How to tell if your microwave is vented outside?

A duct is commonly placed above the microwave to prevent any possible harmful fumes from getting into your food.

However, there are times when this exhaust chute isn’t connected to the outside of your home.

If that’s the case, it most likely has intake vents on the bottom of it, which are most often connected to the back wall behind it rather than being vented through the cabinet above.

Does a microwave need ventilation?

Yes, microwave ovens need ventilation. However, the venting needs differ according to the manufacturer and design. Proper clearance and ventilation are needed for efficient operation and safety reasons.

Adequate external ventilation may be necessary for some microwave ovens that do not incorporate their own ventilation systems.

What clearance is required for microwaves?

Make sure there’s between 3 and 4 inches of space on all sides and the top. Make sure there’s at least 1 inch of room behind the unit and that it sits back from the front edge by another 2 inches.

Put the microwave on a sturdy counter; we recommend at least 2 feet away from a range if you are putting it on a solid surface that is not adjustable.
