I was ready to replace the entire unit (cracked glass top and a non-working burner) but with a bit a research and patience I realized that it was an easy DIY repair job. In order to replace the burner I had to remove the glass top, which required lifting the unit off the counter (need to disconnect the downdraft duct) and unscrewing the top's frame (10 screws). Once the top is removed the heating elements are exposed.To replace the burnt-out element I had to disconnect the wires (make sure you know which is which to reconnect the new element) popped it out, and connected the new one. Very simple procedure. Once the new element was in, I installed a new glass top and placed the unit back in the counter (you will need a roll of foil tape for the duct work and a strip of about one yard of foam tape for the new glass top).
Bottom line: I SAVED about $1200 in approx 20 minutes! And have the satisfaction of a successful DYI project!
