The pressure switch proves that the draft inducer is operating correctly before allowing the gas valve to open — it is a critical safety interlock in your furnace's sequence of operation. When this switch fails or sticks open, the control board cannot confirm inducer operation and will lock out the furnace, typically before any ignition attempt. Common symptoms include a blinking fault code indicating a pressure switch fault, the inducer running but no ignition occurring, or a no-heat call that resets itself after a power cycle only to fail again.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e HK02LB008 (Gas Pressure Switch) | HK06WC091 (Pressure Switch) — both superseded numbers covered by this listing.

(water column) tolerances. Generic aftermarket switches frequently drift from their rated set point, causing nuisance lockouts or — more dangerously — failing to open when the inducer is actually under-performing. For a safety-critical component like this, OEM specification is strongly recommended.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Shut off power and gas supply before beginning.
