10.2.2 Diagnostic Mode For Service
To Select The Diagnostic Mode:
Press and hold the MODE button, then press the TEMPERATURE UP button.
The LEDs indicate the PC sensor temperature. The current PC sensor temperature is displayed in a code
form (refer Section
10.2.3).
Return to normal operation by pressing the MODE button.
CAUTION: In reading temperatures there is a need to enter the required mode when the door is first
opened, as all temperature readings are only sensor temperature/air temperatures and these will change
rapidly with the increase in air temperature as soon as the door is opened.
When in diagnostic mode, press the TEMPERATURE UP button.
1 time = FC sensor temperature. The current FC sensor temperature is displayed in a code form
(refer Section
10.2.3).
2 times = Defrost sensor temperature. The current defrost sensor temperature is displayed in a code
form (refer Section
10.2.3).
3 times = Inputs/outputs status (refer Section
10.2.4).
To exit the diagnostic mode, press the MODE button. If not terminated manually, diagnostic mode will time
out and go back to default display after 5 minutes.
NOTE: The door alarms do not operate when the appliance is in diagnostic mode.
10.2.3 Sensor Temperature Conversion
To obtain the temperature of either compartment sensor or defrost sensor:
1. Enter the diagnostic mode (refer Section
10.2.2) and scroll to the appropriate sensor temperature.
2. Add up the binary number indicated by the LED light pattern (refer diagram below).
3. Subtract 40 from the result to get the temperature.
