Product review (5 stars): Worked Perfectly for my Tappan Oven
My Tappan 318200753 was having an issue where it wouldn't stay hot.  It would heat up to the initial temperature just fine, but wouldn't cycle the heat to stay hot enough.  The flames just wouldn't come back on.

After some research, it was apparent that the ignitor was the likely culprit.

After a pretty straightforward 20 minute installation of this new ignitor, it works like a charm.
