The GE Profile oven with Trivection™ technology is a microwave-assist wall oven designed to cook food up to five times faster than a traditional oven. This oven gives the user the flexibility to cook food in traditional cooking modes (bake or broil), convection modes (convection bake and convection roast) or in speedcook modes (speed bake and speed broil). This oven features easy-to-use controls that will guide you through oven operations. Bake Baking is cooking with heated air. The upper and lower elements cycle back and forth to heat the air and maintain temperature. Used for traditional baking and roasting. Best for delicate items. Broil ...

TrivectionTM Door Assembly WARNING: A microwave leakage test must be performed any time a door is removed, replaced, disassembled, or adjusted for any reason. The maximum leakage is 4 MW/cm2 (see Microwave Leakage Test). Caution: The door is very heavy. Use the correct lifting procedures. Do not lift the door by the handle. To remove the TrivectionTM door: 1. Fully open the door. 2. Remove the security screws and clips on each hinge with a Torx 20 (T20) screwdriver. 3. Pull the hinge locks down toward the door frame, to the unlocked position. (This may require a flat-blade screwdriver to start the hinge locks moving). 4. Firmly grasp ...

Note: The glass cover should be removed only when cold. Be sure to let the light cover and bulb cool completely. Do not touch a hot bulb with bare hands or a damp cloth. Replace with a new 130V halogen bulb, not to exceed 50 watts. Note: Bulbs are 50 watt in TrivectionTM oven, and 30 watts in the lower oven of double oven. To remove and replace the oven light bulb: 1. Turn the glass cover counterclockwise 1/4 turn until the tabs of the glass cover clear the grooves of the socket. 2. Using gloves or a dry cloth, remove the bulb by pulling it straight out. 3. Using gloves or a dry cloth, remove the new bulb from its packaging. Do not touch the ...

TrivectionTM Bake, Broil and Convection Elements WARNING: A microwave leakage test must be performed any time an element is removed, replaced, or adjusted for any reason. The maximum leakage is 4 MW/cm2 (see Microwave Leakage Test). Caution: Use caution when removing element from inside oven cavity due to wire harness layout. There is a possibility of the wire terminals coming loose from the element when pulling the wires through the oven cavity. Note: When reconnecting the elements, make sure the connectors are securely attached to the element terminals. The bake and broil elements have special gaskets that keep microwave energy from leakin ...
