OEM Carrier Pressure Switch with Bracket for Model GB3AAV060115ACJA — Part# HK06WC090

This is the OEM factory-specified pressure switch with bracket for the Carrier GB3AAV060115ACJA gas furnace. The pressure switch is a critical safety component that monitors negative pressure created by the inducer draft motor to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or its sensing hose becomes cracked or clogged, the furnace control board detects an open circuit and locks out the system — typically resulting in a no-heat condition with a blinking fault code indicating a pressure switch error. Common symptoms include the inducer motor running continuously with no ignition attempt, or the furnace cycling repeatedly without ever reaching the heating stage.

• Specs: Includes factory-matched bracket for direct OEM mounting | Water column (W.C.) rating factory-calibrated for the GB3AAV060115ACJA inducer assembly | Single-port or dual-port configuration per original design | 1/4" spade terminals for plug-and-play reconnection
• OEM vs Generic: This OEM unit carries the exact W.C. rating engineered for this furnace. Aftermarket switches frequently ship with incorrect trip points, causing nuisance lockouts or — worse — failing to detect a true venting fault, which is a serious safety risk.
• Install difficulty: 2/5 — Power down the furnace and allow the inducer to cool before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, needle-nose pliers. Inspect the rubber sensing hose for cracks or blockages before installing the new switch, as a damaged hose is a common root cause of switch failure.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Orders received before cutoff ship same business day from our warehouse.
