Has your furnace left you out in the cold? Or maybe you’ve been noticed that your heater just hasn’t been acting right lately? Either way, you weren’t expecting it to happen! So, what can cause a furnace to stop working, and how can you prevent it from dying out too quickly? Let’s talk about it! In this blog post, we’ll discuss some of the most common reasons that heaters die quickly and unexpectedly. We’ll also tell you how you can prevent these issues from taking over and ruining your furnace.

So, What Can Cause a Furnace to Stop Working? Here’s are the Most Common Things that Will Ruin Your Furnace:

1). Lack of Maintenance

Imagine running a marathon without proper training – your furnace can feel the same way if it hasn’t been maintained regularly. Dust, dirt, and debris can accumulate over time, leading to clogs and inefficiencies. The solution? Schedule routine maintenance to keep your furnace in tip-top shape.

2). Thermostat Troubles

Before assuming the worst, check your thermostat settings. Sometimes, a simple switch from “cool” to “heat” can get your furnace back on track. Low batteries in your thermostat can also cause communication issues, so be sure to replace them regularly.

3). Dirty or Clogged Filters

A dirty or clogged filter can restrict airflow, making your furnace work harder and potentially overheating. Not only does this lead to a chilly house, but it can also increase energy bills. Regularly replace or clean your filters to keep the warm air flowing freely.

4). Pilot Light Problems

If you have an older furnace with a pilot light, it might go out occasionally. Relight it following the manufacturer’s instructions carefully. If it continues to extinguish, you may have a faulty thermocouple or gas supply issue, and it’s time to call a professional.

5). Ignition System Failures

What can cause a furnace to stop working if it’s relatively new? Newer furnaces use electronic ignition systems. If this system fails, your furnace won’t ignite. It could be due to a faulty ignition switch, sensor, or control board. A technician can diagnose and repair the issue.

6). Overheating

Furnaces have built-in safety features to prevent overheating. If your furnace frequently shuts down, it might be because of overheating caused by a dirty filter, blocked vents, or a malfunctioning blower motor. Always ensure proper airflow around your furnace.

7). Malfunctioning Blower Motor

The blower motor is crucial for circulating warm air throughout your home. If it’s malfunctioning, you might experience poor heating or no heating at all. A professional can assess and replace the blower motor if necessary.

8). Gas Supply Issues

What can cause a furnace to stop working if it runs on gas? If your furnace runs on natural gas or propane, it relies on a steady gas supply. Gas supply issues, such as a closed valve or gas line problems, can cause your furnace to stop working. Check for gas leaks, and if you suspect one, contact a technician immediately.

9). Faulty Sensors or Thermostats

Modern furnaces are equipped with various sensors and controls to regulate temperature and monitor system performance. Faulty sensors or a malfunctioning thermostat can lead to erratic furnace behavior. It’s best to have a professional diagnose and repair these issues.

10). Aging Furnace

Furnaces have a lifespan, typically around 15-20 years. If your furnace is nearing or past its prime, breakdowns become more common. Consider investing in a new, energy-efficient furnace to save on both repairs and energy bills.
