The role of the mica plate is very important in a microwave. It protects the wave-generating parts from splashes, grease and liquid, and therefore avoids short circuits in electrical parts.

This plate may be dirty due to food splashes, or even pierced, burnt or broken. It often gets damaged due to lack of maintenance. To avoid this on your new hob, you can use the plastic cover to prevent splashes on the walls.

This part should be replaced if it is damaged, burnt and very dirty, or your microwave sparks.

The mica plate is fixed with tabs or screws inside the microwave cavity. It is generally located on one of the side walls, more precisely on the side of the control panel.

The mica plate or waveguide cover in your microwave plays a pivotal role in ensuring that your food is heated evenly by directing the microwaves into the main cooking compartment. However, over time, this plate can deteriorate, get burnt, or even accumulate food particles, leading to reduced efficiency. When this happens, it’s time to replace the mica plate. This article provides a step-by-step guide on how to change the mica plate of a microwave.

Note: Always prioritize safety when working with electrical appliances. If you are uncomfortable or unsure about performing this repair, please seek professional help.

Tools You’ll Need:

  • A new mica plate compatible with your microwave model
  • A pair of gloves
  • Screwdriver

Steps to Replace the Mica Plate of a Microwave

1. Safety Precautions: First things first, disconnect your microwave from the power source. This ensures that you’re safe from any electrical hazards.

2. Open the Microwave Door: The mica plate is usually located on the inside of the microwave, on one of the interior walls. Open the microwave door to locate it.

3. Removal of the Old Mica Plate: Depending on your microwave model, the mica plate may be held in place by a metal frame, screws, or it may simply be slotted into a holder. If there’s a frame, carefully unscrew it and put the screws aside. If there are no screws, you can simply slide the old mica plate out of its holder. Use gloves for this step to avoid cuts.

4. Clean the Area: Before installing the new mica plate, clean the area where the old plate was situated. This helps to remove any food debris or grease that might have accumulated over time.

5. Insert the New Mica Plate: Carefully slide the new mica plate into the slot where the old plate was removed from. Ensure that it’s properly aligned and fits securely. If your microwave model uses a frame, re-attach the frame using the screws you set aside earlier.

6. Test the Microwave: Once the new mica plate is securely in place, plug the microwave back into the power source. Turn on the microwave and observe whether it works without sparking or making unusual noises.
