OEM Carrier Flame Sensor (48GS400192) for Model PY1PPB036060ABAA

This is the factory OEM flame sensor for the Carrier PY1PPB036060ABAA gas furnace. The flame sensor — also called a flame rod — monitors burner operation by detecting the microamp rectified DC signal produced when gas is ignited. If the sensor cannot confirm a live flame within a few seconds of ignition, the furnace control board shuts off the gas valve and enters a safety lockout. A failed or contaminated flame sensor is one of the most common causes of a furnace that lights then shuts off after 5–8 seconds, followed by repeated lockout attempts.

• Specs: 90° bent rod design | Integrated mounting bracket | OEM part number 48GS400192 | Designed for Carrier / Bryant gas furnaces | Approx. rod length 1.6" | Overall dims approx. 4.9" × 1.75"
• OEM vs Generic: This OEM sensor is precision-manufactured to Carrier's exact rod geometry and alloy spec, ensuring proper microamp signal output at factory tolerances. Aftermarket sensors may produce marginal readings that trigger nuisance lockouts, especially as the sensor ages.
• Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" hex or nut driver, needle-nose pliers, multimeter (to verify microamp draw, typically 2–6 µA). Clean the rod with fine steel wool or emery cloth before condemning — oxidation buildup is the #1 cause of sensor failure.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
