Our old Holiday stove was in OK shape, if you don't mind some rat feces and a broken knob. First thing was to disassemble and clean everything.
The left knob stop was broken, so you never knew if it was on or off. I can't be sure kids playing house didn't twist it too hard, but the fix was pretty easy. Where the stop pin was broken, we just pushed a little more of the pin out through the shaft and it still had at least half inside.
