If your York Chiller displays a 'System Fault: DISCHARGE PRESSURE LIMITING', it could be due to a defective discharge transducer. Check the transducer against a gauge to verify its accuracy.
What to do if York Chiller has VSD Fault: High Baseplate Temperature?
If your York Chiller shows a 'VSD Fault: High Baseplate Temperature', it could be due to a low coolant level, so add coolant. Another possible cause is a defective glycol pump, which would require replacement.
What to do if York YCAV0357E Chiller displays VSD Fault: Low DC Bus Voltage?
If your York Chiller is showing a 'VSD Fault: Low DC Bus Voltage', it could be due to a defective SCR / Diode Module, so check the SCR / Diode Module.
