Replacing a belt on a Kenmore washer is a practical repair that saves money and extends the appliance's life. This task often becomes necessary when a whining noise or complete failure stops the drum from turning. With the right tools and a methodical approach, most homeowners can complete this project in under an hour.
Signs You Need a New Drive Belt
Before attempting the replacement, it is essential to confirm the issue is indeed a broken belt. A failing belt usually emits a high-pitched squealing or chirping sound during the spin or wash cycles. You might also notice the drum turning slowly or not moving at all when the machine is running. Visually inspecting the machine after removing the back panel will reveal a cracked, glazed, or snapped belt, making the diagnosis clear.
Safety Precautions and Preparation
Safety is the first step in any appliance repair. Unplug the washing machine from the electrical outlet to eliminate the risk of electric shock. Next, turn off the water supply valves connected to the hot and cold lines. Placing a towel or shallow pan beneath the washer tub will catch any residual water that might leak out when the machine is tilted, protecting your floor from damage.
Required Tools and Replacement Parts
Gathering the necessary items streamlines the process and prevents mid-project trips to the hardware store. You will typically need a set of screwdrivers, a socket wrench set, and a flashlight to illuminate the interior components. Ensure you purchase the correct replacement belt by checking the user manual or measuring the old belt's specific dimensions, including width and internal circumference.
Accessing the Washer Drum
To reach the belt, you must gain access to the rear of the machine. Start by removing the screws that secure the back panel and carefully set them aside. Slowly tilt the washer backward to rest on its top, securing it firmly to prevent it from falling. Once positioned, you will see the motor and the pulley system connected by the drive belt.
Removing the Old Belt
Locate the tension arm that presses the belt against the motor pulley. You will need to release this tension to slide the old belt off. Carefully push the arm inward or rotate the motor slightly to create enough slack. Slide the belt off the motor pulley first, then maneuver it over the main drum pulley. Inspect the pulleys for any debris or residue that could affect the new belt's performance.
Installing the New Belt
Take the new belt and route it around the largest pulley, which is the drum pulley, ensuring it sits securely in the grooves. Next, route the belt over the motor pulley, using your fingers to keep it aligned. This step is often the trickiest part, as you must guide the belt into place without crossing it. Double-check the routing diagram usually printed on the motor housing to confirm the correct path.
Testing the Tension and Completion
Before securing the back panel, you must ensure the belt has the correct tension. Push the motor toward the washer tub until the belt feels tight, then release it slightly; you should be able to turn the drum easily with minimal resistance. Once the tension is set, use the socket wrench to tighten the motor mounting bolts back in place. Reattach the back panel securely and plug the machine back in to run a test cycle, listening for smooth operation.
Troubleshooting Common Issues
If the washer still does not function correctly after the replacement, verify that the belt is not twisted or misaligned on the pulleys. A belt that is too tight will squeal loudly, while one that is too loose will slip off during operation. Ensure the pulleys are clean and free of lint or fabric buildup, as obstructions can cause the belt to wear prematurely and fail again.
