6 inches of clearance between any walls and the microwave so the microwave door can open fully. Check your manufacturer's instructions to ensure you have the right amount of ventilation space around the microwave. Built-in microwaves usually require professional installation.
A well-designed microwave will need 3” of clearance at the top and the sides, with at least 1” at the rear. In other words, if you are asking 'does a microwave need space around it? ' the answer is yes. It ensures the right level of airflow and protects the appliance.
A Microwave Against a Wall Is a Bad Idea
Microwave ovens need lots of space around them, especially because this appliance has only one door. “If you put [the microwave] against a wall, both the door of the microwave and your wall can get damaged over time,” Daniel says.
3" of clearance on both sides and the top. 1" clearance in the rear. The front edge of the microwave (measured at door) should sit at least 3" or more back on the counter or shelf to avoid accidental tipping. If located on the counter near a range, we recommend locating it at least 2 ft away.
Since microwaves generate high amounts of heat, it's important to use them safely to prevent overheating and potential fire hazards. If a microwave isn't properly vented, it can overheat or even fuse together parts of it, causing a potential fire and/or injury.
Yes, built-in microwaves require adequate ventilation. The amount of cabinet depth required for proper ventilation can vary by model, but is typically about 15–22 inches. Not sure which microwave you should buy for your kitchen?
Those features greatly limit exposure to levels of radiation that are already low. And since the radiation levels drop sharply with increasing distance, the levels two feet away are about one-hundredth the amount at two inches. Proximity to a microwave oven is not dangerous.
Trudi most often suggests putting the microwave under the counter, often on the end of the island to free up space in upper kitchen cabinets. Building your microwave into the cabinetry below your countertop means it's at a great height for kids warming up snacks and keeps it out of the main kitchen flow.
To help dissipate the heat it is recommended that when installing a microwave into a cabinet there needs to be enough space to allow heat to flow away from the microwave. It is recommended to have a gap of about 50mm around all sides of the microwave.
And while many bloggers will advise you to install a microwave in your kitchen cabinets, we strongly advise against it. A microwave oven, designed exclusively for a kitchen countertop, has vents that are built into the back of the microwave.

Instead of placing food in the center, spread it in a circle around the outer edge of the container or plate. The more you spread it out, the better. This makes it easier for the microwaves to reach in and create enough friction to heat the food evenly.
As a rule of thumb, a wall oven requires around 3 inches of room in between your cabinet walls. This gap will enable you to install virtually any standard oven housing unit. It will also help shield the surrounding cabinetry from the oven's heat.
Some over-the-range microwaves have exhaust fans that vent kitchen air out of the house through ductwork in the wall. Some don't and instead filter, then push it back out into the kitchen. Many will come with the ability to do either, so you must choose which one and set it up before installing.

Countertop microwave ovens have vents on the sides, bottom, or both to keep them cool while the magnetron generates heat. Therefore, it is completely normal for your countertop microwave to emit warm air, given that it is from the vents.
Although heat is produced directly in the food, microwaves do not cook, as is commonly believed, from the "inside out". Actually, microwaves penetrate foodstuffs to a depth of about 2.5 to 3.8 centimetres (or 1 to 1.5 inches).
Smoke, sparks, and burning smells.
These are signs of a serious and urgent problem. Stop what you're doing, and turn off and unplug the microwave immediately. There's no going back if you see smoke or sparks, or smell something burning. Your microwave is failing, and it's time for a replacement.
