It senses negative pressure from the inducer motor and proves the flue is clear; if it fails or sticks open, the furnace locks out and refuses to fire, often showing a pressure-switch fault code. This direct-fit replacement matches the original trip-point rating (in inches of water column) and hose port configuration, so it installs without recalibration. Replacing a faulty switch resolves intermittent no-heat conditions caused by false safety trips—but always inspect the rubber tubing and condensate trap for blockage first, since a clogged hose mimics a bad switch. Installation is a beginner-friendly job, usually under 20 minutes with a nut driver, after shutting off power. Reconnect the hose firmly and verify the wiring spade terminals are snug. Trust OEM-spec safety components to keep your Carrier furnace running correctly.
