My GE XL44 gas stove all of a sudden started making a horrible sound. It is non-stop, sounds like a blender. The burners still light and the oven still warms up. The store where I purchased it says that they think the electronic timer has gone, but that the part (WB11K3) is no longer available. Any ideas if this is what could be making the noise and does anyone know if there is anyplace I can purchase either this part or an alternative that would work?
