Description
The Nordyne 903600 is an OEM replacement flame sensor complete with a pre-attached wiring harness, engineered to restore safe and reliable furnace operation. Flame sensors are a critical safety component in gas furnaces — they verify the presence of a burner flame and signal the control board to keep the gas valve open. A failed or fouled flame sensor can cause nuisance lockouts, short cycling, and no-heat calls, making this a high-demand service part for HVAC technicians.
Key Features
- OEM Nordyne replacement flame sensor for accurate fit and performance
- Includes pre-wired wiring harness for simplified installation
- Designed to detect burner flame and communicate with the furnace control board
- Helps prevent nuisance lockouts caused by a failed or contaminated sensor
- Direct drop-in replacement — no modification required
- Compatible with select Nordyne, Gibson, Frigidaire, Westinghouse, and Tappan branded furnaces
Why Replace Your Flame Sensor?
Over time, flame sensors accumulate oxidation and carbon buildup on the sensing rod, reducing their ability to conduct the small microamp current used to confirm flame presence. When the control board cannot detect this signal, it shuts down the gas valve as a safety precaution. Replacing the flame sensor with a genuine Nordyne part restores proper operation and eliminates unnecessary service calls.
