A rattling noise coming from your dryer while it's running can be caused by various factors. Here are some common reasons for this issue:
Loose items inside the dryer: Check the dryer drum and the interior for any loose objects like coins, buttons, or small articles of clothing that may have fallen out of pockets. These items can cause rattling sounds as the drum rotates.
Loose or worn drum rollers: Dryers have rollers that support the drum as it turns. Over time, these rollers can become loose or worn out, leading to a rattling noise. You may need to replace the drum rollers if they are damaged.
Loose or damaged blower fan: The blower fan is responsible for circulating hot air in the dryer. If it becomes loose or develops cracks, it can create a rattling sound as it spins. Inspect the blower fan for any signs of damage and replace it if necessary.
Worn or damaged belt: The dryer's drum is typically turned by a belt. If the belt becomes worn or damaged, it may produce a rattling noise as it struggles to maintain tension and rotate the drum. A damaged belt should be replaced promptly.
Damaged drum bearing or glides: The drum bearing and glides support the dryer drum and help it rotate smoothly. If these components are worn out or damaged, they can cause rattling or squeaking sounds as the drum moves.
Loose panels or screws: Over time, the panels on the dryer can become loose, and screws may also come undone. This can result in rattling noises as the dryer vibrates during operation.
Debris in the vent or lint trap: A buildup of lint or debris in the vent or lint trap can cause airflow issues and create rattling sounds as the dryer operates. Make sure to clean the lint trap and check the vent for blockages regularly.
It's essential to address a rattling noise in your dryer promptly to prevent further damage and potential hazards. If you're unsure about how to diagnose or fix the issue yourself, it's best to contact a professional appliance repair technician to inspect and repair the dryer for you.
