How to install a KitchenAid built-in microwave: a step by step guide
DISCLAIMER: This video is intended only to supplement the written installation instructions that accompanied your product, not to replace those installation instructions. The written installation instructions should be read and available to you before you attempt to install the product. If you have any questions about the instructions in this video, or are not comfortable performing the installation demonstrated, contact the manufacturer's customer service.
Before you begin the microwave oven installation, refer to the installation manual for a list of recommended tools and parts you may need.
- Phillips screwdriver
- Flat-blade screwdriver
- Measuring tape
- Drill (for wall cabinet installations)
- 1/8" (3mm) drill bit (for wall cabinet installations)
- 1" (2.5cm) drill bit (for wall cabinet installations)
Step 1: Measuring the cabinet opening
For proper installation, the cabinet opening will need to be 28 ½ inches wide, with a recommended height of 17 ⅝ inches. A minimum depth of 21 ⅞ inches is required, along with 2 and 3/16 inches of clearance above the opening and a 1 inch clearance below.
Step 2: Confirming the electrical supply
The electrical supply for the appliance must be 240V at 60Hz. A dedicated circuit is required.
Step 3: Assembling and installing the spacer kit
First, assemble and install the provided spacer kit, if applicable. With the flange facing outward, align a spacer bar on the bottom trim and secure it with two 3/8 inch washer screws. Do the same to align and secure the opposite spacer bar. Now center the spacer assembly against the lower front edge of the cabinet opening. Using a 1/8 inch diameter drill bit, drill through the mounting holes in the spacer bars to create pilot holes. Use a Phillips head screwdriver to thread and tighten the 4 ¾ inch flathead screws to secure the spacer assembly. Avoid overtightening the screws.
Step 4: Unpacking and moving your built-in microwave oven
WARNING: Excessive Weight Hazard. Use two or more people to move and install the microwave oven. Failure to do so can result in back or other injury.
Remove any packaging materials from the microwave oven, as well as the glass tray, support and any other accessories, if applicable. Resting the appliance on a piece of cardboard, have an assistant help you to set the microwave on a cart or countertop adjacent to the cabinet opening.
Step 5: Connecting the microwave wiring
WARNING: Electrical shock hazard. Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock.
Before making any electrical connections, make sure the power supply to the junction box is turned off. If necessary, remove the junction box cover. Use a UL listed or CSA approved half inch diameter conduit connector to connect the flexible cable conduit from the microwave oven to the junction box. Tighten the screw or screws to secure the conduit.
Now join the black wires together and secure them using an approved, UL listed wire nut. Do the same to secure the two red wires together, and the two white wires. Finally, join the green or bare grounding wire or wires to the bare grounding wire from the microwave oven and secure them with a wire nut. With all of the wires positioned inside the junction box, replace and secure the cover.
Step 6: Installing your built-in microwave
Using two or more people, align the microwave oven on the spacer bars, if applicable. Open the microwave oven door and push against the front frame of the oven to fully insert the appliance into the cabinet. Confirm the appliance is centered, then use a 1/8 inch diameter drill bit to drill pilot holes, using the holes in the side mounting brackets as templates. Align the plastic washers with the holes in the mounting brackets, then thread and tighten the two 3/4 inch flathead screws to secure the appliance to the cabinet. Avoid overtightening.
Replace the glass tray support and the tray as well. Turn the power supply back on, and the microwave oven should be ready for use.
