To ensure your furnace runs its best, your a-coil needs to be clean.
If your home has a split-unit air conditioner, you will find an a-coil inside your furnace either above or below your blower. Even though you may not be running your air conditioner, air from the blower still needs to pass through the a-coil to heat your home. If your a-coil is dirty, your blower will have to work harder and you will be getting less air into your ductwork. For instructions on cleaning your a-coil, click here.
There are four main types of furnaces: natural gas, oil, electric, and propane. The most common type of furnace used is a natural gas furnace, because of its affordability and quick heating process. To understand what is causing your furnace to malfunction, it is important to be knowledgeable of how a gas furnace operates. Natural gas is connected to the furnace by a gas line. Once gas enters the furnace, the burner ignites it. Cold air from the house is brought into the furnace and warmed by the burning gas in the heat exchanger. The warm air is then sent through ductwork and into your home by the blower fan.
Check Your Limit Switch
A furnace fan should only run in the middle of a heating cycle. If it does not stop running even if your unit is not heating, then there might be an issue with the limit switch. The fan limit switch can be switched off manually in some models.
Check the manual or the automatic position to see if the same applies to your unit. If it is, follow the instructions and make the correct adjustments on your furnace. Troubleshoot: set the limit switch to auto to stop the fan from running continuously. If you have a malfunctioning limit switch, call your local hvac technician to take a look at your furnace.
A limit switch is a crucial device used in furnaces and heaters, and its function is to keep a check on the temperature of the heater and turning the blower fan on and off at the right times. A limit switch in poor condition may not know when to stop the blower from running, which will take a huge toll on your budget, and the blower’s lifespan. Want to know how to check if your limit switch is okay or not? here’s how: if your limit switch is open instead of closed (because that’s how they normally are), you may want to consider replacing it.
Ignition control problems can be a great source of frustration for many homeowners, especially during the cold winter months. These problems occur when there are dirty or clogged components of the pilot light system or when they are worn out. Additionally, there are times when the flame sensors are improperly positioned, which causes them to be unreliable during the ignition stage of heating the home. Various gas supply problems and electrical issues can also lead to problems with the pilot control, leaving you with challenges in using your furnace effectively.
