The pressure switch is a critical safety device that monitors the negative pressure (vacuum) produced by the draft inducer motor. If the inducer fails to generate adequate airflow, the pressure switch remains open — preventing gas valve energization and protecting the heat exchanger from dangerous flue gas spillage. When this switch fails or sticks, the furnace will lock out on a pressure fault, typically flashing a fault code for a failed or open pressure switch, and the unit will not produce heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e Primary — \u003cstrong\u003eHK02LB008\u003c\/strong\u003e (Gas Pressure Switch, 6.5\" WC cut-out); Cross-reference — \u003cstrong\u003eHK06WC091\u003c\/strong\u003e (SPST Pressure Switch, High Fire).

Aftermarket pressure switches frequently carry ±15% set-point variance, which can cause nuisance lockouts or — more dangerously — fail to protect the heat exchanger under marginal draft conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Disconnect power before servicing.
