How to Replace the Belt on a Whirlpool Washer: A Step-by-Step Guide
Replacing the belt on a Whirlpool washer is a manageable DIY project that can save you money. This guide explains the process of replacing the drive belt, a crucial component, ensuring the washer’s drum spins correctly and allowing the machine to function as intended.
Why Replace Your Washer Belt?
A faulty drive belt is a common culprit behind washing machine malfunctions. It’s responsible for transferring power from the motor to the drum, allowing it to agitate and spin. Over time, these belts can crack, stretch, fray, or even break, leading to several issues.
- Drum Won’t Spin: The most obvious symptom. Without a functional belt, the motor may run, but the drum remains stationary.
- Loud Noises: Squealing, screeching, or thumping sounds during operation can indicate a worn or damaged belt.
- Burning Rubber Smell: A severely worn belt may overheat and produce a distinct burning rubber odor.
- Washer Shaking Excessively: An unbalanced drum due to a slipping or damaged belt can cause excessive vibration.
Replacing a washer belt yourself can save you the cost of a professional repair, which can range from $150 to $300, or even the cost of a new washer. The belt itself typically costs between $10 and $30.
Identifying the Right Belt
Before you begin, it’s crucial to purchase the correct replacement belt for your specific Whirlpool washer model. Using the wrong belt can lead to poor performance or even damage your machine.
- Locate Your Model Number: This is usually found inside the washer door, on the back panel, or in the owner’s manual.
- Use Your Model Number to Find the Correct Belt: Visit an appliance parts retailer (online or in-store) and enter your model number to find the compatible replacement belt.
- Consider the Belt Type: Whirlpool washers use different belt types, including V-belts and flat belts. Ensure you’re purchasing the correct type for your machine.
Tools You’ll Need
Gather these tools to ensure a smooth and efficient belt replacement:
- New Replacement Belt: (The correct one for your washer model)
- Screwdriver Set: (Both Phillips head and flathead may be necessary)
- Socket Set or Wrench Set: (For removing panels and components)
- Pliers: (For manipulating hoses or wires if needed)
- Gloves: (To protect your hands)
- Work Light: (To illuminate the work area)
- Shop Towels: (For cleaning up spills)
- Optional: Nut Driver: (Can make removing certain screws easier)
Step-by-Step Belt Replacement Guide
Follow these steps carefully to replace the belt on your Whirlpool washer:
- Safety First: Disconnect the washer from the power outlet and turn off the water supply.
- Access the Washer’s Interior: Typically, you’ll need to remove the rear access panel of the washer. This usually involves removing screws with a screwdriver or socket wrench.
- Locate the Motor and Pulley System: The motor is typically located at the bottom of the washer, and the pulley system consists of a motor pulley and a larger drum pulley. The old belt will be connecting these two pulleys.
- Remove the Old Belt: Carefully inspect how the belt is routed around the pulleys. Sometimes it’s helpful to take a picture beforehand. Gently pry the old belt off the pulleys. If it’s broken, you may need to remove pieces of it from around the pulleys.
- Install the New Belt: Route the new belt around the pulleys in the same way the old belt was routed. This usually involves looping it around the motor pulley first, then stretching it to fit around the larger drum pulley. This may require some effort.
- Ensure Proper Belt Tension: The belt should be snug but not overly tight. Some washers have an idler pulley that automatically adjusts belt tension. If not, make sure the belt is properly seated in the grooves of the pulleys.
- Reassemble the Washer: Reattach the rear access panel and secure it with the screws you removed earlier.
- Reconnect Power and Water: Plug the washer back into the power outlet and turn on the water supply.
- Test the Washer: Run a test cycle to ensure the new belt is functioning correctly and the drum spins smoothly.
Common Mistakes to Avoid
- Not Disconnecting Power: Always disconnect the power before working on any electrical appliance.
- Using the Wrong Belt: Using an incompatible belt can cause performance issues or damage.
