What to do if the Ingersoll-Rand Controller ALARM light is on?
- GGeorge SmithAug 4, 2025
If the Ingersoll-Rand Controller's ALARM light is on, first check the status of each compressor using the COMPRESSOR STATUS button to identify any compressor showing “#n COMM FAILURE” or “#n ALARM”. If a compressor shows “#n COMM FAILURE”, refer to the communication problem troubleshooting steps. If it shows “#n ALARM”, go to that compressor and resolve its alarm. Also, refer to the “SENSOR FAILURE” troubleshooting steps.
