Oven began heating irratically and got worse.

Funny, I suppose. We decided to buy a new stove given the old age of the old one. Problem is, on delivery day it wasn't delivered and we discovered that there wasn't even one in the warehouse. At that point we got ticked and decided to look into the problem. The website led us right to the problem. We ordered, the part arrived the next day and the replacement was simple. Just unscrew the holder inside the over, unplug the old element and plug in the new. I needed needle nose pliers because one of the wires slipped behind the insulation. We also bought a thermometer and found that the calabration was right on the money. Happy campers... we saved $400.
