The pressure switch is a critical safety device that monitors inducer assembly operation by sensing negative air pressure (draft) before allowing the ignition sequence to proceed. When the switch fails or becomes stuck open, the control board cannot confirm safe venting conditions — resulting in a lockout, no-heat call, or a furnace that attempts ignition but shuts down before the burners fire. A faulty pressure switch is one of the most common causes of furnace no-heat service calls.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Opens at 7\" W.C. | Closes at 22\" W.C. | 50\" wire leads | 24V control circuit | OEM part# HK02ZB044 | Country of origin: Mexico\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch, manufactured to exact factory pressure tolerances.
