Can You Vent An Over The Range Microwave Outside

The tools and parts were pretty cheap.

Can you vent an over the range microwave outside.

So one small home improvement that has improved my life a lot has been venting the over the range microwave fan through the exterior wall. If you have an over the range microwave it should have an exhaust fan that vents to the outdoors. Many times an over the range microwave that recirculates cooking fumes can be converted to exhaust to the outside. Microwaves are shipped from the factory to vent out the top vertically but can also be vented out the rear horizontally.

Remove the access plate on the top of the unit in order to reach the motor. Mount a tube of outdoor quality silicone sealant into a caulking gun and run a zigzag bead of silicone onto the rear facing flange of the vent cap. Over the range microwaves have a light and fan built into the bottom of the appliance. 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.

If rectangular ducting please note. 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. 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. Slide the vent cap into place and secure it with.

I already had an stud finder and the microwave exhaust duct was not expensive plus this project was fairly simple and and it has really cut down on the smoke and odor in the kitchen and in the whole house.
