Why Is My Furnace Overheating?

Furnace troubles can be a real menace during colder months, particularly when they start to overheat. An overheating furnace can not only cause distress, but it can also harm your health and safety if left unchecked. This article will explore the potential causes of furnace overheating and what to do if your furnace is overheating.

What Causes Furnace Overheating?

Furnace overheating is usually caused by a blocked airflow, leading to clogged filters or a fan that's not able to move enough air. This can cause the fan to work extra hard to cool the furnace, leading to overheating. Other potential causes of furnace overheating can include a high-efficiency filter, a dirty ignition system, an insufficient air supply, an unclean blower wheel, and a defective thermostat or igniter.

How to Detect Furnace Overheating

If your furnace stops working or starts to overheat, it's important to find out the cause. One of the clear signs of a furnace that's working too hard is increased humidity in the home, as well as unusual sounds like rattling or squealing as the fan attempts to move air. You may also see signs of obviously high heat or feel hot air around the furnace.

Troubleshooting a Furnace Overheating Issue

The first step in troubleshooting your furnace is to make sure the thermostat is set correctly. If the thermostat is set too low, your furnace will work longer and harder to cool the home, leading to overheating. You can also check the blower wheel, ignition system, and air filters to make sure none of them are blocked or unclean. If everything looks in order, then it may be time to call in a professional.

When to Call A Professional

If you've troubleshooted the basics and your furnace is still overheating, then it may be time to call in a professional. Furnace overheating can be caused by a serious issue, like a broken or blocked heat exchanger, which should be inspected and fixed by a professional.

In such instances, you should call a reliable and certified appliance repair professional to take a look at your furnace. You can rest assured that the best way to tackle an overheating furnace is to enlist the service of an appliance specialist who can diagnose and fix the issue. They will be able to take your furnace from an overheating furnace to a furnace that functions smoothly once again.
