Your furnace is an important appliance that helps ensure consistent comfort, especially during the colder months. It has safety features to protect itself when something out of the ordinary occurs. With these, you can rest easy knowing that you and your household are also protected from issues that might put your home at risk. Local HVAC and air duct sealing expert Acker Heating & Cooling takes a closer look at each one in this blog post.
A thermo-limit switch, or high-limit switch, is a safety device that monitors the temperature inside the furnace. If the temperature exceeds a predetermined limit, the limit switch shuts off the burner to prevent overheating. This helps protect the furnace from damage and reduces the risk of fire.
The flame sensor has a crucial role in maintaining furnace safety by confirming the presence of a flame when the gas valve is open. If the flame goes out while the gas is still on, the sensor sends a signal to shut down the valve, preventing a dangerous gas leak.
The venting system, or exhaust flue, expels gases created during the combustion process. This includes potentially lethal carbon monoxide. The system typically has a safety switch that shuts down the furnace if it detects a blockage in the vent, which would otherwise lead to a buildup of harmful gases.
If you have an electric furnace, you know that it has a fuse that trips or blows if there’s an electrical fault within the equipment. This mechanism is triggered to prevent potential electrical fires.
The pressure switch ensures that the furnace’s venting system is working correctly. If the pressure changes due to a blocked vent or a failing blower, the switch responds by shutting down the furnace to protect against a possible carbon monoxide buildup.
The air filter is the most visible and user-serviceable part of the furnace. A clean air filter not only provides better indoor air quality but also protects the furnace by keeping dust and debris from damaging the unit, which could become a potential fire hazard.
Regular inspections, including checking, are essential for the optimal performance of the furnace and its safety features. A professional HVAC technician can assess and address any issues and ensure that your heating system operates efficiently and safely throughout the year. With proper maintenance, homeowners can enjoy a warm and secure environment while minimizing the risk of malfunctions and hazards.
