Carrier HK06NB017 Pressure Switch 320720-756 preventing leakage even in systemsThe Carrier HK06NB017 is a critical OEM dual pressure switch assembly designed specifically for two stage high efficiency condensing furnaces. This Honeywell manufactured component features two distinct calibrated setpoints: a low pressure circuit at 0. 71" wc and a high pressure range of 1. 60" 1. 81" wc. This configuration allows the furnace control board to verify proper venting and inducer motor performance across both low and high fire heating
