How to Fix a Broken Microwave Plate

Summary: If you have a broken plate in your microwave, don’t worry – it’s easy to fix. Begin by unplugging the appliance and then removing the plate from the inside of the microwave. Check for any cracks or breaks, and inspect the axle and wheels that hold the plate in place. Once identified, replace any broken parts with new ones and reassemble the entire unit. Place the new plate back inside the microwave, plug it in, and test it out to make sure everything is working properly.

What Causes a Microwave Plate to Break?

There are a few different reasons why a microwave plate might break. However, one of the most common reasons is that the plate is old and has become cracked over time. While this is certainly not the only reason a plate might break, it’s important to remember that older plates are more likely to break than newer ones.

Another common reason for a broken plate is that the plate was placed in the microwave incorrectly. If the plate is not placed on the turntable correctly, it can cause the plate to break. This is usually due to the plate being placed on the turntable crooked or not being centered correctly.

Additionally, plates can break if they are not compatible with the microwave. This is often an issue with aftermarket plates that are not specifically designed for use with your particular microwave model. The other time this might be an issue is if you’re using a plate that is too small or too large for the microwave. Finally, plates can break if they are used for something other than food. If you’ve ever placed metal in the microwave, you know that it can cause sparks and potentially damage the microwave. The same goes for putting any other non-food items on the plate.

Why It’s Important to Fix a Broken Plate

If you’ve ever had a broken plate, then you know that it’s not only annoying but also dangerous. A broken plate can cause the food to spill, which can be a fire hazard. Additionally, broken glass in the microwave is a serious safety concern. Not only is it a choking hazard, but it can also cause cuts if you’re not careful. For these reasons, fixing a broken plate is important as soon as possible.

Another reason to fix a broken plate is that it can cause the microwave to work less efficiently. A broken plate can block the microwave’s path, making it harder for the food to cook evenly. Additionally, a broken plate can cause the turntable to stop working properly.

Finally, a broken plate can be unsightly. If you’re someone who takes pride in their kitchen, then you probably don’t want to leave a broken plate in the microwave.

Tools and Materials

You’ll first need to gather the tools and materials needed to fix the plate. For this job, you’ll need

  1. A new microwave plate
  2. A Phillips head screwdriver 
  3. A putty knife 
  4. A clean cloth
  5. A roll of duct tape

A Complete guide on How to Fix a Broken Microwave Plate

1. Unplug the Microwave

The first step is to unplug the microwave. You’ll need to do this even if the plate is not broken. This is because you’ll be working with the electrical components of the microwave, and you don’t want to shock yourself accidentally. So first, find the power cord and unplug it from the outlet. Then, find the power cord for the microwave and unplug it from the back of the microwave.

2. Remove the Broken Plate

Once the microwave is unplugged, you’ll need to remove the broken plate. To do this, first, locate the two screws that hold the plate in place. These screws are usually located near the edge of the plate. Once you’ve found the screws, use a Phillips head screwdriver to remove them. Next, carefully lift the plate out of the microwave. If the plate is broken, be careful of any sharp edges. Also, avoid touching the wires or any other electrical components.

3. Clean the Microwave

After you’ve removed the broken plate, it’s time to clean the microwave. First, use a putty knife to remove any food or debris that might be stuck inside the microwave. Next, use a clean cloth to wipe down the inside of the microwave. Be sure to get rid of any grease or dirt that might be on the surface. If there is any broken glass, be sure to remove it carefully.

Use a Putty Knife

4. Use Super Glue

If the plate is only cracked and not completely broken, you can try using super glue for a small crack. This is not a permanent fix, but it can hold the plate together until you can replace it. To use super glue, first, clean the area around the crack. Next, apply a small amount of glue to the crack. Then, hold the plate together for a few minutes until the glue dries. If the crack is large, you might need to use more than one layer of glue.

5. Use Duct Tape

If the plate is completely broken, you can use duct tape to hold it together. This is not a permanent fix, but it will hold the plate in place until you can get a replacement. Be sure to clean the surface of the plate before applying the duct tape. First, lay a strip of tape across the back of the plate. Then, place another strip of tape over the first strip, perpendicular to it. Repeat this process until the entire back of the plate is covered. Finally, use a piece of duct tape to secure the plate to the turntable.

6. Use epoxy

If you want a more permanent fix, you can use epoxy. This is a strong adhesive that will hold the plate together permanently. To use epoxy, clean the area around the break with rubbing alcohol. Then, mix together equal parts of epoxy resin and hardener. Apply the mixture to the break with a toothpick or other small object. Allow it to dry for 24 hours before using the microwave.

If the break is still visible, you can sand it down and paint the area to match the rest of the microwave. Avoid using the microwave until the epoxy has fully cured.

You Can Use Epoxy

7. Use JB Weld

If you’re looking for an even more permanent fix, you can use JB Weld. This is a two-part epoxy that will bond the plate to the turntable. It’s very strong, and it will take a lot of abuse. To use JB Weld, mix equal parts of the epoxy and hardener. Then apply it to the underside of the plate. Press the plate onto the turntable and hold it in place for a few minutes.

The JB Weld will take a few hours to cure, so you’ll need to leave the microwave alone for a while. Once the JB Weld has cured, you can use the microwave as normal. The plate should be firmly attached to the turntable and shouldn’t come loose again.

8. Get a Replacement Plate

If the plate is too damaged to be repaired, you’ll need to get a replacement. You can order a replacement plate from the manufacturer or from an online retailer. Be sure to get the correct model number for your microwave. Once you have the replacement plate, follow the instructions above to install it.
