Here is the wire that was originally feeding the hood fan and light over the stove. It is important to not cut this wire when removing the old hood. You will need a lot of slack to bring the wire up into the overhead cabinet to feed the new microwave oven.

I love the Milwaukee 2426-20 M12 Cordless Multi-Tool because of its small size and its light weight. It is the perfect power tool for tight spots like this where precision is required.

The plan is to pull the existing hood wire up into the back of the cabinet and attach an electrical box and receptacle to it so that the microwave oven can be plugged in.

This metal electrical box was mounted using one Madison Bar on the right side and a sheet metal screw on the left side. A wall stud is against the left side of the box making it ideal to attach the box. The metal box must be grounded by attaching the bare copper wire using a 10/32 screw.

Note the template tapedto the back wall. There is also another template for the top mounting holes and the cord hole. The mounting holes must be properly located.

The wall bracket that supports the rear of the microwave oven is mounted using a combination of large sheet metal screws and toggle bolts. This bracket carries most of the weight of the microwave oven.

That spot of light on the wall is coming through the hole that was drilled in the cabinet above using a hole saw so that the microwave oven electrical cord can pass through to the new electrical outlet above. Holes were also drilled for two support screws that keep the microwave oven level.

The completed ductless installation. If air ducts were connected, the work would be a little more difficult and require the skills and tools of another trade.
The completed ductless installation.  If an air duct was connected, the work would be a little more difficult and require the skills and tools of another trade.  Read the manufacturer’s installation instructions before commencing with this work.  There are height restrictions with respect to the distance from the top of the stove.  The oven must be at least a certain distance from the stove as per the instructions.  I recommend that you read the installation instructions of any appliance before you buy it.  Many manufacturers have the instructions downloadable online.
