Why is there no display on my Johnson Controls York YCIV A control panel and the unit won't run?
- MMary JohnsonJul 31, 2025
If there is no display on the control panel and the Johnson Controls Chiller unit won't run, it could be due to several reasons. It's possible that the supply to the panel is missing; in this case, check fuses 1FU, 2FU, 4FU, 5FU, 17FU, or 19FU. Alternatively, a line fuse may have blown, so check the fuses. It could also be that the Chiller Control Board or the Display Board are defective, requiring replacement.
