OEM Carrier Pressure Switch for PG92SAS42060BAAA Gas Furnace

The pressure switch is a safety device that confirms the draft inducer motor is actually moving combustion air before the control board allows the igniter and gas valve to fire. It senses the negative pressure created by the inducer through a small rubber hose. If proper draft isn't proven, ignition is blocked. When the switch fails or its hose clogs, the furnace runs the inducer but never lights — you'll see a pressure-switch fault code, hear the inducer cycle on and off, and get no heat, often with the unit locking out after several failed attempts. This is a normally-open negative-pressure switch calibrated to a specific trip point (measured in inches of water column, typically around -0.40 to -0.85 in. w.c. for this furnace stage). It closes when the inducer pulls the rated vacuum and opens the moment draft is lost — protecting against blocked flue or condensate-drain backup. Why OEM matters here: the trip-point setpoint is everything on a pressure switch. A generic switch with the wrong w.c. rating will either nuisance-trip and cause no-heat lockouts, or close too easily and defeat the safety it exists to provide — risking ignition without adequate venting. The OEM switch matches the exact setpoint, port size, and bracket for the PG92. Install difficulty: 2 of 5. Tools: 1/4" nut driver and a multimeter to check continuity across the terminals. SAFETY: turn off power at the furnace breaker before servicing, and inspect the hose and inducer port for condensate or debris — a clogged hose mimics a bad switch.
