Understanding Flame Sensors
Flame sensors play a crucial role in ensuring your furnace operates safely and efficiently. Knowing what these sensors are and how they function helps you maintain a reliable heating system.
What Is a Flame Sensor?
A flame sensor is a safety device in gas furnaces. It detects the presence of a flame when the furnace operates. Common types include flame rods, UV sensors, and photoelectric sensors. Each type has specific applications based on the furnace design.
How Does a Flame Sensor Work?
A flame sensor works by monitoring the flame produced by burning gas. When the furnace ignites, the flame produces infrared radiation or ultraviolet light. The sensor detects this radiation and sends a signal to the furnace control board. If the sensor doesn’t detect a flame, it triggers the safety mechanism to shut off the gas flow, preventing dangerous situations. This process allows the furnace to operate safely and efficiently while protecting you and your home.
