Winter is here, meaning staying warm is of the utmost importance. A furnace that works efficiently and effectively is the key to ensuring that your home is a warm haven during the cold months. There’s nothing worse than coming home to a house that’s as cold as the outdoors, usually caused by a malfunctioning furnace.
The frustration can be overwhelming and can cause a great deal of inconvenience to home dwellers. Hence, knowing why furnaces stop working is crucial to prevent such situations.
In this guide, we will provide you with an overview of the top reasons why furnaces stop working. We will also discuss the importance of furnaces during winter and why ensuring they are working seamlessly is crucial.
Lack of Maintenance
Regular maintenance is essential to keep your furnace in top condition. It helps in identifying potential problems before they cause major breakdowns. During regular maintenance, professional technicians can detect and fix small issues before they escalate into major problems. It can result in significant savings in repair costs and can add life to your unit.
Regular maintenance also helps to keep your furnace running efficiently. A well-maintained furnace uses less energy, reduces your energy bills, and has less impact on the environment. It will also improve the indoor air quality of your home by reducing the amount of dust, debris, and pollutants in the air.
Simple Maintenance Tasks that Can Prevent Furnace Breakdowns
While some maintenance tasks require a professional technician, there are simple things you can do yourself to keep your furnace running efficiently. Here are some examples:
A thermostat is a device that regulates your home’s temperature, ensuring it remains at your desired temperature. It detects the temperature in your home and signals the furnace to turn on or off to keep the temperature constant. It also enables you to adjust and control the temperature with ease.
Symptoms of a Malfunctioning Thermostat
A malfunctioning thermostat can cause a lot of frustration and inconvenience by affecting the temperature inside your home. Here are some signs that could indicate a malfunctioning thermostat:
Importance of Replacing a Malfunctioning Thermostat
If you suspect your thermostat is malfunctioning, replacing it as soon as possible is essential. A malfunctioning thermostat can cause your furnace to run inefficiently, leading to higher energy bills and wear and tear on your unit. Replacing your thermostat with a newer, more reliable model can help prevent these issues and ensure that your furnace is regulating the temperature in your home effectively.
Pilot Light or Ignition Control Issues
A pilot light is a small flame that ignites the gas in your furnace. The pilot light’s flame is a permanent light responsible for heating the thermocouple, which signals the valve to open, allowing gas to flow to the main burner.
Causes of Pilot Light Failure
Several factors, such as a blown-out pilot light or a faulty thermocouple, can cause pilot light failure. Here are some common causes:
Overview of Ignition Control and Its Issues
Ignition control is responsible for managing the ignition sequence in your furnace. It starts by checking the thermostat setting and then initiates the ignition process by sending a signal to the gas valve. If the ignition control malfunctions, your furnace can fail to start or experience problems in the ignition sequence.
The issues with ignition control could result from several different factors. The most common causes of ignition control problems include faulty wiring, a malfunctioning fan limit switch, or a damaged control board.
Dirty or Clogged Air Filters
Air filters trap dust, debris, and other particles from circulating through your home’s air. These filters play a crucial role in maintaining your indoor air quality and improving the efficiency of your heating and cooling system. The filter captures these impurities and helps prevent damage to your furnace by protecting it from dirt and debris.
Symptoms of Dirty or Clogged Air Filters
Dirty or clogged air filters can cause a variety of problems, including:
Mechanical Wear and Tear
Furnaces are complex machines with hundreds of parts. Over time, these components can wear out, become damaged, or break down due to normal use and everyday wear and tear. Neglecting regular maintenance can also contribute to more significant mechanical problems in the long run.
Types of Mechanical Failures
Mechanical failures may occur due to factors such as age and lack of maintenance. These are some common types of mechanical failures:
Various factors, including dirty or clogged air filters, faulty wiring, damaged components, and mechanical wear and tear, can cause furnace problems. Regular maintenance is key to keeping your furnace in good working order. If you suspect that there may be an issue with your furnace, it’s best to contact a professional HVAC technician for assistance. They can diagnose the problem and help you find a solution to get your furnace back up and running quickly.
