Over time, oven door panel glass builds up residue and becomes opaque, making it difficult to see inside the oven when cooking. In some cases, the glass breaks or becomes cracked. When this occurs, you should replace the oven door glass to keep the appliance working properly and not waste electricity or gas through energy seepage. Most oven door panels are easy to remove and only require a few tools.
Turn off power to the oven by turning off the propane gas source or the electrical breaker dedicated to the oven. If you have used it recently, allow the oven to cool to room temperature.
Open the oven door and rotate the lock levers to unlock the hinges. If your oven is not equipped with lock levers on the hinges, open the door half way and place nails in the holes located in the middle of the hinges.
Grab each door side and pull up firmly to disengage each hinge and remove the door from the oven. Place the door panel on a table or bench with the exterior facing down. Unscrew each screw at the top interior side of the oven door panel, then remove the screws located on the door panel's bottom edge.
Lift the inner oven door panel away from the outer door panel to expose the glass to clean it.
