The switch acts as a critical safety device, confirming exhaust gases are vented correctly; when it fails or sticks open, the furnace locks out and won't fire, leaving you without heat. This factory-calibrated switch trips at the precise pressure your unit demands, ensuring safe operation and guarding against hazardous venting conditions. Manufactured to Carrier specifications, it matches the original port layout and mounting for an exact fit on the LC350TM400570. Installation is straightforward, generally taking 15-25 minutes with basic hand tools and careful hose routing. Always disconnect power before servicing. A genuine OEM switch delivers accurate calibration that generic replacements frequently miss. Orders placed before 3PM CST ship same-day to restore your heat quickly.
