I found some websites that sold replacement bezels but only for the burners, the oven temperature knob was sold out everywhere I looked. I could use the burners without knowing the settings, but the oven was another story.
I had to find a way to number the oven and I wanted the burner knobs to match. The replacements all looked bright white and would really stand out next to the old, yellowed plastic of the knobs and the other bezels. My solution was to make my own sticker labels to cover the old bezels.
Step 1: Acquire Template Images
There are a number of websites that sell appliance parts online. They all seem to use the same images to show their stock. If you can find images of the exact item you need, right click on it and save it to your computer.
The grid in the background is very helpful. Somewhere on the image it usually tells you the scale (ex. Squares are 1" x 1"). Estimate the length and width of the image and resize it in a photo editor using inches as the units instead of pixels. Convert the image to grayscale and adjust the brightness and contrast all the way up. You want the white parts of the image to be completely white while the black parts are still sharp and completely black. Crop the images down to just what you need to print.
Print these new images on a laser printer. Inkjet printers will not work.
Step 2: Cutting
Clear Packing tape
Cut up the printout. Remove anything but the numbers, symbols and letters. Any shadowing from the form of the knob should be cut out.
Step 3: Taping
Wet the tape under hot water. Let the water soak into the paper and soften it up. Wet the tape again and let it stand aside again. When the paper is saturated, hold it under the hot water and the paper should just peel away. The paper around the letters is going to stick a little more and needs to be gently rubbed away. The fibers of the paper will stick the laser toner, but will eventually rub off completely. Let the tape dry and it will be just as sticky as it was before the paper.
(The L on the "Lite" didn't come out on this one, but I didn't notice until after I was done. Looks like i will have to redo this one.)
Step 4: Sticking
Use the hobby knife to cut away the excess packing tape. If there is a bevel or a curve around the edge, you may want to cut off the tape at the edge of the face so you get a clean edge.
In the last picture you can see another label I made for the oven knob. They worked perfectly! Now I just have to finish the rest of them.
