Over time the sensing element accumulates oxide and carbon, weakening its microamp signal until the furnace lights briefly then locks out—classic short-cycling that leaves you without reliable heat. This exact-fit factory replacement restores a strong, stable signal and stops nuisance shutdowns for good. Made to Carrier's precise rod geometry and high-temperature alloy, it resists corrosion and reads consistently far longer than generic substitutes. Installation is an easy, beginner-level repair: shut off power and gas, remove the single screw, disconnect the lead, and mount the new sensor without touching the metal rod with bare fingers. Combine with a fresh igniter for a full ignition-system tune-up. Replacing a dirty flame sensor is the quickest, lowest-cost cure for intermittent no-heat faults.
