How to troubleshoot a Kaishan KRSD Air Compressor that fails to start?
- T
  Taylor MooreAug 19, 2025
  If your Kaishan Air Compressor fails to start, begin by checking the power supply to the unit. If the power supply is working, examine the voltage and power source. If the voltage is low, contact your local power company. Also, inspect the fuse and replace it if blown. Check the start switch for any malfunctions or loose connections. Ensure the emergency button is reset. Examine the motor starter wiring before removing the motor, and have the motor tested at a motor manufacturer repair center if the motor starter overload has tripped. Check all wiring terminals for contact and tightness. If none of these steps resolve the issue, there may be an air-end failure, and you should contact a local authorized distributor.

What to do if Kaishan KRSD shuts down when loaded?
- M
  Michael DeckerAug 21, 2025
  If your Kaishan Air Compressor shuts down during loaded condition, consider these possible solutions: * Address high ambient temperature by making fresh air intake openings or installing ducts to discharge the hot air. * Check for low incoming voltage and, if necessary, contact your local power company. * Reset the unit if the operating pressure is too high, check the line pressure, and ensure it does not exceed the compressor’s maximum. * Top-up fluid if the fluid level is low. * Replace the separator element if the PLC controller indicates that the separator requires maintenance.

Why does the Kaishan KRSD Air Compressor have a high air discharge temperature?
- N
  Nicole Martinez MDAug 23, 2025
  Several factors can cause a high air discharge temperature in your Kaishan Air Compressor. Begin by checking the oil level. If the level is low, add oil. Ensure you are using the correct fluid brand by checking the oil code number and replacing it if necessary. High ambient temperature can also be a factor, so check the air exhaust and try to reduce the room temperature. Inspect the oil filter and change it if it's plugged. If the internal aftercooler is plugged, use chemical cleaning. For dusty after-cooler fins, use a chemical wash. Adjust the fan motor setting. Check and replace the temperature sensor if necessary, and ensure all wires are tightened.

What causes low air capacity delivery in a Kaishan KRSD and how to fix it?
- A
  Amanda TranAug 26, 2025
  If your Kaishan Air Compressor has low air capacity delivery, consider these possible causes: * A plugged air filter: Clean or replace it with a new element. * Air intake valve failure: Remove the intake hose and check the inlet valve for proper operation. * Separator failure: Replace the separator element. * Faulty indirect proportional valve, solenoid, or safety valve: Adjust, repair, or replace as necessary.

What to do if the Kaishan KRSD line pressure rises too high?
- D
  Debbie RandallAug 28, 2025
  If the line pressure of your Kaishan Air Compressor rises above the unload pressure set-point, check for control system air leakage. Replace the air filter element if it is plugged. Remove the intake hose and check the inlet valve for proper operation if the air intake valve is stuck open. Also, check the receiver tank to ensure that it is exhausting air to the atmosphere when the solenoid opens. Repair or replace the blow-down valve if necessary.

Why Kaishan KRSD Air Compressor does not reload when service line pressure drops?
- S
  Sarah PeckAug 30, 2025
  If your Kaishan Air Compressor does not reload when the service line pressure drops to reset, the following could be the reasons: * A faulty solenoid: Repair or replace it as necessary. * Loose wiring connection: Check and tighten wiring terminals. * Faulty proportional valve: Clean or replace the orifice as necessary. * Jammed air inlet valve assembly: Check and repair the air inlet valve. * Faulty air pressure sensor: Repair or replace it as necessary.

How to troubleshoot excessive oil carryover in Kaishan Air Compressor?
- A
  Andrew MartinSep 1, 2025
  To troubleshoot excessive oil carryover in the discharge compressed air of your Kaishan Air Compressor, check the oil level. If it is too high, adjust it. If the oil orifice valve is plugged, clean or replace it. Adjust the discharge pressure if it is too low. Clean or replace the air/oil separator element if it has failed. Check the minimum pressure valve for leaks and replace it if necessary.

What causes Loading Function Failure in Kaishan KRSD Air Compressor?
- T
  Todd BatesSep 3, 2025
  If your Kaishan Air Compressor experiences a loading function failure, check the solenoid valve, proportional valve and minimum pressure valve for failure and replace as necessary. Inspect for any pipe leaks and replace if needed. Remove the intake hose and check the inlet valve for proper operation if the air intake valve is stuck open.

What causes short periods of load/unload in Kaishan KRSD Air Compressor?
- J
  John WareSep 6, 2025
  If your Kaishan Air Compressor experiences short periods of load/unload, check for pipe leaks and replace as necessary. If the pressure setting is too low, change the setting above 1 Bar. If the receiver tank is too small, check or increase the volume of the receiver tank. If the air flow into the main network is restricted, increase the pipe size and check for filter cartridge failure.

Why does the Kaishan Air Compressor fail to unload at working pressure?
- T
  Timothy AlvarezSep 8, 2025
  If your Kaishan Air Compressor fails to unload at working pressure, causing the safety valve to release pressure, adjust the pressure loading setting as necessary. Check the solenoid valve and replace if necessary. Check the air/oil separator and replace if it is plugged. Remove the intake hose and check the inlet valve for proper operation if the air intake valve is stuck open. Repair or replace the safety valve if it has failed. Check and replace the PLC controller if necessary.
