Why do microwaves have so many buttons?

Including so many buttons on the mid-tier product makes it look more like its expensive and feature-reach counterparts. In reality, most of these buttons simply set a duration and possibly a power level, if the microwave can change its wattage. These options may entice the buyer, but they confuse the user.

Why do microwave doors only open one way?

Robert McKechnie, manager of new product development for Electrolux and Frigidaire, told me that microwave ovens were originally designed to match side-open ovens, which were hinged on the left for ease of use by right-handed cooks. The tradition stuck around even with countertop and over-the-range models.

Why do most microwave ovens have turntables?

Many microwave ovens have turntables inside to help cook the food more evenly. If your microwave does not have one, a turntable accessory can be purchased to help prevent hot spots. You can determine where the hot spots are in your microwave by conducting a marshmallow test.

Are all microwaves the same?

None of this is to say that all microwaves are truly identical. Although the cheapest models are essentially generic ovens designed and assembled by Midea, some brands do play a part in their microwave designs.
