More glass, more power: the CIT365BB stretches to 36 inches with five elements and a Triple Zone Element, and its 10,800 watts is well above what the 30-inch CIT models draw. It needs a 50-amp, 208-240V circuit, and it is run from a Multitouch+ panel with PowerBoost available on every zone.
That electrical demand changes the order of our checks. If the whole cooktop is dead, the dedicated breaker comes before anything inside the unit, because a tripped or weak circuit mimics an internal failure. A partial heating pattern on the large merged zone gets a different test: confirm the pan covers the whole area.
When a single zone loses PowerBoost while the others still work, the finding narrows quickly to that zone’s coil or driver electronics. We confirm with the other zones as a reference before suggesting a part.
At the dedicated 50-amp breaker. This cooktop draws heavily, and a tripped or failing breaker can look just like an internal failure, so we rule it out before opening the unit.
If the pan does not cover the merged area, only part of it heats. Moving the pan to span the entire zone, or switching to a pan sized for it, normally corrects that.
With the other zones healthy, the control panel and supply are fine. The trouble most likely sits in that zone's coil or its driver board, which we test on its own.
