Remove a GE Spacemaker
The GE Spacemaker series of microwave ovens are designed to be installed above an oven range, freeing up counter space in your kitchen. Some of these Spacemaker models are connected to an outside venting system to carry kitchen vapor and odors outside. Other Spacemaker models utilize a ductless system to do this. Removing a GE Spacemaker microwave oven isn't a difficult task, but, because of the size of some of the oven models, it is a two-man operation. Have a question?

Things You'll Need

• Assistant
• Sharp knife

• Phillips screwdriver

Instructions

1. • 1 Open the cabinet above where the Spacemaker microwave oven is installed. If you see a vent in the cabinet leading to the Spacemaker oven below, your Spacemaker is vented. This vent needs to be disconnected before continuing with removal. Disconnect the vent either by loosening the duct clamps or by cutting the duct tape away with a sharp knife. Pull the vent out of the top of the oven.
     
   • 2 Have an assistant support the oven from below. Loosen the mounting screws connected to the Spacemaker through the cabinet bottom. Loosen the screws by turning counterclockwise with the Phillips screwdriver.
     
   • 3 Unplug the Spacemaker from the socket in the cabinet.
     
   • 4 Continue loosening the screws while your assistant holds the oven in place. Once the screws are removed, have your assistant slowly lower the Spacemaker down by lowering the front face at a 45-degree angle.
     
   • 5 Feed the power cable for the Spacemaker through the hole in the bottom in the supporting cabinet.
     
   • 6 Help your assistant slowly pull the Spacemaker forward and out of the mounting brackets on the rear wall. Once the Spacemaker is cleared of the mounting cabinet and rear wall, set it down.
     
   • 7 Remove the mounting bracket from the rear wall by loosening the screws.

If it is not mounted above, it is most likely attached to a mounting bracket behind the microwave. I would start with removing the vent cover (if there is one) and check for access to screws or bolts on the back side of the microwave. Make sure that you have a friend helping!

You are going to need the installation template and the mounting bracket. You should be able to get these from the original manufacturer.

HI,

Frigidaire makes several over-the-range microwave models that are all installed in the same manner. To install correctly, you must have at least 45 1/2 inches from the bottom of the top cabinet to the cooking surface of the stove to provide enough clearance for the microwave. The top cabinet must also be at least 30 inches wide and 12 inches deep. Find someone to help you, then follow the steps below to install your Frigidaire microwave.

Things You'll Need:

• Stud finder or hammer
• Screwdriver
• Drill

Instructions

Pull your range away from the wall so you can work comfortably. If this is not possible, cover it with a drop cloth. Find and mark the locations of the studs in the wall behind the range. They will be either 16 or 24 inches apart.

Follow the instructions on the wall template to mark the location of the mounting bracket and the four anchor holes on the wall and the bottom of the cabinet. Drill the anchor holes. Follow the instructions on the top cabinet template to mark and drill the two holes in the bottom of the cabinet.

Attach the mounting bracket to the wall studs using the six wood screws included with your microwave. Screw the toggle nuts onto the toggle bolts and push one through each of the four drilled holes. Screw each toggle bolt until the nut is snug against the inside of the wall.
Pick up the oven with your helper. Plug the oven into the outlet and slide the oven onto the mounting bracket arms. Push the oven back against the wall. Tighten the two screws on the microwave faceplate to fasten the microwave to the mounting bracket arms.
Attach the louver to the top of the microwave with the three provided screws. Insert the two top cabinet screws and washers from the top cabinet into the microwave and fasten tightly.

Take care.

you can not get a plate . only plate that mounts it is the one that came with it . now I did this with my own sharp and this wil work with any . cut the wall benind same size of micro / this will let you slide it into the wall almost 3 in . giving you more room to cook and work on range top. she loved this . then attach the front by the bolts from the top or screw/s to the side of both .. makes a neet install ..****/ feed back pls .. dont forget the power goes in the top ,,

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

You can find handy exploded views and order parts by model number here.

They used to sell them at sears. Its a common duct item for vents. Try home Depot.

I would suggest a home improvement store such as Builder's Square, Lowe's, Home Depot, etc.

Otherwise, maybe local heating and air conditioning companies can point you to a source.
