A Guide to Test and Replace the Belt Tension Roller on Your Kenmore Dryer

If your Kenmore dryer is making noise or isn’t spinning properly, the belt tension roller could be the culprit. Here’s a straightforward, step-by-step guide to help you test and replace it—no need for a repair call!

How to Identify a Faulty Belt Tension Roller

Before diving into a repair, it’s helpful to know if the belt tension roller is indeed the issue. Here are some signs that indicate the tension roller may need replacement:

• Squeaking or Squealing Noises: If you hear a high-pitched squeak or squeal while the dryer is running, it’s often a sign that the belt tension roller is worn out. The noise is caused by friction between the roller and the belt, especially if the roller bearings are damaged.
• Thumping or Rattling Sounds: A worn-out or misaligned tension roller may produce a thumping or rattling noise. This can happen if the roller no longer spins smoothly, causing uneven movement as the drum turns.
• Drum Not Spinning: If the dryer drum isn’t turning but you can hear the motor running, a faulty tension roller could be causing the belt to slip. The roller provides tension to keep the belt tight; without it, the belt may lose grip and prevent the drum from spinning.
• Visible Wear or Damage: Inspect the roller for visible signs of wear, like cracks, dents, or grooves. If the roller looks damaged or feels loose when you touch it, it’s likely time to replace it.

If your Kenmore dryer displays any of these symptoms, the belt tension roller may be the source of the problem. Identifying these signs early can help prevent further damage to your appliance and make the repair process quicker and more efficient.

Tools You’ll Need

• 1/4-inch nut driver
• Putty knife
• #20 Torx bit
• Small flat-head screwdriver

Safety Precautions

Safety is essential when working with any appliance. Follow these tips to ensure a safe and smooth repair:

• Power Off and Unplug: Always turn off and unplug your appliance before starting any maintenance. If your dryer is hardwired, switch off the circuit breaker. This prevents electrical shock.
• Allow Time to Cool: If the dryer was recently in use, give it enough time to cool down.
• Take Your Time: Avoid rushing through the repair to prevent accidents and ensure precision.
• Ensure Good Lighting: Work in a well-lit area so you can easily see and access all parts.
• Declutter the Workspace: A tidy workspace reduces hazards. Keep children and pets away for their safety.
• Dry Hands and Area: Never work on an appliance with wet hands or in a damp area to avoid electrical shock.
• Consult the User Manual: Check your user manual for specific installation or safety guidelines related to your model.
• Be Gentle with Parts: Handle components carefully to avoid damage and personal injury.
• Wear Insulated Gloves: These will protect your hands from sharp edges and debris.
• Exercise Caution with Wires: Avoid touching exposed wires or terminals. If you must, use non-conductive tools or insulating gloves.
• Document Connections: Take photos or make notes of wiring and terminal connections before you disconnect them, making reassembly much easier.
