If it detects a blocked vent, failed inducer, or condensate backup, it prevents ignition to protect against dangerous flue conditions. A faulty or stuck switch commonly causes ignition lockout, pressure-switch flash codes, or a furnace that won't fire. This genuine OEM Carrier pressure switch is built to factory specifications as a direct-fit replacement for the GA1AAD048105ACJA gas furnace, with the correct trip point, port configuration, and electrical terminals. Installation is easy to moderate for a qualified technician — power down, disconnect the hose and wires, mount the new switch, and reconnect. Choosing the OEM switch ensures the precise pressure calibration your safety system depends on, which generic parts often get wrong. Restore safe, reliable ignition with the component engineered for your model. In stock and ready to ship. Orders placed before 3PM CST ship the same business day.
