Ingersoll Rand Intellisys NTLS100-200HP part# 39825716 will not go into auto restart
We have an Ingersoll Rand NTLS100-200HP part# 39825716 Intellisys unit on a Sierra Oil Free Rotary Compressor that will not go into Auto Restart. We have changed out all sensors and circuit boards, the controller itself has been repaired. Any ideas?
