Understanding and maintaining the safety features of your home’s furnace is crucial in ensuring a warm, safe environment during the cold months. These features ensure efficient operation, prevent potential hazards and contribute to the longevity of your heating system. In this post, Perfect Degree HVAC, one of the top local HVAC contractors, you’ll know the most common safety features of furnaces.
The flame sensor is a critical safety feature in modern furnaces. It monitors the presence of a flame when the gas valve is open, ensuring that unburned gas doesn’t accumulate in the furnace. If the sensor doesn’t detect a flame, it signals the control board to close the gas valve, preventing potential gas leaks. This mechanism underscores the importance of a flame sensor in preventing hazardous situations that could result from unburned gas.
This is also another essential safety feature of a furnace. It serves as a fail-safe against overheating, which can cause significant damage to the furnace and potentially create a fire hazard. Its job is to sense the internal temperature of the furnace. If it exceeds a preset limit, the switch shuts down the furnace to prevent overheating. This automatic shutoff mechanism is crucial for maintaining a safe operation. A heating repair technician will check this along the other components of the furnace to ensure they are working properly.
This is a vital line of defense against carbon monoxide (CO), a colorless, odorless and deadly gas that a furnace can produce. If a furnace’s venting system malfunctions or becomes blocked, CO can build up in your home. The detector monitors the level of CO in your home and sounds an alarm if it detects excessive gas levels, providing crucial time to evacuate and address the issue.
Regular furnace maintenance is essential to ensure all safety features are working correctly. Maintenance checks should include inspecting and cleaning the flame sensor, testing the limit switch and ensuring the carbon monoxide detector is functioning properly. Not only does this promote safety in your home but also extends your furnace’s lifespan and improves its efficiency.
