The pressure switch monitors negative pressure created by the inducer draft motor to confirm that the heat exchanger flue path is clear before allowing the gas valve to open. When this switch fails or sticks open, the furnace control board interprets it as a blocked flue or inducer fault — resulting in a no-heat lockout condition that prevents ignition entirely. A faulty pressure switch is one of the most common causes of a furnace that attempts to start, flashes an error code, and shuts down before reaching ignition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e Close setpoint: \u003cstrong\u003e-2.2\" W.C.

Aftermarket pressure switches frequently carry wider tolerance bands, which can cause nuisance trips or, worse, allow ignition under unsafe draft conditions. OEM is always the correct choice for pressure-sensing safety controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — No special tools required.
