OEM Carrier Flame Sensor (90°) with Mounting Bracket for Model PY2PPB060090NB — Part# 48GS400192

This is the genuine OEM replacement flame sensor for the Carrier PY2PPB060090NB gas furnace. The flame sensor is a critical safety component that uses ionization/rectification technology to detect the presence of a lit burner flame. When the furnace fires, the sensor generates a small DC microamp current through the flame — if that signal is not confirmed within a few seconds, the control board shuts off the gas valve as a safety precaution. A failing or dirty flame sensor is one of the most common causes of a furnace that lights briefly and then shuts off after just 5–8 seconds, resulting in repeated lockout cycles and a no-heat condition.

• Specs: 90-degree rod configuration | Includes factory mounting bracket | Approx. dimensions 4.9" H × 1.75" W × 1.6" rod length | OEM Part# 48GS400192
• OEM vs Generic: This factory-genuine Carrier part ensures exact rod geometry, correct insulator material, and precise bracket alignment — all of which affect signal quality. Generic sensors may have inconsistent rod positioning that causes intermittent or false flame-out readings.
• Install difficulty: 2/5 — Turn off power and gas before servicing. Locate the sensor on the burner assembly, disconnect the single wire lead, remove the mounting screw, and swap in the new sensor. Tools needed: 1/4" hex or nut driver, needle-nose pliers. Tip: lightly clean the rod tip with fine steel wool before installation if reusing the bracket.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our stocked warehouse.
