Why Does My Heater Smell Like It’s Burning?

If you notice a burning smell coming from the heater in your Sherman, Texas, home, don’t panic. Take steps to determine the cause. Here’s why your heater might smell like it’s burning:

Burning Dust

Burning dust is a common cause of a burning smell coming from your heater. It usually occurs when you turn your heater on for the first time in the winter. During extended periods of inactivity, dust settles on your heater’s burners, heat exchanger and other interior components. When you turn it on for the first time in several months, the hot air burns the dust, causing a burning smell to pass through the air vents and into your house. It’s nothing to worry about and should go away in a few hours. If it doesn’t, you may have a more serious issue that requires professional attention.

Clogged Air Filter

Dirt and dust accumulations on a clogged air filter can cause a burning smell when heat passes over it. Change your air filter, and the smell should go away. You should aim to change your air filter every three months. As a result, you’ll help to prevent strain and keep your heating bills as low as possible.

Overheated Blower Motor

An overheated blower motor is another possible — and much more serious — cause of an electrical burning smell. Typically, your furnace shuts off automatically if it overheats. If this safety feature malfunctions, your furnace may continue to run even as the motor overheats. If you suspect an overheated motor is causing the smell, turn your heater off and have it inspected.

Fried Circuit Board

A fried circuit board causes a gunpowder-like smell. This is a distinctive odor. You should immediately shut off your furnace if you notice it. Call an HVAC professional to check out your system before using it again.

If you notice a burning smell not caused by a dirty filter or dust accumulations, turn off your heater and give Adon Complete Air Conditioning and Heating a call at 903-482-4900. We’ll inspect your heater and get it fixed as soon as possible.
