- M
  Michael ColemanAug 13, 2025
  If your Ingersoll-Rand Air Compressor fails to start, there are several potential causes: * A loss of 110/120V control voltage: Check the fuses, transformer, and wiring connections. * A starter fault: Inspect the contactors. * Emergency stop engaged: Rotate the emergency stop button to disengage it, and then press the reset button twice. * Main or fan motor overload: Manually reset the main or fan motor overload relay, and then press the reset button twice. * Sensor failure: Check for defective sensors, bad sensor connections, or broken sensor wires. * Intellisys 24 VAC control voltage not available: Check fuses. * Display panel and power on light does not illuminate: Check wiring and verify that the 24 VAC is within the voltage tolerance (± 15%).

  Christopher HesterAug 17, 2025
  If you're experiencing low system air pressure with your Ingersoll-Rand Air Compressor, here's what you can check: 1. Ensure the compressor isn't running in UNLOAD mode by pressing the LOAD button. 2. Verify the controller off-line set point isn't too low; press the STOP button and set it to a higher value. 3. Inspect the air filter element for dirt and replace it if needed. 4. Check the air system piping for leaks. 5. Inspect and repair the moisture separator trap drain if it's stuck open. 6. Ensure the inlet valve is fully open by inspecting and repairing it, and check the control system operation. 7. Consider if the system demand exceeds the compressor's delivery capacity, and install a larger or additional compressor if necessary.

Why is my Ingersoll-Rand Air Compressor using too much coolant?
- T
  Traci DavisAug 25, 2025
  If your Ingersoll-Rand Air Compressor is experiencing high coolant consumption or coolant in the air system, consider the following: * Excessive coolant level or plugged separator element: Check the coolant level and lower it if necessary by draining. Check the separator pressure drop. * Separator element leak: Check the separator pressure drop and replace the element if it is low. * Plugged separator scavenge screen/orifice: Remove and inspect the screen/orifice, and clean it if required. * Compressor operating at low pressure (75 psig [5.2 bar] or below): Operate the compressor at rated pressure and reduce system load. * Coolant system leak: Inspect and repair any leaks.
