Can All Over The Range Microwaves Vent Outside

Microwaves that vent to the outside force the air through duct work to the outdoors.

Can all over the range microwaves vent outside.

Microwaves over the range otr typically vent in two different ways. Over the range microwaves have a light and fan built into the bottom of the appliance. If you have an over the range microwave it should have an exhaust fan that vents to the outdoors. Microwaves are shipped from the factory to vent out the top vertically but can also be vented out the rear horizontally.

Over the range microwaves can vent to the outside or can recirculate the air. In the first example the microwave over the range otr will vent through the manufacturer installed grease or carbon filter then directly through an exhaust port that is ducted to the outside of the structure. Ultimately the goal of the vent is to pull the air from the microwave and deposit it to the outside. Typically there might be a cabinet installed over the microwave and inside that cabinet will be duct work or a soffit above the microwave or a direct wall exhaust.

For this reason vent ducts are the only choice. Remove the access plate on the top of the unit in order to reach the motor. If rectangular ducting please note. Many times an over the range microwave that recirculates cooking fumes can be converted to exhaust to the outside.

All over the range spacemaker microwaves can be vented to the outside using an equivalent total of 140 feet of rigid 3 1 4 x 10 rectangular or rigid 6 round ducting. When a microwave is replacing a standard range hood it is usually best to use the existing venting method.
