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.
