KitchenAid KECD806R Cooktop Service Visit

The KECD806R can be found as KECD806R, KECD806RSS and KECD806RWW, and as a current model it comes up often. The most disruptive failure is the stuck switch that leaves a zone at full heat: shut the breaker off at once, and we will test the switch and replace it. Other zones are rarely affected.
Glass cracks come second. We study the surface from several angles because a hairline crack can hide against the pattern, and any crack takes the cooktop out of use until repaired.
For versions with a touch panel, dampness is the usual cause of erratic behavior; dry it and reset the breaker. On a gas configuration, a clicking igniter that will not stop is wet or dirty, and a gas smell means going outside and calling the utility. Pricing is given in writing, and a 30-day warranty follows the repair.
Switch the cooktop's breaker off immediately and keep it off. A stuck infinite switch is the likely cause. We test it with a meter and replace it, leaving working zones as they are.
Look across the surface at a low angle under a bright light. A line that catches the light is a crack. Stop using the cooktop and let us confirm and quote the repair in writing.
Water or grease on the panel can register as touches. Wipe it fully dry and reset the power. If it repeats, we test the panel connector and the ground.
Book in about a minute, or call the desk. Same-day windows inside the Loop on most days, next-day across the rest of Houston.
