Description
The S1‑025‑35306‑000 is a flame sensor — an OEM‑quality component designed for gas‑fired furnaces and HVAC units. Its job is to detect the presence of a stable burner flame during furnace operation. When gas is supplied and ignition occurs, the sensor verifies that a flame is present; if at any time the flame extinguishes unexpectedly, the sensor signals the control board to shut off the gas supply. This safety functionality helps prevent unburned gas from accumulating, reducing risk of leaks or unsafe combustion.
Key Features
- Part Type: Flame Sensor / Gas Furnace Flame Sensor
- Function: Detects presence of burner flame; prevents gas flow if flame is absent or fails — ensures safe and stable combustion.
- Application: Gas‑fired furnaces / HVAC systems — replacement sensor for units originally built with this part number.
- Design & Construction: Compact flame‑sensor rod / probe — built to withstand furnace combustion environment; designed for easy installation in burner chamber.
- Compatibility: Fits various furnace models from York / Coleman / Luxaire that require a flame sensor with this part number.
- Safety Benefit: Critical for safe furnace operation — ensures that gas is not allowed to flow when flame is absent, preventing potential buildup of unburned gas and reducing fire or explosion risk.
