The pressure switch is a critical safety component in the inducer circuit — it proves that the draft inducer motor has established proper negative pressure before the gas valve is allowed to open. When this switch fails or sticks, the control board will not advance through the ignition sequence, resulting in a no-heat lockout, a blinking fault code, or a furnace that attempts to ignite and then shuts down immediately. Common failure symptoms include the system cycling off on pressure switch fault codes, the inducer running continuously without ignition, or the unit failing to start on a call for heat entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Close pressure: 22\" W.C. | Open pressure: 7\" W.C. | Lead length: 50\" | OEM part number: HK02ZB038 | Factory-calibrated setpoints\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM switch with factory-matched W.C. setpoints.
