Burner control knobs are made of heavy heat-resistant plastic or stainless steel, making them quite sturdy. However, they can crack, chip, or break due to accidents or constant use. If a burner control knob is damaged, it may be unable to rotate the surface element switch stem, causing the burner to remain on or off. To fix a burner control knob, you can either clean, repair, or replace it. Before performing any repairs, ensure the power to the stove is cut off to prevent the risk of shock and electrocution.

What You'll Learn
Removing the knob
Before attempting to fix your electric burner control knob, it is important to cut the power to your stove to avoid the risk of electrocution. You can do this by pulling the plug or switching off the breaker that powers your stove. You may also need to pull your stove out and away from the wall to access the back. Place a towel or a large piece of cardboard underneath the front feet of your stove to prevent scratching the floor.
Now, you can start by removing the burner knob that is giving you trouble. This could be one knob or the whole set. If the knob is stuck, you can try wrapping a bit of flexible wire around the prong behind it and gently tugging it out. Be very careful when doing this, as too much pressure can bend the prong or damage other parts of the ignition system. If the knob is stuck firmly in place, it is best to call a professional to avoid causing further damage.
Once the knob has been successfully removed, you can take the opportunity to clean behind it. The knob itself may also be dirty, so you can soak it in warm soapy water and use a sponge or cloth to scrub away any grease, drips, or grime. You can also use a rag to polish the surface. If there are any compartments that you cannot reach with a sponge or cloth, these may be filled with grease, which could be the reason why your knob is not functioning properly.
If your knob is cracked or broken, you will need to replace it. Universal replacement knobs are available with multiple adapters, so you can find one that fits your electric range. You can also use moldable glue to repair the knob by pressing and molding it into the desired shape, then allowing it to cure for 8-24 hours.

Cleaning the knob
Before attempting to clean the knob, ensure the stove is switched off and unplugged. It is also recommended to wear protective mitts or gloves to prevent any burn injuries.
To clean the knob, start by removing it from the stove. In most stove models, the control knobs can simply be pulled off. If the knob is stuck, wrap a bit of flexible wire around the prong behind it and gently tug. Once the knob is removed, drop it into a sink full of warm soapy water and let it soak for a few minutes. Use a sponge to scrub away any grease, drips, or grime. For stubborn stains, a mixture of vinegar and baking soda can be applied to the knob. Spread the mixture on the knob and let it sit for 10 to 15 minutes before scrubbing with a non-abrasive scrubber or sponge.
It is important to note that you should not use any abrasive materials, such as metal scouring pads, as these can damage the surface of the knob. Additionally, be careful not to get any electrical components of the knob wet, as this could damage it.

Replacing the knob
Before replacing the knob, it is important to clean the area. Start by removing the burner knobs. Drop them into a sink of warm, soapy water and let them soak for a few minutes. Use a sponge to scrub away grease, drips, and grime. You can use a rag to polish the surface.
Now, you can remove the broken knob. In most stove models, the control knobs can be pulled right off. If the knob is stuck, wrap a bit of flexible wire around the prong behind it and gently tug. Be careful not to use too much force, as this may damage the prong or other parts of the ignition system. If the knob is very stuck, call a professional to avoid causing further damage.
Once the knob is removed, clean the area behind it. Spray an all-purpose cleaner or degreaser over the knob shafts and control panel. Scrub the panel and shafts with a nylon sponge to remove any grease and grime. Rinse with clean water.
Now, you can attach the new knob. Slide the adapter that best fits your electric range model onto the shaft. Then, push the new control knob onto the adapter. Make sure the knob is positioned so that "off" points to the opposition on the range.
Finally, test the new knob for durability by turning it on and off slowly and then quickly.

Repairing the knob with glue
Before repairing the knob with glue, it is important to clean the knob thoroughly. Start by removing the burner knob and soaking it in warm soapy water. Use a sponge to scrub away any grease, drips, or grime. You can then use a rag to polish the surface. This step is crucial as the buildup of grease and residue could be the reason why your knob is not functioning properly.
Once the knob is clean and dry, you can proceed with the repair. If the plastic knob has cracked, chipped, or broken, you can use moldable glue to fix it. Take a small amount of the glue and warm it in your hands like clay or putty. Roll it into a ball and then flatten it into a thick sheet. Press the glue onto the broken areas of the knob and mould it into the desired shape. Allow the glue to cure for 8-24 hours, following the instructions on the package.
If you are reattaching a knob that has come loose, you can use regular glue. Apply the glue to the broken area and hold the knob in place with a clamp for 1-4 hours. After this time, you can remove the clamp, but you should wait a full 24 hours for the glue to completely cure before testing the knob.
When using glue to repair your burner control knob, it is important to choose the right type of glue for the material of your knob. Most knobs are made of heavy heat-resistant plastic, but some are made of stainless steel. For plastic knobs, epoxy glue is a good option. You can also use a glue gun, which will create a strong bond but be careful as it gets very hot. For stainless steel knobs, you may need a stronger adhesive, such as a metal epoxy or super glue.
Remember to exercise caution when working with any type of glue, and always follow the manufacturer's instructions and safety guidelines.

Adding new markings
If the markings on your electric burner control knob have worn away, you can add new ones. Firstly, remove the burner knob. You may need to use a flat-head screwdriver to help pop it away from the control panel surface. Next, clean the knob with warm soapy water, scrubbing away any grease or grime with a sponge. Dry the knob with a cloth and, if necessary, repeat the process until all residue has been removed.
Now you can begin to add the new markings. Take a small, sharp knife or craft blade and slice a line on the dial at each of the major setting points. This will help you to reposition the knob correctly when you are adding the new markings. You can then use paint to add the new markings. Alternatively, you could use a foil sticker, although these are more prone to peeling or flaking over time. Allow the paint to dry completely before reattaching the knob.
If you are unsure about the correct positioning of the new markings, you could take a picture of the model number tag with your smartphone. This will allow you to refer to the correct positioning when you are adding the new markings.
