2 burner valves froze before the 1 year warranty was up. GE tech fixed at no cost. A 3rd burner valve failed (froze) 8 months later and again GE is fixing it at no cost. Don't misunderstand GE has great service and is taking care of it which make me happy. But what if another goes out and then another. I feel I must pay the extended warranty in order to have piece of mind so will. It would make me feel more at ease if GE would just replace the whole unit. I am afraid this will happen again.
