It opens at 135°F and automatically closes at 95°F to resume normal operation without requiring a technician to push a reset button

and premature blower motor wear due to turbulence

We recommend checking for low-voltage shorts before replacing the transformer to prevent repeat failure

A PRS code typically signifies insufficient water flow through the heat exchanger

This prevents desiccant attrition and ensures that even the smallest contaminants are trapped before they can reach the expansion valve

Heil Quaker ICP 1175517 TXV Kit 318423-701 It opens at 135°F andThe Heil Quaker ICP 1175517 TXV Kit is a critical OEM replacement component designed for precision refrigerant metering in units utilizing R 22 refrigerant. As a thermostatic expansion valve specialized for 3 ton to 5 ton applications, this kit maintains optimal evaporator superheat by modulating the flow of liquid refrigerant based on load demand. This ensures maximum heat transfer efficiency and prevents liquid slugging, which can lead to premature
