If the rod is dirty, cracked, or weak, the board cuts gas as a safety response — producing short-cycling, intermittent no-heat, and repeated lockouts. Replacing this sensor is the fastest fix for a furnace that lights then drops out after a few seconds. This direct-fit rod is built to exact Carrier specifications for the LC348TM402289, ensuring correct length, mounting position, and signal strength for reliable flame proving. Installation is one of the simplest furnace repairs — about 15 minutes: turn off power, remove a single screw, disconnect the lead, and install the new sensor. No tools beyond a nut driver and no recalibration needed. Most homeowners manage it easily; technicians treat it as routine maintenance. Genuine OEM quality means dependable operation all season.
