KitchenAid KGCC706R Cooktop Service Visit

Many KGCC706R cooktops were set into islands and peninsulas, where a downdraft vent carries the cooking air away through a duct below the cabinet. That vent is also the part that gives trouble: a blower that hums but barely moves air, or a damper that sticks half shut.
On a service call we run the vent at each speed, check that the damper swings open fully, and look for grease on the blower wheel. Then we turn to the burners and controls. The rating plate on a stainless KGCC706RSS can carry the code KGCC706RSS01, which tells us which revision we are working with.
A gas valve that lets the flame die at a low setting is the other common finding, and we test it against the knob before deciding which to replace. In any gas smell situation, exit the house and call the gas utility from outside. Our estimates are written, and the repair is covered for 30 days.
Grease on the blower wheel or a damper that does not open fully are the usual reasons. We clean the wheel, test the motor, and free the damper, then run the vent to confirm the airflow.
No, it is a revision code for the KGCC706RSS version of the same base model. Knowing it helps us order the right control parts without trial and error.
The valve behind the knob may not hold a low position. We confirm that with a test before touching the knob, because replacing the wrong piece would not fix the flame.
