OEM Carrier Pressure Switch with Bracket (HK06WC090) for Model GB1AAV060155ACJA

This is the factory OEM replacement pressure switch with mounting bracket for the Carrier GB1AAV060155ACJA gas furnace. The pressure switch monitors negative pressure created by the inducer draft motor to confirm safe venting conditions before allowing ignition. When this switch fails or sticks open, the control board cannot verify proper draft, causing the furnace to lock out before ever attempting to light — leaving you with no heat. Common symptoms include a furnace that runs the inducer motor but never advances to ignition, or a fault code indicating a pressure switch error.

• OEM vs Generic: This is a genuine Carrier OEM switch calibrated to the exact W.C. rating required by your furnace. Aftermarket pressure switches frequently carry incorrect trip points, causing nuisance lockouts or — more dangerously — allowing ignition under unsafe draft conditions.

Tools needed: flathead screwdriver, needle-nose pliers, and a manometer to verify W.C. reading if diagnosing before replacement. Always disconnect power at the breaker before servicing.