- Incorrect Belt Routing: Ensure the belt is routed correctly around the pulleys, as improper routing can cause slippage or premature wear.
- Over-Tightening or Under-Tightening the Belt: Proper belt tension is crucial for optimal performance.
- Neglecting to Inspect the Pulleys: Check the pulleys for wear or damage and replace them if necessary.
- Forcing the Belt: Avoid using excessive force when installing the belt, as this can damage the belt or pulleys.
Troubleshooting After Replacement
- Belt Slipping: If the belt is slipping, double-check the routing and tension. The belt may also be too loose or the pulleys may be worn.
- Washer Still Not Spinning: If the washer still isn’t spinning, the problem may not be the belt. Check the motor, clutch, or other components.
- Excessive Noise: Excessive noise can indicate incorrect belt routing, improper tension, or damaged pulleys.
- Burning Smell Continues: A persistent burning smell after replacing the belt could indicate another underlying problem, such as a motor issue. Consult a professional if the issue persists.
Frequently Asked Questions (FAQs)
How often should I replace my Whirlpool washer belt?
A typical washer belt lasts between 3 to 5 years, depending on usage and the quality of the belt. However, it’s best to inspect the belt regularly for signs of wear and replace it when needed, regardless of age.
Can I use a universal belt instead of a specific Whirlpool belt?
While some universal belts may fit, it’s strongly recommended to use a belt specifically designed for your Whirlpool washer model. This ensures proper fit, tension, and performance. Universal belts may not provide the same level of durability or performance.
What does it mean if my washer belt is shredded?
A shredded washer belt is a sign of significant wear and tear or a potential underlying issue. It could be caused by misaligned pulleys, excessive tension, or a worn-out motor. Replace the belt immediately and inspect other components for damage.
Do I need to lubricate the washer belt after installation?
Typically, lubrication is not necessary for modern washer belts. Applying lubricants can actually cause the belt to slip or degrade. However, check your washer’s manual for any specific recommendations.
How do I tell if my motor pulley is damaged?
Inspect the motor pulley for cracks, chips, or excessive wear. Also, check if it spins freely and smoothly. A damaged pulley can cause premature belt wear and performance issues, so replace it if necessary.
What is an idler pulley and how does it affect belt tension?
An idler pulley is a small pulley that helps maintain proper belt tension on some Whirlpool washer models. It automatically adjusts to compensate for belt stretch and wear, ensuring optimal performance. If your washer has one, make sure it is functioning correctly.
Why is my new washer belt squealing?
A squealing new washer belt could indicate improper installation, insufficient tension, or misaligned pulleys. Double-check the belt routing, tension, and pulley alignment. If the squealing persists, the belt may be defective.
Can I reuse the old belt if it’s not completely broken?
It’s not recommended to reuse an old belt, even if it appears to be in good condition. Old belts can be stretched, worn, or cracked, which can lead to performance issues and premature failure. Always replace the belt with a new one.
What are the signs of a worn-out drum pulley?
A worn-out drum pulley may exhibit signs of rust, corrosion, or wear on the belt contact surface. It may also feel rough or uneven. Replace the drum pulley if it shows signs of damage, as it can damage the new belt.
My washer belt keeps falling off. What’s wrong?
If your washer belt keeps falling off, the most likely cause is incorrect routing or insufficient tension. Double-check the belt routing and ensure it’s properly seated on the pulleys. The pulleys themselves may also be worn or damaged.
How do I adjust the belt tension on a washer without an idler pulley?
On washers without an idler pulley, you may need to adjust the motor position to achieve proper belt tension. Loosen the motor mounting bolts and shift the motor slightly until the belt is snug but not overly tight. Then, re-tighten the bolts.
Is it possible to overtighten a washer belt? What are the consequences?
Yes, it is possible to overtighten a washer belt. An overtightened belt can put excessive strain on the motor and pulleys, leading to premature wear and failure. It can also cause the motor to overheat. Aim for a snug but not overly tight fit.
