When my wife and I bought our house, this stove came with it. It is a Magic Chef model # 3187VRV and by my estimate its about 20+ years old. The knobs all worked fine, but all of the numbers were worn off.
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
If the part you are looking for has a flat area where the letters are printed, you can probably just relabel your existing piece.
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.
