Thermal Cut-Out Switch for Control Box
Components
The Electric 3240 ovens (both 50 Hz and 60 Hz) include a
“safety thermal cut-out switch” for your protection. This
safety related device is designed to ensure that the unit
will not overheat and damage the oven. In the unlikely
event that the oven would exceed the specified operating
temperature range, the “safety thermal cut-out switch” will
activate, thus blocking power to the unit and causing it to
turn off. The Gas 3240 ovens (both 50 Hz and 60 Hz) are not
required to have this safety feature.
