York S1-025-30788-700 Flame Sensor

The York S1-025-30788-700 Flame Sensor is a crucial safety component in York gas-fired furnaces and boilers. It safeguards your comfort and peace of mind by continuously monitoring the presence of a flame during operation. Made from durable stainless steel, this sensor can withstand a wide temperature range of -40°C to 85°C. With a high sensitivity of 1.0-1.5 µA and compatibility with 24V systems, it ensures reliable flame detection. When a flame is detected, the sensor sends a signal to the control board, allowing the system to run safely. If no flame is detected, the sensor triggers a system shutdown to prevent a gas leak. This automatic shutoff protects your home from potential hazards and ensures efficient operation by preventing wasted fuel.
