If you've got a newer home, there's most likely a microwave in the kitchen.  But builders love to mount microwaves above the stove or high on a wall. These ovens are hard to reach. And they can be a hazard. They force you to reach above your head to get hot foods out of the oven. Lose your balance and you could burn yourself, break a dish, or both.

Microwave ovens should be no higher than 48 inches above the floor. Is your microwave mounted on the wall? Then put a shelf under the oven where you can rest hot foods after they finish cooking. Better yet, put your microwave on a counter and leave plenty of room for place hot dishes.
