My light switch housing broke, making the oven light stay on all the time.

Most important: Unplug or turn off the breaker before beginning! (I briefly saw sparks as I removed the old switch.) Look at the replacement switch. The springs on the sides hold the switch in, which means you have to press in these springs to get the old switch out. I slipped a small screwdriver in on the side while I pulled with a small pair of pliers. It's tricky, but it will come out. Once you have the switch out, just unplug the wire in the back, making sure it doesn't fall back in the hole before you get the new switch on. Then, just push the new switch into the hole in the stove and you're done.
