Product review (5 stars): It works in a Kitchenaid Gas Cooktop
The Whirlpool parts work in a Kitchenaid Gas Cooktop with glass surface.
I cleaned the cast iron/ceramic finish parts with ammonia (soak in 1 cup for few hours then clean in soapy water).
After drying all of the parts in front of a gas fire, I glued the rubber pads in with Permatex 82180 Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker, 3.35 oz. Tube, also available on Amazon. Used a toothpick to apply the RTV to each hole.
No problems.
Ordered from Reliable Retailer.
