The pressure switch is a critical safety component that monitors the inducer blower's negative pressure to confirm proper draft before allowing the ignition sequence to proceed. When this switch fails — whether due to a ruptured diaphragm, blocked port, or faulty electrical contact — the furnace or packaged unit will enter a safety lockout, typically displaying a fault code and refusing to advance past the inducer stage. Replacing with the correct OEM part ensures your W.C. (water column) rating is factory-matched and your system resumes normal operation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number HK06WC061 | Factory-calibrated W.C.
