Over the past 3 months inconsecutively, 3 out of 4 burners have stopped heating up. At the same time I've noticed that it's taking a long time for my oven to heat up to 350 degrees.
Are there parts available to fix this on my own? Or do I need to replace the entire cooktop?
I've been using this stove for apprx. 7 years.:confused: Thank-you.

Ceramic-glass cooktop with radiant and dual radiant surface units, electronic oven controls, self cleaning oven warm and serve drawer
