KitchenAid KECC607B Cooktop Service

One cold zone among working ones is the classic KECC607B call. Because each zone is wired through its own switch, we can narrow the search quickly: switch, terminal block, element, in that order, with a meter at each step. The cooktop is sold as KECC607BBL and KECC607BSS.
Its opposite, a zone that glows at full heat whatever the knob says, belongs to the switch as well. We pull the knob, test, and replace. A chipped or cracked surface is a separate concern; we inspect the glass under a bright light, because liquid reaching the elements below is more dangerous than the crack looks.
Where a touch panel is fitted and hesitates, a dry wipe and a breaker reset come first, then a connector check. You approve a written price before we start, and a 30-day workmanship warranty stands behind the job.
Most often that zone's switch, a terminal connection, or the element itself. We measure all three in order and replace only the one that fails, which keeps the invoice proportional to the problem.
The infinite switch has probably welded closed, so the element gets full power. Shut off the breaker, let the zone cool, and call us. We confirm the diagnosis with a meter.
We look across the surface with a bright light at a low angle, which shows hairline cracks, then check around each zone edge for chips. Damage near an element gets priority.
