OEM Carrier Flame Sensor (50HJ401431) for Model PY1REA150224ADWA

This is the factory OEM replacement flame sensor for the Carrier PY1REA150224ADWA furnace. The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a burner flame and sends a small microamp signal to the control board to confirm ignition. When the sensor becomes coated with oxidation or fails entirely, the control board cannot verify a flame is present and will shut off the gas valve within 5 to 8 seconds of ignition as a safety precaution, causing a lockout condition. This is one of the most common causes of a furnace that "lights then goes out" repeatedly.

• OEM Part Number: 50HJ401431 | Factory-direct replacement | Exact fit for Carrier PY1REA150224ADWA
• OEM vs Generic: This OEM sensor is manufactured to Carrier's exact microamp output and rod geometry specifications. Generic sensors may produce inconsistent microamp readings, triggering nuisance lockouts or failing to satisfy the control board's flame-prove threshold.
• Install Difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect the single wire connector, remove the mounting screw, swap the sensor, and restore power. Always verify microamp signal (1.5–4 µA typical) with a multimeter after install.
