Product review (5 stars): Stove works now
I was skeptical that replacing the ignitor in our Magic Chef (a.k.a. Whirlpool) oven would fix the slow heating problem but I ordered this relacement ignitor and installed it and the stove is as good as new.  The installation took abou 20 minutes mainly because I had to lay on my stomach to get at the panels, etc.  The  ignitor comes with simple instructions and extra wire (in case the snap plug doesn't fit the old plug) and some insulation to stuff in the access hole.  Other than the awkward positions I had to assume the installation was smooth and the oven fired right up and reached the preset temperature in a few minutes just like it used to.  Great product and a cheap simple fix for a slow heating oven.
