Liebert Deluxe 3 display panel issue
I have a water cooled air handler with the old style of display. Nothing lights up on the display except the SET light which doesn't turn off. The unit runs but we had to disassemble the chill water valve to get it to cool. Both boards were changed and so was the panel. Could the unit be stuck in test mode?
