It generates a microamp signal that tells the control board flame is present; when the sensor oxidizes or cracks, the board shuts down the burner as a safety measure, causing short-cycling or no-heat conditions. Engineered as a direct-fit replacement for Carrier model LC348TM401844, it restores reliable ignition without modification. Installation is straightforward for a handy homeowner or technician: shut off power and gas, remove the single mounting screw, swap the sensor, and reconnect the lead—typically a 15-20 minute job. Always verify proper grounding and clean any adjacent surfaces for a stable flame signal. Using a genuine OEM part ensures correct microamp output and long service life versus generic alternatives. In stock and ships same-day when ordered before 3PM CST, so you can get your heat back fast.
