Electronic Control System
Temperature Log Recall Mode for All Thermistors - Begin with the unit in Diagnostic Mode (See Figure 3-72).
NOTE: If Fault Codes have been logged the control will enter Fault Code Recall Mode instead of Diagnostic Mode.
If this happens press the ALARM key to shift the electronic control system into Diagnostic Mode.
While in Diagnostic Mode, toggle through the readings using a WARMER or COLDER key until the desired thermis-
tor location code is displayed at the right side of the LCD (See Figure 3-73) (r = Refrigerator, rE = Refrigerator
Evaporator, F = Freezer, FE = Freezer Evaporator).
NOTE: If "dr", "Cn" or "A", appear, continue to toggle past these codes as it is not possible to to enter Temperature
Log Recall Mode for these thermistors.
Once the desired thermistor code is displayed, press and hold the POWER key first, then a WARMER key, then
release both keys. The LCD will now display temperature at left and the Index number at right (See Figure 3-74),
with the thermistor location code flashing at three (3) second intervals in the first index digit area ("r" = Refrigerator,
"r" then "E" = Refrigerator Evaporator, "F" = Freezer, "F" then "E" = Freezer Evaporator - See Figure 3-75 and 3-76).
Pressing the WARMER key toggles up through the indexes, from 1 to 240, while pressing the COLDER key toggles
down
NOTE: Temperature Log Recall Mode will end twenty (20) seconds after the last key stroke.
