Product review (5 stars): Oven fix
The Whirlpool range had been doing some strange things just before the oven stopped lighting.  The Problem was researched on the internet, and my guess was confirmed.  Ordered the part (Whirlpool 4342528 Oven Ignitor) and was happy it was an exact replacement.  Changing part was easy and oven works like new.  Locally the part would have cost me double.
