why does my heater smell like burning? How to Fix it?

1. Dust in the Heater

One of the most common reasons for a burning smell coming from a heater is dust buildup. Over time, dust can accumulate in the heater, especially if it hasn’t been used for a while. When the heater is turned on, the dust can burn and produce a strong, unpleasant smell.

Fortunately, this problem is usually easy to fix. Simply turn off the heater and unplug it. Remove any accessible covers or grills and use a vacuum cleaner or a soft-bristled brush to clean out the dust. It’s important to make sure the heater is completely cool before attempting any cleaning.

2. Furnace problems

If the burning smell is coming from the furnace, there could be several possible causes. One common issue is a malfunctioning furnace filter. A clogged or dirty filter can cause the furnace to overheat and produce a burning smell. Another potential cause is a problem with the blower motor, which can cause overheating and burning odors.

In either case, it’s important to turn off the furnace immediately and call a professional HVAC technician to inspect and repair the unit.

3. Dirt and debris

If the heater has been sitting in storage for a while or has been exposed to a lot of dirt and debris, this can also cause a burning smell when the heater is turned on. In this case, the burning smell is caused by the dirt and debris burning off when the heater heats up.

To fix this problem, it’s important to clean the heater thoroughly before using it. Use a soft-bristled brush or a vacuum cleaner to remove any dirt or debris from the exterior of the heater. If possible, disassemble the heater and clean the interior components as well.

4. Electrical issues

If the burning smell is accompanied by smoke or sparks, this could indicate an electrical issue with the heater. Faulty wiring or damaged electrical components can cause a burning smell and pose a serious fire hazard.

In this case, it’s important to turn off the heater immediately and unplug it. Do not attempt to use the heater again until it has been inspected and repaired by a qualified electrician or HVAC technician.

5. Blocked airflow

A blockage in the airflow can cause the heater to overheat and produce a burning smell. This could be caused by a variety of factors, such as a blocked vent or a dirty air filter.

To fix this problem, it’s important to check the air filter and replace it if it’s dirty. Make sure that all vents and air ducts are clear and free of any obstructions. If the problem persists, call a professional HVAC technician to inspect the unit and diagnose the issue.
