2. FUNCTION OF CENTER THERMOSTAT AND THERMALFUSE
C. Thermal Fuse
The thermal fuse is used to open the circuit to the cooking heater when the temperature has gone unusually high. This happens in cases such as incomplete contact between the heater and pan or if the switch buttons is forced to stay on keeping the heater energized abnormally.
This fuse is not a resetting device and must be replaced after openning.
Whenever replacing the fuse make sure the protective cover is placed over all exposed wiring.
