What causes a Ingersoll-Rand Sierra H 400 to fail to load?
- W
  wbennettAug 26, 2025
  If your Ingersoll-Rand Air Compressor fails to load, start by checking for leaking seals in the hydraulic cylinder. If the cylinder doesn't fully stroke when the 'Load' button is pressed, overhaul the hydraulic cylinder. Also, check for a defective load solenoid valve by removing the tube that runs from the load solenoid valve to the hydraulic cylinder. Start the compressor and press the 'Load' button; if oil doesn't come out of the solenoid valve, replace it.

How to get rid of water in Ingersoll-Rand Sierra H 400 system?

  If you find water in your Ingersoll-Rand Air Compressor system, start by inspecting the moisture separator/drain trap for defects and clean if required; replace if defective. Check the trap drain and drain piping for any blockages and clean them. Inspect and clean the aftercooler core if it's dirty. Ensure all enclosure panels are in place. If the unit lacks an aftercooler, consider installing one. Finally, ensure the drain line/drip leg is correctly installed, sloping the drain line away from the trap and installing a drip leg.

Why does the pressure relief valve keep opening on my Ingersoll-Rand Air Compressor?
- E
  Elizabeth HudsonSep 9, 2025
  If the pressure relief valve on your Ingersoll-Rand Air Compressor opens, it could be due to the compressor operating over pressure; adjust the controller set points. Alternatively, the valve itself may be defective and require replacement.
