Unplug the microwave from the wall outlet inside of the cabinet above the microwave.
Ask a helper to hold on to the bottom of the microwave to keep it from falling when the screws are removed.
Unscrew each of the screws in the bottom of the kitchen cabinet. Turn each screw until it is no longer connected to the top of the microwave, then pull up on the screws and place them to the side.
Ask your helper to slightly tilt the microwave forward.
Press upward on the back of the microwave to pull the back panel of the microwave away from the wall mount's tabs.
Set the microwave aside.
