The fault triggers compressor and fan shutdown, then VFD reset. If demand is still present the system will attempt to restart normally and run. An intermittent open connection on fan FG wire or a failing fan motor may create these faults.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n<p
