Why is the discharge pressure abnormally high in my York MaxE YK Chiller?
- W
  Wendy TaylorAug 16, 2025
  High discharge pressure in your York Chiller can occur due to several reasons: * Air might be present in the condenser. * The condenser tubes could be dirty or scaled, requiring cleaning and a check of water conditioning. * The condenser water temperature may be too high, necessitating a reduction in the condenser water inlet temperature, along with checks of the cooling tower and water circulation. * There may be insufficient condensing water flow; in this case, increase the quantity of water flowing through the condenser to the appropriate level.

  Amanda ContrerasAug 18, 2025
  Low suction pressure in your York Chiller may be due to: * Insufficient refrigerant charge. Check for leaks and add refrigerant to the system. * A variable orifice problem. Remove any obstruction. * Dirty or restricted evaporator tubes. Clean the evaporator tubes. * Insufficient load for the system capacity. Check the prerotation vane motor operation and setting of the low water temperature cutout.

  If your York Chiller's oil pressure system stops returning an oil/refrigerant sample, it might be because: * The filter-drier in the oil return system is dirty. Replace the old filter-drier with a new one. * The jet or orifice of the oil return jet is clogged. Remove the jet, inspect it for dirt, remove the dirt using a solvent, and then replace the jet.
