resistance of the sensor increases. The
resistance of the sensor at 350°F is approxi-
mately 1654 ohms. The electronic control
monitors the resistance value of the sensor
and cycles the oven heating elements off.
As the temperature in the oven decreases,
the resistance of the sensor decreases. At a
predetermined temperature setting, the
electronic control will initiate another heat-
ing cycle in the oven elements. See oven
sensor chart at right for resistance values.

FAULT CODES
There are built-in fault codes to assist the technician in diagnosis of the control system. Any
time the control senses an error in the system, the control will beep at s 1 second interval
until the ON/OFF key is pressed.
