How to replace Cooktop Cleaner For Ceramic Glass Surfaces. Bought replacement relay board, replaced it. Would not work, turned stove circuit breaker off then on again. Display panel showed stove was resetting waited for reset, tested the bake option twice to ascertain it was working correctly. It worked!
