detects temperature higher than limit value.

defaults to high speed. When cavity

temperature lowers to 212°F/100°C, heating

will resume and error will be cleared. (If self-

clean was running, it will be disabled until a

control reset is performed.)

interface and control module.

and control module or TCM and user interface.
