How to replace mica for the microwave

One of the necessary elements of the furnace that allows the unit to fully function is a mica plate. It requires proper care, because without it the microwave will fail.

If this part is damaged, it must be replaced in a timely manner.

Replacing the mica plate

It is not difficult to find a plate that has become unusable. She is situated on the right side or upper wall of the NEH, painted gray, rough to the touch, has the shape of a rectangular plate.

During operation of the unit, this part performs a number of important functions:

• preventing contamination of the waveguide;
• distribution of microwaves evenly;
• protection of device parts from overheating.

A damaged plate will not allow household appliances to function fully. If inside the device sparks appear while it's running, it probably needs to be replaced.

Completing of the work

To replace you need:

• 
  open the door microwaves, wash plate and the space around it.

• Unscrew this element using a screwdriver or simply remove the latches.
• If place under mica turned out to be dirty, it is also necessary wash.
• Install a new plate. Depending on the mounting method, screw it to a free space using a properly selected screw, or insert it into special tabs in the case, snapping them into place.

On a note! You can make a mica plate for the microwave with your own hands.

To do this, take a piece identical material and cut out a rectangle corresponding to the template. Be sure to remove any unevenness by sanding the part. Drill holes for screws on the sides if this involves the mounting method.

After these procedures, the oven should function properly.

When should you change the mica in the microwave?

The reason for incorrect operation of the microwave may not be mica, but a failure of the waveguide or a breakdown of the magnetron. Therefore, before replacing, be sure to make sure that the part is faulty.

Advice! After removing the record, make sure that it is faulty.

External signsindicating the need for replacement:

• a large layer of fat on the surface;
• cracks or chips;
• partial or complete darkening;
• rusty or burnt spots.

If these signs are absent, the record should be washed and put back.

The procedure for installing a new part may not lead to the desired result. In this case, you need to call a technician or take the microwave to a service center.

How to replace a mica plate

If you cannot find a suitable element or simply want to experiment with new materials, then you can find an alternative mica.

But first you need to determine the secret of this substance in order to understand what the replacement should be.

Required qualities

The mica plate functions fully in the microwave oven due to the following properties:

• resistance to high temperatures;
• no accumulation of static electricity;
• ability Fine let off steam through the pores.

Accordingly, the material intended for installation must have these characteristics.

What can be used as a replacement?

At the moment, the most popular material instead of mica is food grade plastic. It is a good alternative, as it has a clear advantage over mica.

• Compared with standard material food grade plastic more resistant to high temperatures.
• He stronger, and provides less chance of burnout.
• This material more durable and has best performance characteristics.

His only disadvantage it could be considered high cost and inaccessibility. It is difficult to make a part made of food-grade plastic yourself, so you only need to make it to order.

However, in some workshops, replacements of this kind are already widely practiced. In addition, the high cost is compensated by a long service life.

How to extend the life of an element without replacement

In some cases, when the mica plate fails, it does not need to be replaced.

If, after removing this item, you do not notice any dark spots, rust or burnt areas on it, the situation can still be saved.

In this case, it may just be a matter of pollution. Then you need to take out the plate, clean it well, and also wash the area around it.

Then turn the part over to the other side and install it again. This way you can extend the life of the microwave part without replacing it.

Important! This trick will only work if the plate is not burnt out.

Regardless of the condition of the mica, all parts of the microwave oven require good care, timely repair and replacement of faults.
