Removal and Installation of an Over-the-Oven Microwave?

I believe all you have to do is lift a little and slide it out. There might be screws holding it in - it has been quite a while since I installed mine. The width is standard, the mount might have to change with a new microwave.

Most under cabinet mirowaves are attached to a bracket attached to the wall and are supported by two bolts through the top cabinet. To remove, unplug the unit, then loosen the two top bolts (in the over head cabinet) have a helper hold the unit as the bolts are removed, as the front of the oven will drop. Together, lower the front of the oven while lifting the rear off of the wall bracket.

I have never replacecd one oven with another, so I don't know if manufacturers standardize mounts from one unit to another, but installation can be a pain. I've installed a few,and the paper templates provided never seem to line up properly for me!

Ducted venting can be another problem, but if your unit doesn't vent to the outside, don't worry about it.

Microwave are all standard width of 30" Most likely you will have to change the wall mount and drill new holes in the upper cabinet for mounting holes and the cord. To remove the old one there are usually 2 screws in the upper cabinet toward the front that hold it in place some brands have a screw in the vents above the door. Remove the screws unplug the micro and tip forward then lift off of the rear mount.

typically the bolt holes are the same. 3/8" diameter - 10 1/4" from the back wall and 13" left and right from center. The back plates are all a little different. I have hung probably around 300 microwaves

all 30" wide will fit there check the opening of your existing vent. It held only with 4-6 screws to the cabinet at the to and to the wall behind with a plate. That's all to it. Purchase a new vent to fit the new microhood. good luck
