Understanding Furnace Parts and Components

A furnace is made up of several parts and components, all working together to generate heat for your home. Understanding the parts of the furnace will help you understand how it works and how to identify problems.

The furnace consists of the blower, heat exchanger, gas valve, burners, and thermostat. The blower pushes air through the furnace and out into the home. The heat exchanger is a metal chamber that absorbs heat from the burning gas and circulates it through the home. The gas valve is responsible for controlling the flow of gas that enters the furnace. The burners are responsible for the burning of the fuel, while the thermostat controls the temperature.

Other components of the furnace include the igniter, pressure switch, and flue. The igniter is responsible for igniting the gas that is fed into the furnace. The pressure switch monitors the pressure inside the furnace to ensure it is operating properly. The flue is a vent that allows the exhaust from the burning fuel to be expelled from the home.

Understanding the parts and components of your furnace will help you identify potential problems and better understand how to properly maintain it. It’s important to seek professional help if you’re not sure how to troubleshoot any problems you may encounter.

Common Furnace Repairs

Furnaces can be a hassle to maintain due to their complexity and the amount of wear and tear they experience. Fortunately, the most common furnace repairs are simple and can be done without the help of a professional. Here are the most common furnace repairs and how to fix them.

The first and most common furnace repair is clogged filters. Clogged filters can cause the furnace to overheat and shut down, so it is important to replace them as soon as possible. To replace the filter, simply remove the old filter and insert a new one. Make sure to check the manufacturer’s instructions for the proper size and type.

The second most common furnace repair is a faulty thermostat. A faulty thermostat can prevent the furnace from turning on or cause it to overheat. To fix this issue, first check the wiring between the thermostat and the furnace and ensure that it is all connected properly. If the wiring is in order, then replace the thermostat with a new one. Once again, make sure to check the manufacturer’s instructions for the proper size and type.

The third most common furnace repair is a faulty pilot light. A faulty pilot light can cause the furnace to not turn on or to not produce enough heat. To fix this issue, first check the pilot light and make sure it is lit. If the pilot light is not lit, then follow the manufacturer's instructions for relighting it. If the pilot light is lit but the furnace is still not producing enough heat, then the burner may need to be cleaned or replaced.

These are the most common furnace repairs and how to fix them. It is important to take the necessary steps to ensure that your furnace is running properly and efficiently. If you are unable to fix the problem yourself, then it is best to contact a professional for assistance.
