Product review (5 stars): Works fine, easy install.
Replaced igniter in lower oven of KitchenAid gas range.  Oven would not heat every time and when it would heat the stable temperature was significantly different than the setting - usually much lower.  Replaced the igniter and the oven now heats reliably.

One "other" is that a Coorstek item arrived, not a Whirlpool.  It works fine, fits fine.  However, I had the range professionally serviced one year ago (still under extended warranty then) and the tech replaced igniters in both ovens with Coorstek units.  Both of these units require replacement at the one year point.  I'm expecting this igniter I just installed will perform similarly and I'll be back in the market for an igniter in approximately 12 months...
