Venting Microwave Through Wall Stud In Way

My microwave oven is mounted to an exterior wall above the stove.

Venting microwave through wall stud in way.

Get a dryer vent going from outside to inside of the house. If you don t want to cut the stud install 2 rectangular ducts on each side of the stud and split the original duct into two. Basically tear down the wall to install a header saddle jack studs etc. It appears when this house was built provision was made for venting out the rear of the microwave into the standard 2 4 wall up the cavity inside the wall then up through duct work in the attic through the roof.

I fixed it so that now it vents the kitchen smoke and odors through the wall and outside. If the two rectangular ducts have a combined area greater than that circular one you wont have issues with flow restriction. A stud in a wall supporting or otherwise can be cut and boxed. Total distance is about a foot performance will be barely compromised.

Think of an turning into a line with a box in the middle. It is designed to work like a hood. First double check that your floor joists are lined up well enough that you can get a 10 duct through the floor where you need it. The manual for the microwave says to absolutely not use flexible ducting.

Buy the sheet metal boot that converts from 3x10 rectangle on the top of the otr microwave to 5 or 6 inch round duct. If a floor joist or a beam is massively in the way you ll need some custom ducting or cancel the job entirely. Studs run vertically through a wall. This usually takes two people.

Connect it all with a piece of flexible dryer vent hose. Re install trim or siding. Your proposed opening for the exhaust is pretty close to the underside of that cabinet and the header must go above the exhaust vent. Option 1 results in a very twisty exhaust path while option 2 is obviously a ton of work.

You will have to remove quite a bit of drywall and most likely that wall cabinet directly above the oven. Just use flexible dryer vent and be done. I saw this done on this old house when they installed a new microwave hood on an outside wall. Install exterior vent hood utilizing proper exterior installation techniques applicable to your siding material.

Photo of unit installed it was heavy and bulky. But the builder just left the microwave s fan blowing back into the kitchen. From microwave up into the cabinet is what you have now. Sacrifice the cabinet above the stove by snaking an exhaust duct up from the hood over to one side of the stud and then through the wall.

I d cut a generous square at the bottom of the wall so you can cut out the plate in the stud bay. Can anyone think of any other options. Basically i would start by breaking out the drywall around the proposed opening and that stud in the middle. Line up microwave to duct and connect by placing it on the wall bracket or connecting bolts above.
