Note: If one or more functions do not work and no
apparent damage is present, the cause can be an
excessive fl at-bottom drop of the packaged unit

the heat shield mounting tabs. This would cause
improper spacing between the underside of the
glass top and the capacitive switches on the
module, rendering the switches inoperative.
