Roper Dryer has a burning smell

If your Roper dryer has a burning smell, act quickly but stay methodical. The most likely cause is lint buildup in the lint filter or venting, which chokes airflow and can char fabric or ignite near the heating element; clean the trap and ducting first. Next suspect a stretched, worn or frayed drive belt that is slipping and producing a burning rubber odor — check that the drum and idler pulley turn freely and replace the belt if it shows damage. Less common is a shorted main control board or scorched component that emits an electrical burning smell, so inspect the control board for burn marks and replace it if necessary. Some models use a blower belt, and a seized blower or slipping blower belt can also overheat. A damaged idler pulley or idler assembly will let the belt slip and overheat as well. Clean lint and vents at least once a year, and enter your model number on RepairClinic.com to find the exact replacement part for your dryer burning smell.

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 - Roper 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.
Highly Likely

06 - Roper Dryer Idler Assembly

If your idler pulley assembly is damaged or doesn't turn, you should replace it. Replacing the drive belt is also recommended.
