Product review (1 stars): Apparently very poor quality controls or components.
We bought this unit as an upgrade to our semi-custom home builder's model. First thing that happened is that the manifold apparently warped with early use of high heat. (i.e., the knobs were no longer perpendicular to the cook-top.) And now, if I use two burners at a time, or just the middle burner on LOW for more than 40 minutes, the ignitors start intermittently popping by themselves, as if I were holding down one of the knobs. Is it even safe to use? It's out of warranty or I'd make the builder replace it, so we're swapping it out for a GE Profile. The Kitchenaid oven is next...
