Repairing microwave oven

Use your microwave with no insulation to absorb heat. The magnetron (the main component) will be damaged and will need to be replaced. It is essential for you to check for some of the best convection ovens in the market because it helps you use them for a long time. There are few microwave oven brands who are known to offer the best products with DIY solutions in place.

You shouldn’t place metal in a Microwave that isn’t a Combination Oven. A Microwave can produce an electric charge that can spark or flash in the Oven Cavity. Any metal item placed in it will experience flashing or sparking. It will cause damage to the Magnetron (see above), and it will also leave marks on both the oven lining and the inner door screen. Refer to the instruction manual for more details.

Cover any vents. You can put things on top of your Microwave as long as the vents aren’t blocked. Microwaves must have adequate airflow to ensure safety. Any restriction can cause damage.

Avoid wiping the Microwave’s keyboard with a damp cloth. This can cause moisture to enter the keypad, eventually causing it to malfunction. Spray polish is silicon-based, so it’s better to use a duster.

Different types of problems faced in Microwave oven

The microwave works normally but it won’t heat up.

This could be due to many reasons, including the magnetron main part at a price between PS60* and PS70*. This isn’t a common problem! It is most likely a bad connection or a simple fault with the door switch.

The microwave is dead

If the Microwave isn’t working, it’s worth checking the fuse. If the Microwave doesn’t turn on, it may be due to one of the smaller components (Capacitor at PS20 and PS30, or Diode at PS10 and more).

Sparkling Microwave

You should not place any metal containers or utensils in the Microwave. There may be grease deposits in the oven cavity, the turntable wheels, or the grill element.

Sparkling Microwave Cover

Wave guide cover is also known by the name cardboard. This is a piece of special material that covers the Microwave radiation entry point into the oven. If it is damaged or missing, it can cause Magnetron damage. The Microwave should be stopped before the Wave guide cover (approximately PS6) has been replaced.

The turntable does not revolve…

Faulty turntable motor (about 18) or turntable shaft (about 10).

Radiation from microwave radiation can cause serious health problems. It is important to check for radiation leakage after any repairs are made or magnetron fixings have been damaged.

Routine Service and Radiation Leakage Testing should be performed at least once per month to ensure safe operation of your Microwave. Over time, microwave ovens can leak due to wear to the hinges or door catches. Even if the door seals are not being used, wear can cause them to become damaged.

Customers with a Cardiac Pacemaker or I.C.D are advised to ensure that their Microwave is working properly as Microwave Radiation can cause interference.

Oven heats up to much

The oven might not heat up properly, regardless of temperature settings. This could be a problem with the thermostat (PS40-PS50).

Oven does not heat at all

The problem could be a fan oven that works normally when the fan is on and the temperature light is on, but produces no heat. This is about PS45.

This holds true even for conventional ovens that aren’t fan assisted. There are two elements. You will have heat, but not enough heat to cook (PS20-40 per element).

Grill, not heating…

Most likely, the element (PS40-50)* or the grill thermostat (PS25).

Grill won’t turn down…

Your grill thermostat is not working properly (around PS25).

The fan oven is very noisy

It could be caused by wear to the fan motor (PS60-PS70). This is important because oven elements can overheat and explode if they seize

I can sense the air coming out of my Fan oven door..

Either the hinges have worn (40-PS50*), or the oven door seal is loose (about PS25*).

Inner Glass has been removed from the Oven Door

A new door is not necessary. The inner glass can be rebonded to the door structure.

Heating Characteristics

This can lead to microwave ovens heating up too quickly and cooking only the outside of frozen foods. Frozen food’s interior will not be affected. Another example of uneven heating is baked goods with berries. Because these items absorb more energy than the bread around them, and don’t have a high thermal conductivity, they can’t heat up. This causes berries to be overcooked in comparison to other foods. The “defrost oven setting”, which is marked with a low power setting, allows heat to transfer from regions that absorb heat more quickly to areas that heat slower. Place food off-center on a tray to heat it evenly.

Microwave heating can be designed to be inconspicuously uneven. For certain microwavable packaging such as pies, microwave heating can be designed in an uneven way. These materials can include aluminum-flake or ceramic-flake containing material. This absorbs microwaves and heats them up, thereby converting microwaves to less penetrating Infrared. This helps in baking and crust preparation by concentrating more energy there. These ceramic patches are attached to cardboard and often appear smokey gray or blue. They are easy to recognize because of this. Microwavable cardboard packaging may include overhead ceramic patches. The technical name for these microwave-absorbing patches is “susceptor”.

How do I know if my cookware is safe for the microwave?

The manufacturer’s label can be read to find out what it says. If your cookware or dish is made from crystal, metal-rimmed Crockery or melamine, or metal, or straws, you should not microwave it. Some plates and cookware can be microwave-safe while others cannot. All ceramics, clay, pottery, or china must follow the same rules. It is crucial to advertise or label microwave-safe plastics.

If you have questions regarding microwave safety, please contact the manufacturer.

Is there a cooking method that I can’t do in the microwave oven?

Microwave ovens lack temperature control and are not suitable for deep frying foods. Only microwaves with a grill insert can brown, crisp or grill. You can bake in a microwave/convection oven, or combination oven.
