OEM Carrier Flame Sensor (48GS400192) for Model PY3PPA060130AB

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY3PPA060130AB gas furnace. The flame sensor is a critical safety component — a metal rod that generates a small DC microamp signal when it detects an active burner flame. When the sensor fails or becomes coated with oxidation, the furnace control board cannot confirm ignition, triggering a safety lockout. The telltale symptom: the furnace lights, runs for 5–8 seconds, then shuts down and repeats the cycle up to three times before locking out entirely.

• Specs: 90° mounting angle with bracket | Single-rod ionization/rectification design | Compatible with 24V control boards | Approximate dimensions: 4.9" L × 1.75" H × 1.6" W
• OEM vs Generic: This is a genuine Carrier factory part — not an aftermarket substitute. OEM sensors are manufactured to exact rod composition and geometry specifications, ensuring reliable microamp signal output and preventing nuisance lockouts that plague off-brand sensors.
• Install Difficulty: 2/5 — A straightforward repair for most homeowners. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers, fine steel wool or light sandpaper (to clean rod if reusing). Always shut off power and gas before servicing. Disconnect the lead wire, remove the single mounting screw, and swap the sensor.
• Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse.
