Reviewed a couple of YouTube videos. Searched for online replacement part. Found AppliancePartsPros and ordered OEM Whirlpool oven ignitor. Placed order for this part on a Monday afternoon and the part arrived on my door step on Tuesday afternoon ! That was amazing.
I then followed the YouTube video instructions. The stove unit in the video was exactly like ours which made it very easy. Removed old ignitor, replaced new. One of the small bolts holding the ignitor had been stripped from the factory which made removing it difficult and replacing it even more fun. Tested, all was good, ignitor glowed and then the gas flow began and oven heated perfectly. Wife was excited she could clean behind the stove, bonus points :)
