We chose to stick with the same brand (Whirlpool) because the space cut out of the counter was the same exact dimensions. Can you see all the little particles and spots that collect on the surface:
It was a fairly simple process of disconnecting the gas, unplugging the cooktop, and lifting it out. My husband cleaned the counter around the opening and put down new foam tape to seal the edges. We placed the new cooktop in the opening.
Doesn't it look so much nicer? It matches the rest of the kitchen and gives me a flat surface to place pans when I take them out of the oven. I am one happy cook today!
