Microwave FAQs

Are microwaves dangerous?
No. As long as the microwave oven door remains closed when in operation, there is no danger to you from the microwave energy. It is, however, important that you do NOT attempt internal/electronic parts repair. Due to the high risk of electrocution, only repair professionals should attempt such repairs.
In our home, we use our microwave a few times per day. Will prolonged exposure to microwave energy cause long-term health problems?
How can I test my microwave for leakage?
Why do eggs, potatoes and other foods explode when heated in a microwave?
What kind of microwave should I buy?
Can microwave ovens lose power over time?
When I heat food in my microwave, the food comes out with tough spots and cold spots. Why is that?

In our home, we use our microwave a few times per day. Will prolonged exposure to microwave energy cause long-term health problems?
Some studies indicate a possibility for health problems with prolonged exposure to microwave energy. However, most research has shown that it’s very natural to be exposed to low-level microwaves. We are regularly exposed to microwaves in the atmosphere – without any adverse or lasting effects. Microwave ovens are required to meet stringent federal government guidelines to prevent any leakage issues.
How can I test my microwave for leakage?
There are some test kits available at home improvement stores. However, if you have concerns about leakage, it’s best to contact a repair professional for an inspection.
Why do eggs, potatoes and other foods explode when heated in a microwave?
Microwave energy penetrates foods more deeply than during conventional heating. The water molecules inside of the food heats as quickly as those on the outside. When heated, water expands so skinned or shelled foods explode to accommodate the increasing size of the water molecules. To avoid overheating these types of foods, use your microwave’s preset cooking feature for more precise cooking times, or reduce the power level during cooking.
What kind of microwave should I buy?
The higher the wattage, the faster the microwave will heat food. Look for models with sensor cooking options to make heating more precise. Check out Consumer Reports and other credible sources for ratings on the latest models.
Can microwave ovens lose power over time?
No. Your microwave oven should perform as well as it did the day you brought it home.
When I heat food in my microwave, the food comes out with tough spots and cold spots. Why is that?
Because the microwave energy is beamed into the interior of the microwave and then dispersed by a metallic "stirrer," or by a rotating carousel, the pattern of the energy is usually consistent. However, certain portions of the food may overcook (creating tough spots) and others will undercook. A microwave oven with a carousel is far better at cooking the food consistently. It also helps to use the microwave’s preset cooking feature.
