What is the cardboard in my microwave?

The most common cause for a microwave oven not working at all is a blown main fuse. The microwave main fuse will cut the flow of electricity if too much current passes through it.

All microwaves have a magnetron cover, although the appearance will vary between models. On many Samsung microwaves, the magnetron cover may look like a piece of cardboard and you might wonder why it’s there.

If you take good care of your microwave up into its old age, there’s a low risk of harm, but if it’s damaged in any way you may want to get it checked out. If you’ve looked after it well, there’s no reason why a vintage microwave should be dangerous.

Leaving the microwave oven door open when not in use is not recommended because, on many microwaves, the light will stay on while the door is open. This shortens the life of the light. If you’ve just cooked something, it’s okay to leave the door open for a short time so that the steam can dissipate.

The average microwave oven lasts about seven years with normal use, and even less with heavy use and poor maintenance. A large family may find themselves replacing their appliance every four to five years as they become more reliant on its use to heat up snacks and leftovers, or to defrost meals.

Description: The recall includes GE combination microwave and conventional built-in wall ovens sold under the following brand names: GE, GE Profile and Kenmore. The ovens were sold in white, black, bisque and stainless steel. The brand name is printed on the lower left corner on the front of the microwave door.

Microwaves are absorbed by fat and sugar in foods. If metal is put into the appliance, the microwaves cause the electrons to move around, producing sparks and heat. Sparks occur simply due to a build-up of charged particles which produce a concentrated electric field at the edge of the metal object.

GE is one of the most reliable appliance brands and may last longer than the average seven years. There are a few things that can directly impact the overall lifespan of your GE microwave oven, including the way you use it and how you install it.

Note that your microwave oven is unlikely to explode if you place tin foil inside of it, but a fire is extremely likely even if the foil stays inside the microwave for a short period of time. However, if you accidentally microwave food in tin foil and miraculously don’t start a fire, your food will be safe to eat.

Prevents short circuits. Your microwave heats your food with a waveguide, which sends energy from the device to your food. When dirt or grease gets to this part, it creates a short circuit. The mica plate is placed in front of this conductor to prevent this.

It is safe to stand near microwave ovens even though they will leak radiation within a small radius. Standing two inches away makes it insignificant enough not to be life-threatening to humans. This is mainly due to FDA regulations and installed safety features, like a metallic grate in the door lining.
