Part of the functional design is the spinning turntable in the middle. That spin is not just to show off your food as it cooks. It’s to distribute the microwave’s heat evenly throughout the dish.
Does microwave need to rotate?
Absolutely. One problem with microwaves is that they heat unevenly (as pointed out by Shane). The turntable is there to make the heating a bit more even but it has absolutely no impact on food safety. … If the turntable didn’t spin, the food won’t be cooked evenly, and will have hot spots and cold spots.
Why does a microwave spin both ways?
Rather, the reversal has to do with the relatively inexpensive turntable motors designed for use in most microwaves, said Robert J. … By design, they reverse their direction of rotation if a load greater than their output torque, or twisting force, is present, he said.
Is a microwave turntable necessary?
Not necessary, but useful. The nature of a microwave oven is that it will have “hot spots”, not because of the oven itself, but because of the shape and size of the food that’s in it (so it varies). The turntable keeps you from having to fidle with the food to some extent.
Is it safe to use a microwave without a turntable?
You should be able to safely use most microwaves even if the tray is not moving. You may need to use manual settings and monitor the cooking more closely. If the shaft of the tray drive mechanism is broken, it should not cause any operational problems in the microwave.

Is a flatbed microwave better than a turntable?
In fact, a major benefit of the flatbed design over and above a turntable, is that they tend to cook and heat food more evenly. They simply do away with the hassle of having to constantly reheat to get rid of those cold patches at the bottom of your leftovers.
What way do microwaves spin?
The turntable can turn in either direction when the microwave starts cooking. For example, the tray might rotate clockwise one time and counter-clockwise the next, or turn clockwise twice in a row. Electrical circuitry causes this direction change, and is normal.
What is the wavelength of a microwave?
Microwaves have frequencies ranging from about 1 billion cycles per second, or 1 gigahertz (GHz), up to about 300 gigahertz and wavelengths of about 30 centimeters (12 inches) to 1 millimeter (0.04 inches), according to the Encyclopedia Britannica.
How do microwaves work?
Microwaves are produced inside the oven by an electron tube called a magnetron. The microwaves are reflected within the metal interior of the oven where they are absorbed by food. Microwaves cause water molecules in food to vibrate, producing heat that cooks the food.
Where can I buy a microwave turntable?
Microwave Turntable Trays – Walmart.com.
Why do many microwave ovens have turntables?
3 Answers. Microwave ovens have a turntable because the microwaves themselves form what are known as ‘standing waves’. This means there are essentially static columns of microwave energy inside the cabinet itself.
Do drawer microwaves have turntables?
No Turntable Function
Microwave drawers do not have turntables because the magnetrons are located on the top of the appliance, instead of on the sides like on a countertop or over-the-range microwave oven. What is a magnetron?
Does a microwave still work if it doesn’t spin?
The spinning wheel of the microwave has nothing to do with the waves “canceling out”. It is about even cooking. When you use older microwaves without a spin table you either move the food manually every so often, stir the food, or deal with uneven cooking.
How do microwaves without turntables work?
MIcrowaves with turntable and microwaves without turntable both have the rotating motor inside the appliance. The rotating motor of a microwave with turntable drives the glass plate, while the rotating motor of a microwave without turntable drives the stirring blades hidden under the flatbed.
How do you test a microwave turntable motor?
First, check whether the turntable motor is receiving the proper voltage from the control board. To do this, connect a volt meter across the two terminals of the motor and switch on the microwave(WARNING: WIRES WILL BE LIVE AND DANGEROUS. DO NOT ATTEMPT WITHOUT PROPER TRAINING).
