Description
The S1‑025‑30802-000 is a genuine OEM flame sensor designed for gas-fired furnaces and HVAC systems from York (and compatible brands). Its job is to detect the presence of a flame in the burner assembly — ensuring that once gas is supplied, ignition has successfully occurred before allowing the system to continue operation. If the flame sensor does not detect a flame, it signals the control board to shut off the gas supply to prevent unburned gas from accumulating, protecting the unit and occupants. As a safety-critical component, this flame sensor helps ensure safe and efficient combustion, stable ignition, and reliable furnace operation.
Key Features
- Function: Detects flame presence; if flame is absent or unstable, signals system to shut off gas flow — prevents gas leaks, unsafe combustion, and ensures safe operation.
- Construction / Material: Durable material suited for high‑temperature furnace environment (ceramic/suitable sensor materials as per typical flame sensors)
- Compatibility: Designed to work with various York-brand gas furnaces (or HVAC units that originally used this flame sensor part number) — ideal for repair or replacement.
- Safety Benefit: Helps safeguard against unburned gas, flame failure, and unsafe furnace operation by enforcing flame verification before gas continues to flow.
