Not sure where to find model number. Glow bar number is WB13K0021, if that helps. Older stove - used. All 4 burners work fine; but, oven would not light so I replaced the glow bar. As soon as I plugged in new glow bar it lit up and stayed lit even though temp dial was turned off. Any suggestion on what it might be? And where would I find video on how to replace any new parts ? Also where is the best place to purchase it and would a generic part work ?
