Is your Kenmore dryer making unusual noises, not tumbling, or taking too long to dry clothes? These are common symptoms that often point to a worn-out or broken drive belt, a crucial component responsible for rotating the dryer drum. Fortunately, replacing this part is a manageable DIY project for most homeowners, saving you the cost of a service call.
This article will guide you through the step-by-step process of changing the drive belt on your Kenmore dryer. We'll cover everything from identifying the problem and gathering the necessary tools to safely disassembling the dryer, replacing the belt, and reassembling the unit. By the end of this guide, you'll have the knowledge and confidence to tackle this repair yourself and get your dryer back in working order.
Diagnosing a Broken Dryer Belt
The most common indicator of a broken or slipping dryer belt is the absence of drum rotation. When you start the dryer, you'll likely hear the motor running, but the drum itself will remain stationary. Another telltale sign is a distinct lack of tumbling action, meaning clothes aren't being agitated and exposed to the heated air effectively, leading to longer drying times and damp clothes.
Beyond the lack of tumbling, listen for unusual sounds. A broken belt might cause the motor to spin freely without engaging the drum, sometimes resulting in a high-pitched whining or a loud thumping noise as parts that should be connected are now loose. In some cases, a frayed belt might snag on other components, creating a scraping or grinding sound.
Visually inspecting the belt, if accessible, can also confirm the issue. If the belt is visibly snapped, frayed, or has melted sections, it's definitely the culprit. Even if it appears intact, a belt that has stretched significantly over time can lose its grip, causing it to slip on the pulleys and motor shaft, leading to the symptoms described above.
Gathering Your Tools and Parts
Before you begin, it's essential to have the right tools on hand. You'll typically need a Phillips head screwdriver, a flathead screwdriver, a nut driver or socket set (common sizes are 1/4 inch and 5/16 inch), pliers, and possibly a putty knife or trim removal tool to help release clips without damaging the dryer's housing. Safety glasses are also a must to protect your eyes from dust and debris.
The most critical part is the replacement drive belt. It's vital to order the correct belt for your specific Kenmore dryer model. You can usually find the model number on a sticker inside the dryer door, on the back of the unit, or in your owner's manual. Once you have the model number, search online appliance parts retailers or contact a local appliance parts store to find the exact belt. Using the wrong belt can lead to premature failure or damage to other dryer components.
It's also a good idea to have a small container or magnetic tray to keep track of the screws and small parts you remove. This will prevent them from getting lost and make reassembly much easier. Having a flashlight or work light can also be helpful for illuminating the interior of the dryer.
Disassembling the Kenmore Dryer
Begin by unplugging the dryer from the electrical outlet. This is a critical safety step to prevent electric shock. Next, you'll need to access the interior of the dryer. For most Kenmore models, this involves removing the top panel and then the front panel. The top panel is usually secured by screws at the back, often hidden under a small plastic cover. Once these screws are removed, the top panel can typically be lifted or slid backward to detach.
With the top panel off, you'll likely see the front panel secured by screws, often located at the bottom and sometimes around the control panel. Carefully remove these screws. Some models may have clips that hold the front panel in place; in such cases, a putty knife or trim tool can be used to gently pry the panel away from the dryer frame. Be patient and work slowly to avoid bending or breaking any plastic components.
Once the front panel is detached, you may need to disconnect a wire harness that connects the control panel to the main dryer body. Take a picture of the connection before unplugging it to ensure you reconnect it correctly later. The front panel can then be carefully set aside. Now you should have a clear view of the drum and the drive belt system.
Replacing the Drive Belt
Locate the old drive belt. It will be wrapped around the dryer drum and the motor pulley. You'll also notice a tensioning idler pulley, which keeps the belt taut. To remove the old belt, you'll need to maneuver it off the drum and the motor pulley. Sometimes, the belt might be so broken that it's already detached. If it's still intact but stretched, you'll need to work it off.
The new belt needs to be installed in the reverse order. Start by looping the new belt around the dryer drum. Then, identify the motor pulley and the idler pulley. You'll need to stretch the belt and guide it onto the motor pulley. This is often the trickiest part, as the belt needs to be under tension from the idler pulley.
To get the belt onto the motor pulley, you'll typically need to push the idler pulley away from the belt, creating slack. Once the belt is around the motor pulley, carefully release the idler pulley. The spring-loaded idler pulley will then snap back into place, applying the necessary tension to the new belt. Ensure the belt is seated correctly on all pulleys and the drum.
Reassembly and Testing
With the new belt in place and properly tensioned, you can begin reassembling the dryer. This process is essentially the reverse of disassembly. Reattach the front panel, ensuring any wire harnesses are reconnected securely. Refer to the pictures you took earlier if needed. Then, replace the screws that hold the front panel in place.
Next, reattach the top panel. Slide it back into position and secure it with the screws you removed earlier. Double-check that all panels are flush and that no wires are pinched. Once everything is reassembled, plug the dryer back into the electrical outlet.
Turn the dryer on and select a heat setting. Listen for the motor and observe if the drum is rotating smoothly. Run it for a few minutes to ensure the belt is tracking correctly and there are no unusual noises. If everything sounds and looks normal, your Kenmore dryer is repaired!

Frequently Asked Questions
How do I find my Kenmore dryer's model number?
The model number is usually located on a sticker inside the dryer door frame, on the back of the dryer cabinet, or sometimes on the inside of the kick plate at the bottom front. Check your owner's manual if you still have it.
Can I use a generic belt if I can't find the exact Kenmore belt?
It is strongly recommended to use the exact replacement belt specified for your dryer model. Generic belts may not have the correct length, width, or material composition, which can lead to improper tension, slippage, premature wear, or damage to other dryer components.
How long does it typically take to change a dryer belt?
For someone with basic DIY experience, changing a dryer belt usually takes between 30 minutes to 1.5 hours. The time can vary depending on the specific dryer model and your familiarity with appliance repair.
What if the dryer still doesn't work after changing the belt?
If the drum still doesn't tumble, double-check that the belt is correctly installed and tensioned by the idler pulley. If the belt is properly installed and the drum still doesn't move, the issue might be with the motor, the motor pulley, or the belt drive system itself, which may require further diagnosis or professional assistance.
Are there any other parts I should consider replacing while the dryer is disassembled?
While the dryer is apart, it's a good time to inspect other components. Check the idler pulley for smooth rotation and any signs of wear. Also, inspect the blower wheel for debris or damage, and clean out any lint buildup from the lint trap housing and exhaust vent.
