What to do if Ingersoll-Rand Air Compressor will not start?
- M
  Melissa ShafferAug 20, 2025
  If your Ingersoll-Rand Air Compressor won't start, first check if the power supply is switched on. If the power is on, then the controller might have failed, so check the supply to the controller and replace it if necessary. Alternatively, there could be a starter failure; in this case, isolate the supply, lock it off, tag it, and replace the failed component. If you are not sure how to do it, contact a qualified electrician or your local Ingersoll Rand representative.

What to do if Ingersoll-Rand RS11i is stopped and will not restart?
- J
  jameslesterAug 22, 2025
  If your Ingersoll-Rand Air Compressor is stopped and will not restart, it could be because the controller has tripped and hasn't been reset. Also, check if the emergency stop button has been pressed and not released; if so, identify the reason, repair the fault, disengage the button, and reset the controller. Another possibility is that the emergency stop button was pressed and released, but the controller hasn't been reset, so repair the fault and reset the controller. For more information, consult Tables 4 and 6.

What to do if my Ingersoll-Rand Air Compressor package draws too much current?
- F
  fharrellAug 28, 2025
  If your Ingersoll-Rand Air Compressor package is drawing too much current, it could be due to several reasons. First, check if the compressor is operating above the rated pressure and modify the settings accordingly. It's also possible that the separator filter element is dirty or blocked, in which case you should replace it. If the voltage supply is low or unbalanced, contact a qualified electrician or your local Ingersoll Rand representative. Finally, the airend might be damaged, which also requires contacting your local Ingersoll Rand representative.

Why is there high airend discharge temperature in my Ingersoll-Rand RS11i Air Compressor?
- W
  Wanda HarrisAug 30, 2025
  A high airend discharge temperature in your Ingersoll-Rand Air Compressor can be caused by several factors. The compressor might be operating above its rated pressure, so check and adjust the settings. Low coolant level can also cause this, so check for leaks and top up the coolant. High ambient temperatures or insufficient cooling air can also contribute, so review the installation and system parameters and check the ducting and cooling air path. Lastly, a dirty or blocked coolant cooler can cause this issue, so clean or replace it. For further assistance, contact your local Ingersoll Rand representative.

How to fix black residue on belt guard or airend of Ingersoll-Rand RS11i Air Compressor?
- I
  Ian ReedAug 31, 2025
  If you notice black residue on the belt guard or airend of your Ingersoll-Rand Air Compressor, it could be due to drive belt slippage, in which case you should replace the belt and gas spring. Another possibility is that the pulley is misaligned, so re-align it. Also, check for worn pulleys and replace the pulley and belt if necessary. If the gas spring has failed, replace it.

What to do if discharge air is contaminated with coolant in Ingersoll-Rand RS11i?
- N
  Nicole MooreSep 3, 2025
  If the discharge air from your Ingersoll-Rand Air Compressor is contaminated with coolant, it could be due to several reasons. The scavenge pipe might be blocked, broken, or the o-ring isn't sealing, so clean or replace it. The separator element might be punctured, incorrect, require changing, or not sealing correctly, so replace it. If incorrect coolant has been added, drain the system, check for damage, clean it, and refill it with the correct coolant. If the system has been overfilled with coolant, check for damage and drain the excess.

What causes high dewpoint in Ingersoll-Rand RS11i Air Compressor?
- S
  sroachSep 4, 2025
  A high dewpoint in your Ingersoll-Rand Air Compressor can be caused by several factors. Check if the refrigeration compressor is supplied with power and inspect the dryer protection fuse. Also, check the auxiliary contact on the main motor contactor and the operation of the drain valve and condensate check valves. A dirty condenser can also cause this issue, so clean the condenser and replace the panel filter element.

What to do if discharge air is contaminated with condensate in Ingersoll-Rand RS11i?
- W
  Whitney WeaverSep 8, 2025
  If the discharge air from your Ingersoll-Rand Air Compressor is contaminated with condensate, it could be due to the aftercooler not functioning correctly, so clean or replace it. Another possibility is a faulty moisture separator drain trap, which should be repaired or replaced. Continuous low speed or low ambient operation can also cause condensate buildup; in this case, review the system requirements and contact your local Ingersoll Rand representative.
