Share This Post

If your furnace stops working, it’s important to troubleshoot the issue as soon as possible. After all, you rely on your furnace to keep your home warm during the colder months. There are several potential furnace problems that could be to blame, but fortunately, most of them are relatively easy to fix.

In this comprehensive guide, we’ll show you seven expert solutions to common furnace problems. We’ll cover everything from troubleshooting a pilot light that won’t stay lit to fixing a furnace that’s blowing cold air. So whether you’re a first-time furnace owner or a seasoned veteran, this guide will help you get to the bottom of your furnace problems and get your heat back on as quickly as possible. Let’s get started!

Here are seven expert solutions to furnace problems:

1. Check the Pilot Light

One of the most common furnace problems is a pilot light that has gone out. If your furnace won’t turn on, check to see if the pilot light is lit. If it’s not, relight it according to the instructions in your furnace’s owner’s manual.

2. Clean or Replace the Furnace Filter

A dirty furnace filter can restrict air flow, causing your furnace to work harder than it needs to. As a result, your furnace may not heat your home as efficiently as it could. To prevent this problem, clean or replace your furnace filter at least once a month.

3. Check the Thermostat

If your furnace won’t turn on, it could be because the thermostat is set to the “off” position. Make sure the thermostat is set to “heat” and that the temperature is set above the current room temperature.

4. Inspect the Blower Belt

If the furnace is running, but the air isn’t circulating, the problem could be a broken blower belt. Inspect the belt to see if it’s broken or frayed. If it is, you’ll need to replace it.

5. Clean the Burners

If the furnace is running, but the air isn’t getting hot, the problem could be dirty burners. Over time, dirt and dust can build up on the burners, causing them to work less efficiently. To clean the burners, turn off the furnace and remove the access panel. Then, use a brush to clean the burners.

6. Check for Leaks

If the furnace is running, but the air isn’t getting hot, the problem could also be a gas leak. To check for a gas leak, turn off the furnace and smell for gas near the furnace. If you smell gas, call your gas company immediately.

7. Call a Professional

If you’ve checked all of the above and the furnace is still not working, it’s time to call a professional to take a look at it. An HVAC contractor will be able to troubleshoot the problem and let you know what needs to be done to fix it.
