The pressure switch is a safety device that monitors negative pressure created by the inducer motor to confirm proper venting before allowing ignition to proceed. When this switch fails or the diaphragm cracks, the furnace will lock out before ever reaching the ignition stage — leaving you with no heat and a flashing fault code indicating a pressure switch fault. Common symptoms include the inducer motor running continuously with no ignition attempt, or the furnace cycling off immediately after startup.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM-rated water column (W.C.) pressure setting factory-matched to GB3AAV060135ABJA | Includes mounting bracket | Single-port design | 24V control circuit compatible | Direct drop-in replacement for part number \u003cstrong\u003eHK06WC090\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM pressure switches are calibrated to exact W.C. specifications for your furnace's inducer and venting configuration.
