When the weather is cold, the last thing you want is a furnace that is malfunctioning. There could be any number of reasons why your furnace stops working properly. You need a licensed HVAC contractor to professionally evaluate the system to determine what the problem is so it can be repaired. However, there are a few things you should check throughout the life of your furnace to help prevent the possibility of a broken furnace. Here are some things you can do:
Look at the Furnace Motor
A furnace has a motor that moves the warm air into your home. When the motor does not work, the air will be heated but cannot get inside your house to bring it up to a comfortable temperature. The thermostat will try to cycle the furnace on since the room temperature does not increase to your desired setting. What is worse is that the furnace can eventually overheat and cause more severe damage.
Look at the Flame Sensors
The flame sensors are vital to a furnace's safety system. The sensor will detect any flames while the gas valve is in the open position. If the furnace is not professionally maintained, your flame sensors will not function properly. These sensors can also get covered in dust or soot, which prevents them from being able to detect the possibility of fire. If the sensors work, they will engage if a fire occurs. You can have a flame sensor replaced quite easily at a low expense.
Look at the Thermostat Setting
Issues you may have with your furnace may have nothing to do with the mechanics of the system and more to do with your thermostat not working properly. The thermostat is the brains of the system by telling the furnace what to do. If the thermostat is not functioning correctly, the furnace will not know to heat the air for the home. If you have a digital display thermostat, you will be able to tell there is an issue if you notice anything blinking or if no information is showing.
A thermostat can easily be replaced. There are different thermostat options available that you can choose from. If possible, choose a thermostat designed to increase energy efficiency to help you save money on your utility bill.
If you have any issues with your furnace and you do not know what to do, be sure to make an appointment with your HVAC technician to have your system evaluated and diagnosed. It is best to repair any issues before they turn into a more severe problem.
