It is a key safety control that confirms the draft inducer is properly venting combustion gases before the furnace is allowed to ignite. When it senses the correct negative pressure it closes and permits the sequence to continue; if venting is restricted or the inducer is weak, it stays open and halts ignition to keep operation safe. A stuck or failed pressure switch is a common cause of ignition lockouts and pressure-switch error codes. The genuine Carrier switch carries the exact inches-of-water-column trip setting your furnace requires—precisely what universal switches tend to get wrong. Installation is easy, roughly 15–20 minutes: turn off power, remove the rubber hose, take out the mounting screws, transfer the wires, and reinstall. No calibration needed. Genuine OEM parts help preserve your warranty and ensure safe, consistent cycling. In stock right now—order before 3PM CST for same-day shipping.
