My Heater Smells Like Burning Plastic: 4 Possible Reasons Why and What to Do About It

The average American spends over $2000 on home maintenance each year. One of the most common costs is repairing or replacing home appliances.

In some cases, people find that their heater smells like burning plastic. Heater odors can be cause for concern and require heater repair services, but not everybody understands the reasons behind this occurrence. Let’s explore the key information you should know.

1. Accumulation of Dust

This is frequently why people notice a burning smell from their heaters. Since people often don’t use their heaters during warmer months of the year, dust accumulates over time.

This dust eventually builds up on components like burners and heat exchangers. When you finally turn the heater on again, you may find that it gives off a burning smell. In most cases, the dust will burn away after you activate the heater.

If you continue to notice this odor, call a heater repair professional for assistance. Just be sure to research your potential options.

2. Dirty Vents

Similar to dust accumulation, having dirty vents can lead to burning smells. The same can be said about having old furnace filters.

In these cases, burning smells are often accompanied by musty odors. It can be tempting to check out the ductwork yourself, but this is not something you should try on your own.

3. Electrical Problems

Fortunately, electrical issues can sometimes arise within residential heaters. This is a serious problem that needs immediate attention, as electrical complications could lead to the system overheating.

In extreme cases, it could catch fire and cause substantial damage to your property. If you suspect wiring issues, turn off your heater immediately.

Call a reputable HVAC technician to handle the problem. Under no circumstances should you attempt to fix the issue on your own. This carries an extreme risk that could result in bodily harm.

4. Something Lodged in the System

This isn’t nearly as common as the other problems on this list. However, it’s not an impossible occurrence.

Objects most often become lodged in the system due to children. Kids are notoriously curious about their surroundings, and they might place an item inside the heating system.

Over time, the heat from this appliance could melt the object and emit a burning odor. The good news is that these objects are often easily removed.

In some cases, they may have melted so badly that they adhere to the components of the heater. A professional can help you remove this mess and get things back on track.
