That high-pitched shriek emanating from your laundry room? It's not a banshee, it's your dryer, and that squealing sound is a clear sign something needs attention. A malfunctioning dryer not only disrupts your laundry routine but can also lead to more significant problems down the line, potentially damaging your clothes or even posing a safety hazard. Ignoring the problem will only make it worse, and a costly repair bill could be just around the corner. Fortunately, many common causes of dryer squealing are easily fixable with some simple DIY troubleshooting.
This annoying noise is often the result of a loose component, worn-out part, or a simple build-up of lint. Before you call a repairman and shell out hundreds of dollars, follow the step-by-step guide below to diagnose and resolve the squealing in your dryer yourself, saving time and money in the process.

Common Mistakes to Avoid
1. Forgetting to unplug the dryer
Reason: Working on electrical appliances while they're plugged in is extremely dangerous and can lead to electric shock.
Solution: Always unplug the dryer from the power outlet before starting any repairs.
2. Ignoring the lint trap
Reason: A clogged lint trap can restrict airflow, leading to overheating and squealing, even after other repairs.
Solution: Thoroughly clean the lint trap and check the exhaust duct for blockages before and after other repairs.
3. Over-tightening screws or components
Reason: Over-tightening can damage parts or strip threads, worsening the squealing or causing new problems.
Solution: Tighten screws firmly but avoid excessive force; use a torque wrench if available for precise tightening.
FAQs
My dryer is squealing, but it still seems to be drying clothes. Do I need to fix it immediately?
While your dryer might still function, a squealing noise often indicates a problem that will worsen over time. Ignoring it could lead to more expensive repairs, or even damage to your clothes or the dryer itself. It's best to address the squeal sooner rather than later.
