The trim vent piece on the door of my oven was damaged when I used the "self clean" on it. A towel hanging on the handle started smoldering and stuck to it leaving a bad burn mark.

I first used an Allen wrench to unscrew the two screws that held the back of the oven door to the front. Then when I got that apart it revealed about 12 other screws that held the handle and trim vent piece on together. I unscrewed each of those with the socket set (it took me a while to find the exact size I needed). I took off the handle and trim piece and slid the new piece onto the slots, put the handle back on and then worked in reverse order to screw all the screws back into their places. The only problem was that I didn't realize some of the screws were a bit longer than others and by the time I took them all off and went to screw them back in, I realized that I hadn't noticed which places needed the longer ones and which had the shorter ones. So if you are doing this repair note that not all the screws are the same and you will want to remember which ones go where before putting them in a big pile like I did. After all the screws where in place I pushed the back of the oven door together with the front and used the Allen wrench again to screw them tightly together. Pretty easy overall- at least for a housewife!!
