A clanging noise in a dryer can be caused by several factors. Here are a few common reasons:
Loose objects: Check the drum of the dryer for loose objects such as coins, buttons, or small metal items that may have gotten caught inside. These items can create a clanging sound as the drum rotates. If you find any foreign objects, remove them carefully to prevent further damage.
Drum support rollers: Dryers have drum support rollers that help the drum rotate smoothly. Over time, these rollers can wear out or become worn, causing them to produce a clanging or thumping noise. If the rollers are damaged, they may need to be replaced.
Idler pulley: The idler pulley is responsible for keeping tension on the dryer belt. If the idler pulley becomes worn or faulty, it can produce a clanging noise as it rotates. Inspect the idler pulley for any signs of damage or wear and consider replacing it if necessary.
Baffle or vanes: The drum of the dryer usually has baffles or vanes inside to lift and tumble the clothes. If a baffle or vane becomes loose or damaged, it can create a clanging sound as the drum rotates. Inspect the baffles or vanes and tighten or replace any that are loose or damaged.
Drive belt: A worn or damaged drive belt can cause noise in a dryer. If the belt is frayed, cracked, or stretched, it may produce a clanging sound as it moves against the components of the dryer. If the drive belt is the issue, it should be replaced.
Loose or worn parts: Over time, various components of the dryer, such as screws, nuts, or brackets, can become loose or worn. These loose parts can rattle and create a clanging noise during operation. Inspect the dryer thoroughly and tighten any loose components. Replace any worn parts as needed.
If you are unsure about diagnosing or repairing the issue causing the clanging noise, it is recommended to contact a professional technician or an appliance repair service to properly inspect and fix the problem. They have the expertise and tools to identify the source of the noise and carry out the necessary repairs.
