Dryer Smells Like Burning? Causes and What to Do

A Burning Smell from Your Dryer Needs Immediate Attention

If your dryer smells like something is burning, don’t ignore it. A burning odour from a clothes dryer can range from a minor lint buildup issue to something that poses a genuine fire risk. Dryers are one of the most common appliances involved in house fires across Australia, and most of those fires start with overheating caused by restricted airflow or a failed component. Turn the dryer off, unplug it, and read through the possible causes below. If you can’t identify and resolve the issue yourself, book a dryer repair online — this is one fault you don’t want to sit on.

Why Does Your Dryer Smell Like It’s Burning?

Lint Buildup in the Exhaust System

This is the most common — and most dangerous — cause. Every time you run a dryer cycle, tiny fabric fibres are released from your clothes. The lint filter catches most of them, but fine particles make it past the filter and accumulate in the exhaust duct, the vent hose, and the internal ductwork around the heating element. Over months and years, this lint builds up and restricts airflow. Lint is extremely flammable, and when it accumulates near the heating element or exhaust path, it can char, smoulder, or ignite. If you smell burning and haven’t cleaned your exhaust system recently, this should be your first suspect.

Cleaning the lint filter before every load is essential, but it’s not sufficient on its own. The exhaust duct that runs from the back of the dryer to the external vent needs periodic cleaning too — at least once a year, or more often if you run your dryer frequently. In Brisbane’s climate, many households use dryers less in summer and more during the wet season, which means lint from heavy winter use can sit in the duct for months before the next season.

Foreign Object Caught in the Drum

Small items like hair ties, coins, buttons, tissues, or even small pieces of plastic can fall out of pockets and lodge between the drum and the outer casing. As the drum rotates, these items can rub against the felt seal or the drum itself, generating friction and a burning smell. You might also hear a scraping, clicking, or tapping sound. Stop the dryer and check the drum thoroughly — sometimes the object is visible inside the drum, but it can also slip into the gap between the drum and the front or rear panel where you can’t easily see it.

Worn Drum Seals or Felt Strips

Dryers use felt strips or rubber seals where the drum meets the front and rear panels. These seals prevent hot air from escaping and clothes from getting caught in the gap. Over time, the felt wears thin or tears, and clothes or small items can contact the stationary panel while the drum rotates. This friction generates heat and a burning odour — sometimes accompanied by scorch marks on clothing. If you’re finding marks on your clothes that weren’t there before washing, worn seals are a strong possibility.

Faulty Heating Element

Electric dryers use a resistive heating element to warm the air blown through the drum. If the element develops a short — where part of the coil contacts the housing — it can overheat locally, scorching nearby lint or insulation. A failing element might also glow unevenly, with some sections getting much hotter than designed. Our technicians can test element resistance and visually inspect for hot spots, damaged coils, or grounding faults.

Failing Motor or Drive Belt

The drum motor and drive belt work together to rotate the drum. A motor that’s overheating due to worn bearings or a seized bearing will produce a hot, electrical burning smell. A slipping drive belt — one that’s stretched, glazed, or misaligned — generates friction heat and a rubber-like burning odour. If you hear squealing, grinding, or the drum seems to rotate slower than normal, the motor or belt is the likely source.

Thermostat or Thermal Fuse Failure

Dryers have safety thermostats and thermal fuses designed to cut power to the heating element if the temperature exceeds safe limits. If these components fail, the element can run unchecked, pushing temperatures well above normal operating range. The excess heat can scorch lint in the system and produce a burning smell. This is a particularly dangerous failure because the safety system designed to prevent overheating has itself failed.

What to Do Right Now

Step 1: Turn the dryer off immediately and unplug it from the power point. Do not restart it until you’ve identified the cause.

Step 2: Check the lint filter. If it’s heavily clogged, clean it thoroughly. Check the filter housing for any lint that’s made it past the filter.

Step 3: Disconnect the exhaust hose from the back of the dryer and check for lint buildup. If you can see daylight through the external vent, the duct is probably clear. If not, it needs cleaning.

Step 4: Look inside the drum for any foreign objects. Run your hand around the drum edges and the door seal to feel for anything lodged in the gaps.

If you can’t find an obvious cause, or if you found significant lint buildup in the exhaust system, book a professional inspection. Our technicians will check the internal components — heating element, thermostats, motor, belt, and seals — that you can’t easily access from the outside.
