THE GAS SENSOR

The gas sensor is used during the “Sensor Cook” operation of the oven. It is located above the oven and is mounted on the left side of the sensor cover. The sensor consists of two circuits housed on a small microcomputer board that is supplied with a current to keep it heated. The sensor heat conductivity will vary,

depending upon the humidity of the oven. Changing humidity conditions, due to the cook- ing process within the oven cavity, causes a difference in potential between these two cir- cuits. This difference is monitored by the mi- crocomputer during cooking, allowing the mi- crocomputer to determine the proper cook time.

NOTE: Always verify that the sensor cover is not obstructed (proper air flow is passing over the sensor), and that the fan motor is working properly, before replacing the gas sensor.

TESTING

1.Set the ohmmeter to the R x 1 scale.

2.Remove the 3-pin connector from the control circuit board and mea- sure the resistance between the:

a)Red & white wire terminals. You should measure 20 Ω @ 68˚F.

b)White & yellow wire terminals. You should measure infinity.
