Microwave FAQ

NOTE: When experiencing problems with any appliance, the first thing the customer should do is check to see that there is power going to the unit by checking the breaker box.

Why do some foods come out with tough spots?

Because the microwave energy is beamed into the interior of the microwave and then dispersed by a metallic "stirrer," the pattern of the energy can be fairly consistent, rather than completely random. But this pattern sometimes causes certain portions of the food to overcook (creating tough spots) and others to undercook. A microwave oven with a carousel is far better at cooking the food consistently--the pattern becomes quite random while the carousel is turning.

Why is there a glass tray in the bottom of my microwave?

The glass tray has two proposes. It catches spills. It also raises the food off the floor of the microwave so that the microwave energy can reach the bottom of the food, too.

How can I tell if my unit is leaking microwave energy?

You can do a fair job with the inexpensive sort of tester that you can buy from a hardware store. To get a more accurate reading, contact a qualified appliance repair technician.

Are the microwaves in my oven dangerous?

Not usually. As long as the microwave oven door remains closed and you make no direct contact with the inside of the oven while the oven is on, the energy is safe. If you were to operate the microwave oven with the door open, it would be dangerous.

Can I make beef jerky in my microwave oven?

No. To make beef jerky takes an extremely slow drying and curing process.

Why do eggs, potatoes, and other things explode in the microwave?

Microwave energy penetrates foods much more deeply than conventional heating does. The water molecules inside the food heat as quickly as those on the outside. And water expands when you heat it. Eggs, potatoes, and other things with shells or skins explode because the expanding water has nowhere to go.

Does prolonged exposure to microwave energy cause health problems?

Some studies indicate a possibility for health problems with prolonged exposure to microwave energy. But most research has shown that it's very natural to be exposed to low-level microwaves--we get that exposure even from the atmosphere--without any adverse or lasting effects. Microwave ovens are required to meet very stringent federal government guidelines for leakage.
