Carrier 50HJ401431 Flame Sensor

When you are troubleshooting a Carrier 50HJ401431 Flame Sensor on a commercial rooftop or packaged gas unit, you need an OEM component that delivers the exact microamp signal required by the integrated furnace control. This genuine Carrier replacement part is engineered for high-heat environments, featuring a high-grade stainless steel probe and a porcelain insulator that prevents tracking and electrical leakage. Whether you are dealing with a 581B, 48FC, or 48HC series unit, the 50HJ401431 ensures the control board accurately detects the flame through the process of flame rectification. Replacing a carbon-fouled or oxidized sensor is vital to prevent furnace short cycling and annoying nuisance shutdowns during peak demand. This direct-fit sensor handles the intense combustion safety monitoring necessary to keep gas valves open and systems running at 100% efficiency. Skip the generic "will-fit" rods that fail to reach the proper temperature threshold and stick with the OEM furnace flame sensor designed for your specific Carrier, Bryant, or Payne model.

• Precise Flame Rectification: Delivers accurate microamp feedback to the control board for consistent ignition verification.
• Commercial Grade Durability: The stainless steel rod resists oxidation and high-temperature scaling in heavy-duty commercial applications.
• Direct OEM Fit: Specifically designed for Carrier packaged units and rooftop systems, ensuring perfect alignment within the burner assembly.
• Safety Compliance: Acts as a critical gas furnace safety device to prevent the hazardous buildup of unburned gas.

How can I tell if my 50HJ401431 has failed or just needs cleaning?
If your unit ignites but shuts down after 2-5 seconds, use a multimeter to check for a microamp (µA) signal. If the signal is below 1.0 µA or dropping out, try cleaning the rod with a light abrasive pad. If the porcelain is cracked or the signal doesn't stabilize, the flame sensor must be replaced.

What causes a flame sensor to fail prematurely?
Heavy oxidation or soot buildup is common in environments with poor combustion air quality. This Carrier OEM part is built for longevity, but "ghost" signals or failures are often caused by improper grounding or a cracked insulator.

Is this part compatible with non-Carrier equipment?
While the 50HJ401431 is optimized for Carrier, Bryant, and Payne equipment, it is frequently used across various Packaged Rooftop Units (RTU). Always verify the specific mounting bracket and lead wire length before installation.
