Description
The York S1-SCP-9007053 Flame Sensor is an essential component used in gas-fired heating systems to confirm the presence of a burner flame during operation in HVAC systems. It is positioned within the burner assembly. It monitorS flame conductivity and sends a signal to the control board to verify successful ignition. If no flame is detected after ignition is attempted, it initiates a shut-off of the gas valve to prevent unburned gas from accumulating. It is an essential safety component that support controlled combustion, reliable ignition sequencing, and safe heating system operation.
