I have a whirlpool gas oven that is not heating up when I turn on the oven... I seen info regarding this saying it may be the fuse and that it's a part that is inexpensive but hard to get to. I was wondering if removing the oven from the cabinet is something a home owner could attempt or should it be left to the professionals? and if by chance is there anyone that could give directions on how to do this if it's something a home owner could try
