Rheem-Ruud 62-21744-01 Flame Sensor
The Rheem-Ruud 62-21744-01 Flame Sensor is a critical safety component designed for flame rectification in gas-fired furnaces, water heaters, and boilers. As a direct OEM replacement, this furnace flame sensor rod utilizes high-sensitivity metallurgy to detect the presence of a stable burner flame, sending a microamp signal back to the integrated furnace control board. If the sensor fails to verify ignition within the 4-second safety window, the system will trigger a gas valve shutdown to prevent unburned gas accumulation. Featuring a 2-3/64 inch rod length from the mounting flange to the sensor tip and a standard 1/4 inch male quick connect termination, the 62-21744-01 ensures a secure electrical path and reliable ignition verification. This sensor is compatible with a wide range of Rheem, Ruud, and Weather King spark ignition and induced draft units, including the RGDA, RGDD, and RGLS series. Frequent "no-heat" calls or short-cycling are often resolved by replacing a carbon-fouled or oxidized flame detection probe.
Key Benefits- OEM Precision: Guaranteed compatibility with Rheem-Ruud gas furnaces ensures accurate millivolt/microamp signal transmission.
- Enhanced Safety: Prevents hazardous gas buildup by confirming burner ignition before allowing continuous gas flow.
- Durable Construction: High-grade ceramic insulator and specialized metal rod resist thermal stress in high-temperature combustion chambers.
- Universal Compatibility: Fits many gas furnace models across Rheem, Ruud, and Corsair brands using the 62-21744-01 part number.
How do I troubleshoot a failing flame sensor?
If your furnace ignites but shuts down after 4 to 10 seconds, the flame sensor likely isn't proving the flame. Check for carbon buildup on the rod or a loose ground connection at the mounting screw.
What is the proper signal for the 62-21744-01?
Most Rheem control boards look for a steady DC microamp signal (typically 1.0 to 4.0 µA). A fluctuating or dropping signal often indicates a dirty rod or poor burner ground.
Does this sensor work with propane (LP) systems?
Yes, this flame detection probe is suitable for both natural gas and liquid propane configurations, provided the furnace model specifies the 62-21744-01 replacement part.
