Dryer has a burning smell

If your dryer smells like something is burning, start with the usual suspects: lint build up in the lint trap and venting, which can char or ignite and is the most common cause of a dryer burning smell. Next check the drive belt — a stretched, frayed or slipping belt can overheat and give off a hot, burning odor; while you are in there make sure the drum and idler pulley turn freely. A shorted main control board or scorched electrical component is less common but serious, so inspect the board for burn marks and replace it if you see damage. Some models use a blower belt that can slip or seize and smell like burning, and a worn idler pulley or idler assembly that no longer turns can cause the same symptom. If you need parts, enter your model number on RepairClinic.com to find the exact replacement parts and step-by-step repair instructions for your dryer.

01 - Dryer Lint Filter

Excessive lint build-up in the dryer can be a fire hazard. The element or burner can cause the lint to catch on fire. It is recommened to clean out the dryer and dryer venting at least once a year.

02 - Dryer Drive Belt

03 - Dryer Main Control Board

A dryer's main control board controls the voltage being sent to all of the appliance's electrical components. The board itself can become shorted and produce a burning smell. You should inspect the board for any burn marks or a shorted components and replace if necessary.

04 - Dryer Blower Belt

Some dryer models use a belt to run the blower. If the blower gets stuck or the blower belt is worn, loose and slipping, it can produce a burning smell. Confirm the blower turns freely and replace the belt if needed.

05 - Dryer Idler Pulley

The idler pulley keeps tension on the belt to prevent it from slipping. If the idler wheel is damaged or stops turning, the belt can slip on the drive pulley, producing a burning smell. If your idler pulley is damaged or doesn't turn, you should replace it. Replacing the drive belt is also recommended.
