Reznor 195292 Flame Sensor

As a seasoned technician, you know that a reliable Reznor 195292 Flame Sensor is the backbone of safe unit heater operation. This genuine OEM Reznor replacement part is engineered for high-precision flame rectification, ensuring your control board receives the necessary microamp signal to keep the gas valve energized. Designed specifically for Reznor UDAP, UDAS, UDX, and UDZ series heaters, this 4.25-inch sensor features a rugged porcelain insulator and a high-grade metallic rod that stands up to the intense thermal cycling of industrial environments. When dealing with "no heat" calls, a fouled or cracked HVAC flame sensor is a primary culprit for erratic ignition sequences. Replacing a worn component with this direct-fit 195292 sensor restores the safe combustion monitoring your equipment requires, preventing unburned gas accumulation and unnecessary 4-flash lockout codes on your DSI control board. Avoid the reliability issues of universal "will-fit" rods and stick with the factory-spec component built for Model UDAP/UDAS performance.

• OEM Compatibility: Exact replacement for Reznor 195292, ensuring seamless integration with existing DSI ignition systems.
• Precise Rectification: Delivers a consistent DC microamp signal (typically 3-6 µA) to the furnace control board for reliable flame proofing.
• Versatile Application: Fits a wide range of popular Reznor unit heaters including UDAP, UDAS, UDX, UDZ, UBX, and UBZ series.
• Industrial Build: High-temperature flame rod construction prevents premature oxidation and grounding issues.

• How do I know if my Reznor flame sensor is bad? If your heater ignites but shuts down after several seconds, it likely isn't "proving" the flame. Check for cracked porcelain or heavy carbon buildup on the 195292 sensor.
• Can I clean the 195292 flame sensor instead of replacing it? While light oxidation can be cleaned with a non-abrasive material, any cracks in the ceramic or deep pitting in the metal rod require an immediate OEM part replacement to ensure safe combustion.
• What units does this flame sensor fit? This part is the standard for Reznor gas-fired unit heaters, specifically the UDAP, UDAS, UDX, and UDZ models across multiple BTU sizes.
