OEM Carrier Pressure Switch with Bracket HK06WC090 for Model GB1AAV060155AEJA

This is the factory OEM replacement pressure switch with integrated mounting bracket for the Carrier GB1AAV060155AEJA gas furnace. The pressure switch monitors negative pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or becomes stuck, the control board will not advance past the inducer stage, resulting in a no-heat lockout condition. Common symptoms include the inducer running continuously with no ignition, a flashing fault code indicating a pressure switch error, or intermittent heating that drops out mid-cycle.
