The pressure switch is a critical safety and sequencing component: it monitors inducer motor draft pressure to confirm proper venting before allowing the ignition sequence to proceed. When this switch fails or becomes stuck open, the furnace will enter a pre-ignition lockout — the inducer will run but the igniter will never energize, leaving you with no heat. A faulty pressure switch is one of the most common causes of a furnace that starts the inducer but never moves into the heating cycle.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 7 PSI | Closes at 22 PSI | 24V control circuit | 50\" wire leads | Country of Origin: Mexico | OEM Part Number: HK02ZB044\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the factory-original Carrier component, engineered to exact design-life specifications.
