What to do if the suction pressure is abnormally low in my York YST Chiller?
- PPaula DixonJul 25, 2025
Low suction pressure in a York Chiller can stem from a few issues. First, check for refrigerant leaks and charge the system if the refrigerant level is insufficient. A subcooler level valve problem could also be the cause; remove any obstructions. Additionally, inspect the evaporator tubes for dirt or restrictions and clean them if necessary. Finally, if the system load is insufficient for its capacity, check the prerotation vane and hot gas valve operation, as well as the setting of the low liquid temperature cutout.
