The switch confirms that exhaust gases are being vented correctly before the burners light; when it fails or sticks, the furnace locks out and refuses to fire, leaving you without heat. This factory-calibrated switch trips at the exact pressure threshold your unit requires, ensuring safe, reliable operation and protecting against dangerous venting conditions. Built to Carrier specifications, it matches the original's port configuration and mounting for a precise fit on the LC350TM400571. Installation is straightforward, typically taking 15-25 minutes with basic hand tools and careful attention to hose routing. Always disconnect power before servicing. Choosing a genuine OEM switch ensures accurate calibration that generic parts often can't match. Orders placed before 3PM CST ship same-day to restore your heat fast.
