Reasons Ingersoll Rand Compressor Shows Fault Codes

In the event of a system fault of some sort the Ingersoll Rand compressor should display a fault code in the user operational display menu on the controller. If there is more than one fault code active, each will be displayed as separate items in this operational display menu; they can be viewed by pressing up or down to view.

Ingersoll Rand Fault Codes

The fault codes displayed on the Ingersoll Rand air compressor will typically be separated into:

  • Unit faults (ERR/ERROR)
  • System alarms (SYS/WARNING)

Error Fault

When the compressor displays an error or shutdown, the conditions of the error will automatically reset once the condition has been resolved, and the air compressor has restarted and works with no issues.

System Fault

When the compressor displays a system alarm warning, the conditions are automatically reset when the condition has been resolved and reset on the compressor.

It’s common for the fault codes to be separated by some regarding a problem or error with the controller itself which prevents normal operation of the compressor, and system faults that occur externally from the controller and with the compressor.

The Ingersoll Rand compressor fault codes will likely show their errors in two different light patterns:

  1. LED flashing slowly – this indicates an alarm warning condition where the compressor is continuing with the normal operation but user attention is required still.
  2. LED flashing fast – this indicates a trip condition where the controller will stop the operation of the compressor until the conditions of the error are resolved.

In most cases, the fault codes should be labeled with unique numeric codes which can then be understood from the user’s manual for the specific Ingersoll Rand compressor.

Ingersoll Rand Compressor Fault Codes


After servicing the compressor it would have a trouble code that will show up and say service.

Is there a reset that you have to do to the computer to clear this out of the system so it knows you serviced it, and if so how do you clear it?

Thank you.

Ingersoll Rand compressor having main motor lock alarm and how to find out the solution.

What are you talking about? IR makes many different sizes and types of compressors.
If you can’t find a model, perhaps we could venture a guess based on a pic of the motor and nearby components.

I might be able to tell if I knew what compressor you have…more than just IR…

My Ingersoll Rand dryer model R5.5IU-SD started showing error message PF 1 and later changed to E 52. Now it stopped working

Is this a R5.5IU-10-200SD-D with the dryer D72IN? Just to clarify…
If so, have you tried a power-off reset?
Is the second error not ES2? Is there ice on the cooling radiators?
