Understanding the Dryer Knob Shaft

If you’re facing a broken dryer knob shaft, it’s essential to understand the part’s anatomy to fix it correctly. The knob shaft connects the dryer control knob to the control panel, allowing you to adjust the settings.

The knob shaft has a flat side that fits into a matching slot in the control panel, ensuring that the knob rotates the shaft and changes the dryer’s settings. The knob shaft sits atop the dryer’s timer shaft, which tells the dryer when to start and stop. The knob shaft also includes a spring that helps return the knob to its original position when released.

When the knob shaft breaks, you’ll have trouble adjusting the dryer’s settings, and your dryer may not work correctly. A broken knob shaft is usually caused by excessive force being applied while adjusting the knob. Over time, the shaft’s plastic can become brittle and crack, causing the knob to separate from the shaft.

Note: If you’re unsure whether the knob shaft is the problem, check for other issues first. Make sure the dryer isn’t overloaded, the lint filter is clean, and the door switch is functioning.

Assessing the Damage

Before beginning the repair process, it’s essential to assess the extent of the damage to your dryer knob shaft. Here are some steps to help you evaluate what’s wrong:

  1. Check the knob: Start by inspecting the knob and checking if it’s spinning correctly or feels loose. If the knob is wobbly or doesn’t turn smoothly, there might be an issue with the shaft.
  2. Test the shaft: Turn the knob and try to operate the dryer. If the shaft is broken, you won’t be able to start or stop the dryer by rotating the knob. Also, the knob may come off entirely, indicating a failed knob shaft.
  3. Physical examination: If you still can’t tell what’s wrong, remove the knob and the control panel to inspect the shaft visually. Look for signs of significant wear and tear on the knob shaft, such as deep scratches or cracks. If you notice any of these, you probably have a broken dryer knob shaft.

It’s essential to assess the damage correctly before moving forward with the repair process. Doing so will ensure you have the necessary tools and supplies to complete the repair successfully.

To access the broken dryer knob shaft, we need to disassemble the dryer control panel. Before beginning, make sure that the power to the dryer is turned off and the unit is unplugged from the outlet. Safety first!

Now, let’s get started. Follow these steps to safely disassemble the dryer control panel:

  1. Locate the screws that are holding the control panel in place. These are typically located on the back of the control panel.
  2. Using a screwdriver, carefully remove the screws. Be sure to keep track of where each screw goes, as they may be different sizes or shapes.
  3. Once all screws are removed, gently pull the control panel forward. You may need to wiggle it a bit to release it from the clips holding it in place.
  4. Be careful not to pull too hard on any wires or connectors that are attached to the control panel.
  5. Once the control panel is loosened, you should be able to access the broken dryer knob shaft.

With the dryer control panel disassembled, you now have access to the broken knob shaft. Follow these easy steps to remove it:

  1. Locate the retaining clip that secures the knob shaft to the control panel.
  2. Using a pair of pliers, carefully remove the retaining clip.
  3. Pull the knob and shaft away from the control panel.
  4. If the shaft is still stuck, gently wiggle it back and forth until it comes loose.

Be careful not to apply too much force or twist the shaft too hard. This could cause further damage to the control panel or other parts of the dryer.

Tip: If you’re having trouble removing the knob shaft, try applying a small amount of lubricant to the base of the shaft. This can help loosen it up and make removal easier.

Finding a Replacement Knob Shaft

Now that you’ve removed the broken knob shaft, it’s time to find a suitable replacement. Before purchasing the part, check the brand and model of your dryer to ensure compatibility. You can find this information on the dryer itself or in the manual.

There are several options for obtaining a replacement knob shaft:

  • Purchase directly from the manufacturer
  • Order online from an appliance parts retailer
  • Find a local appliance repair shop and purchase in person

When selecting a replacement knob shaft, make sure to choose one that matches the dimensions and specifications of your dryer. The part should fit securely and operate smoothly.

Some replacement parts come with a set screw included, while others require a separate purchase. Make sure to check the package contents before purchasing to avoid any additional trips to the store.

Installing the New Knob Shaft

Now that you have a replacement knob shaft, it’s time to install it. Follow these easy steps to complete the repair:

  1. Take the replacement knob shaft and insert it into the opening where you removed the broken shaft. Make sure it’s securely in place and fits snugly.
  2. If necessary, apply some lubricant to the shaft to ensure smooth movement.
  3. Align the flat side of the shaft with the flat side of the knob and slide the knob onto the shaft.
  4. Tighten the screw onto the shaft’s threaded end with a screwdriver until the knob is snugly in place.

You’ve successfully installed the new knob shaft! Before reassembling the control panel, take a moment to test the shaft’s movement. Gently turn the knob to ensure it’s aligned correctly and performs as expected.

Pro Tip: Before you start removing the broken knob shaft, take a picture of the control panel and the knob with your phone. This can help you remember how everything is positioned when you start putting the pieces back together.

Reassembling the Dryer Control Panel


Congratulations on successfully removing the broken knob shaft and installing the replacement! Now it’s time to reassemble the dryer control panel.

Follow these steps to safely put everything back together:

  1. Take the control panel cover and align it with the control panel.
  2. Reattach any screws or clips that were removed during the disassembly process.
  3. Attach the new knob onto the shaft.
  4. Slide the knob assembly onto the control shaft and ensure it fits properly.
  5. Reattach the knob onto the control panel with a screw.
  6. Replace the control panel back onto the dryer and fix it in place with screws.

Once you’ve completed the reassembly, plug the dryer back in and turn it on to test the repaired knob shaft. Ensure the new knob rotates smoothly and adjusts the dryer settings properly.


Always unplug the dryer from the electrical outlet before disassembling it. This will prevent any electrical shocks or injuries. Safety should be your top priority throughout the entire repair process.

  3. Check temperature: Set the dryer to the highest temperature setting and allow it to run for several minutes. Check to make sure that the temperature is maintaining a steady level. If it’s fluctuating significantly, it may indicate a problem with the thermostat.
  4. Check timer: Set the timer on the dryer for a few minutes and check to make sure it’s counting down correctly. If it’s not, it may indicate a problem with the dryer’s electrical system.
  5. Test the repaired knob shaft: Finally, test the repaired knob shaft by turning it in both directions. It should turn smoothly without any resistance.
