor (K34) tripped or faulty: Reset the overload once. If the issue repears, get in touch with us.
- Phase sequence relay (K25) open: Verify and correct the phase sequence at the machine's power inlet if necessary.
- Wiring interruption: Contact us for futher diagnosis
Compressor starts but fails to load after a delay
- Solenoid valve mallfunctioning: Replace the solenoid valve
- Inlet valve stuck in the closed position: Have the inlet valve inspected by your local Chicago Pneumatic dealer.
- Leak in control air tubes: Inspect and replace any leaking tubes.
- Minimum pressure valve leaking (when air network is depressurised): Have the minimum pressure valve inspected by your local Chicago Pneumatic dealer.
Compressor fails to unload, safety valve blows
- Solenoid valve malfunctioning: Replace the solenoid valve
- Inlet valve not closing properly: Have the inlet valve inspected by us
Compressor air output or pressure is below normal
- Air consumption exceeds compressor capacity
- Repair any compressed air leaks
- Increase capacity by adding or upgrading the air compressor
- Clogged air filters: Replace air filters
- Solenoid valve malfunctioning: Replace the solenoid valve
- Clogged oil separator element: Replace the oil, oil filter, and oil separator element
- Air leaks: Repair leaks and replace leaking tubes
- Leaking safety valve: Replace the safety valve
- Inlet valve not fully opening: Have the inlet valve inspected by us
Pressure dewpoint is too high
- Air inlet temperature too high: Check and adjust as needed; consider installing a pre-cooler.
- Ambient temperature too high: Correct the temperature; if necessary, duct cooler air from another location or move the dryer.
- Air inlet pressure too low: Increase the inlet pressure
- Dryer capacity exceeded: Reduce the airflow
- Refrigerant shortage: Have the circuit checked for leaks and recharge it; contact your local Chicago Pneumatic dealer.
- Refrigerant compressor not running: Verify the power supply to the refrigerant compressor
- Condenser pressure too high: Check the fan or fan motor; contact your local Chicago Pneumatic dealer.
- Evaporator pressure too high or too low during unloading: Have the hot gas bypass valve adjusted; contact your local Chicago Pneumatic dealer.
