Carrier HK02ZB042 Pressure Switch 328140-751 a different series of dampersThe Carrier HK02ZB042 Pressure Switch is a critical OEM safety component designed for precise monitoring of combustion air and venting pressure within high efficiency Carrier, Bryant, and Payne furnaces. Factory calibrated to 42# Open and 57# Close, this low pressure switch ensures the inducer motor is moving sufficient air to clear combustion byproducts before allowing the ignition sequence to proceed. It features a 36" lead and a durable diaphragm
