LG Dryer has a burning smell

If your LG dryer smells like burning when it runs, do not ignore it. The most common cause is excessive lint collecting in the lint filter or venting, which can get hot and even ignite, so clean the lint screen and check the vent and ductwork first. A stretched or frayed drive belt that slips often produces a hot, burning odor next; while inspecting the belt, spin the drum and idler pulley to make sure they turn freely. Less common but still possible is a shorted main control board that overheats and emits a burnt electrical smell, so look for burn marks on the board. Some models use a blower belt; if the blower or blower belt is stuck or slipping it can also give off a burning scent. Worn idler pulleys or a failing idler assembly that stop turning let the belt slip and overheat. Turn off power before you inspect moving parts, and enter your model number on RepairClinic.com to find the exact replacement belt, pulley, board or lint filter for your dryer.

01 - LG 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.

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.
