There is no one way to remove glass from an oven door. Because of the many different manufacturers, there are many ways in which the door attaches to the oven and many ways of disassembling the door. The door connects to the oven with two hinges toward the bottom. Most oven doors will disconnect by lifting the hinge off a bracket while others may secure with screws. To access the glass, you will need to disassemble the inner portion of the door from the outer portion.
Pull out the bottom storage drawer in the oven if you are removing the oven door from a freestanding or slide-in range oven. Lift the back of the drawer to remove it completely from the oven. Reach inside the drawer cavity and disconnect the power cord from the wall outlet. If you are working on a built-in wall oven, turn off the circuit breaker to the oven. The circuit breaker will be inside the home electrical panel.
Open the oven door halfway, if your unit is a freestanding or slide-in range oven. Locate the door hinges toward the bottom of each side of the door. If your door hinges have a plastic cover over them, remove the screw securing the cover with a Phillips-head screwdriver. On models that do not have covers, look for an empty hole on each hinge near the door. Grab the door on each side and lift up to disengage the door hinge from the oven. Pull the door away from the oven.
Open the oven door fully if you have a built-in wall oven. The hinges will have a latch securing the door hinge. Insert a flathead screwdriver between the hinge and the latch and lift the latch to unlock the hinge. Grab the oven door on both sides and close the door as far as it will shut. Lift up on the door and pull it away from the oven.
Set the door down on a flat surface with the door handle pointing to the floor. Look for screws along the side edge and bottom edge of the door that secure the inner door panel to the outer door panel. Remove the securing screws with a Phillips-head screwdriver or nut driver, depending upon the type of head on the securing screw.
Lift the inner panel away from the outer panel of the door. Some self-cleaning models may have an electrical connection between the two door sections. The wire connector is most often a white block with release tabs on the side connecting to a circuit board. Press the tabs with your fingers and pull the connector away from the circuit board.
Remove the glass from the outer panel of the oven door. Some models use screws to secure a glass frame while others use the pressure between the two door panels to hold the glass in place.
It is a good idea to have your owner's manual. Most owner's manuals will indicate how your particular door is removed from the oven.
Always disconnect power from appliances before attempting repairs.
