OEM Carrier Pressure Switch with Bracket HK06WC090 for Model PG8UAA024045ADJA

This is the genuine OEM factory-specified pressure switch with mounting bracket for the Carrier PG8UAA024045ADJA packaged gas furnace. The pressure switch monitors negative air pressure created by the inducer motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or sticks open, the furnace control board will lock out the heating cycle entirely — typically resulting in a no-heat call with the inducer running continuously but no ignition attempt ever starting.

• OEM vs Generic: This is a genuine Carrier OEM part manufactured to exact factory tolerances. Generic pressure switches can carry setpoint variance that causes nuisance lockouts or, worse, unsafe operation — OEM is always the recommended choice for pressure-sensing safety components.
