Common causes of a burning smell from a dryer include lint buildup or a failing thermostat, motor, or belt. According to the U.S. Fire Administration, appliances and electronics start 24,200 house fires yearly. About a third of fires related to dryers are caused by excess lint buildup, so it's time to investigate.
Steps to Address the Issue: Stop Using the Dryer: If you notice a burning smell, stop using the dryer immediately to prevent any potential safety hazards. Inspect for Lint: Clean the lint trap thoroughly and check the exhaust vent and dryer duct for lint buildup. Remove any accumulated lint to improve airflow.
Lint Buildup: Accumulated lint in the lint trap, exhaust vent, or dryer duct can create a fire risk. Lint is highly flammable, and if it comes into contact with the heating element or other hot components, it can cause a burning smell.
Overloading the Dryer: Wet sheets are heavy, and if the dryer is overloaded, it can cause the motor to overheat, leading to a burning smell.
If you overload the machine, the rubber belt is put under stress. It will slip and begin to wear. When it does, it will let off a burnt rubber smell.
Burning Smell #3: Rubber
A burning rubber smell means that a hose or belt has somehow gotten loose or broken and is touching something hot, resulting in it either burning or melting. Either way, it can cause issues – melted hoses can cause leaks, and melted belts can do major damage to your engine.
Pumps, pulleys, and motors have to work harder when the machine is heavy and overloaded. This can cause those components to wear out faster than usual and may lead to a burning smell when they need replacement. Be sure not to overfill your washer and keep heavier items to a small load size.
My Gas Dryer Smells like Gas
If you open your dryer early in the cycle and smell gas or can smell it on your clothes, that's a sign that your igniter is going bad. This ventilation issue can be caused by a dirty filter or an exhaust system breach.
Clothes dryers typically last for about 10 to 13 years. If your dryer has been around for nearly a decade, you will likely be searching for a replacement soon. Ancient dryers should get the boot, as older machines can actually cost you more money. Newer, certified models use less energy, helping you save on costs.
While there are many causes, electrical fires can smell like “burning plastic” or “burning rubber” as the plastic insulation surrounding copper wires inside the walls starts to heat and melt, releasing strong unpleasant chemical odors. If the electrical fire progresses, you may begin to smell wood burning as well.
One of the most common culprits behind a smelly dryer is lint buildup (we know it's the main culprit for almost anything dryer-related!). While most of us regularly clean the lint screen, lint can accumulate in harder-to-reach areas, which can trap moisture and begin to smell musty or mildewy.
When you turn on your heater and the heat exchanger warms up, the dust will burn off, producing that burnt smell. The smell should dissipate within a few minutes. However, this means there's a build-up of dust inside the furnace and ducts. You should schedule a duct cleaning.
How Do You Know if the Dryer is Too Hot? The tell-tale sign that your dryer is too hot is damage to your clothes. If you pull your clothes out of the dryer and notice that there are burn marks on them, your dryer is running far too hot. If your dryer is hot to the touch, that may be another sign of too much heat.
Idler Assembly Replacement
When you smell a burning odor coming from your dryer, a worn or broken idler assembly could be causing the smell. A bad idler assembly won't tension the drive belt on the drum properly so the belt will slip across the drum and get hot quickly.
Dryer repair costs will vary depending on the issue. For example, it will cost much less to replace a dryer belt than a motor. That said, if your clothes dryer is more than halfway through its lifespan—7 years or more—and the repair costs more than 50% of the price of a new one, you should consider replacing it.
Banging, popping, squealing or grinding noises are telltale signs that a dryer is broken. If you're hearing banging and popping, the usual culprit is a worn-out belt. As a dryer belt wears down over time, it can cause the drum to move erratically and create the noises you're hearing.
Observe your dryer's efficiency.
Start paying close attention to how your appliance is working. If your clothes are coming out damp, for instance, it might mean that they just need a little more drying time, or it could indicate a problem with the dryer's heating elements.

Clean the condensor and filters
A build up of lint and fluff in your dryer can lead to a burning smell. Check the filter found in the door recess and remove any fluff build up, also remove the lower cover to reveal the condenser.
There are two things that can cause that: Lint building up inside dryer and catching on fire. Fumes from painting or staining getting pulled into your dryer.
A burning smell coming from the washing machine during or after the spin cycle indicates a possible stuck drain pump in which its pump motor won't turn. With that, it may generate a burning smell. Warning: When you smell a burning odor from the washing machine, immediately turn it off to avoid further accidents.
Phantosmia refers to any smell you detect that isn't actually there. For some people, these odors are pleasant, like freshly baked sweets. But most people describe unpleasant smells, such as: Burning rubber.
