•

These tests perform a check on all sensors
located throughout the unit individually.

•

Once the test for the thermistors is executed,
the instantaneous temperature of the
thermistor will be displayed in the displays.

•

If the thermistor is out of range, “ - - “ will be
displayed.

•

When reading the temp insert a decimal
between the 2 right digits.

•

The example reading below of -1077 would be
read as -10.77˚ F.

MB = Main Board, Cabinet
DB = Door Board, LH Door
