Oven temperature thermistor:
This sensor is used in ovens that have convection heat, The thermistor will change
resistance as the oven temperature increases. The microcontroller will compare the
voltage across the thermistor to the programmed voltage within the ROM. When the two
are equal, the convection heater will be turned off. Refer to page 42 for the proper test
procedure.
Damper switch:
This sensor monitors the position of the damper door on ovens that have the convection
cooking feature. The damper door must be closed for convection cooking and open for
the microwave mode. A signal is developed across the damper switch that is converted to
either a logic high (when the switch is open) or a logic low (when the switch is closed).
Refer to the convection oven section of this manual for more information on this
component.
