OEM Carrier Flame Sensor (48GS400192) for Model PY1PJB048130ABAA

This is the factory OEM replacement flame sensor for the Carrier PY1PJB048130ABAA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification to confirm that the burner has successfully lit. If the control board doesn't receive the expected microamp signal from this sensor within a few seconds of ignition, it shuts off the gas valve and locks out the furnace. A dirty or failed flame sensor is one of the most common causes of a furnace that lights and then shuts off after 5–8 seconds, often accompanied by repeated ignition attempts and a fault code on the control board.

• Part Number: OEM Carrier 48GS400192 | 90-degree flame rod with integrated mounting bracket | Compact form factor: approx. 4.9″ L × 1.75″ H × 1.6″ W
• OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket substitute. OEM sensors are manufactured to exact microamp output tolerances required by the Carrier IFC control board. Aftermarket sensors can read inconsistently, causing nuisance lockouts even with a healthy flame.
• Install Difficulty: 1/5 — One of the easiest furnace repairs. Tools needed: 1/4″ hex driver or flathead screwdriver, needle-nose pliers. Turn off power and gas, remove the single mounting screw, unplug the connector, swap the sensor, and reconnect. Clear any fault codes from the control board after installation.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
