8.7 Adjust internal temperature correlation
Purpose: To adjust the internal temperature calibration so that the display temperature matches the
temperature at the base of the fridge.
This adjustment should only be necessary if the thermistor has been replaced.
NOTE : A display temperature within 2-3°C (3.6-5.4°F) of the actual temperature at the base
of the fridge is within normal on/off cycle temperature variation. If this is the case,
the internal temperature calibration should not be changed.
Procedure:
 Connect the fridge to 12/24V DC or 100-240V AC.
 Turn the fridge on.
 Press and hold and simultaneously until or appears on the
display. The symbols displayed will depend on whether °C or °F is selected.
 Push or to adjust the setting by one 1°C or 2°F.
 Continue pressing or until the desired adjustment is made.
NOTE: The internal temperature calibration adjustment is limited to up or down 4°C or 8°F.
 After 5 to 6 seconds of inactivity, the display will flash twice and return to displaying the current
target temperature.
 Allow the fridge to cycle on and off a few times to allow for any temperature lag.
 Check the temperature display against the temperature at the base of the cabinet.
CALIBRATION SUCCESSFUL
If the temperature display is within 2-3 °C (3.6-5.4°F) of the temperature at the base of the fridge,
return the unit to the customer and advise that this is within normal on/off cycle temperature variation.
REPEAT CALIBRATION
If the temperature display is not within 2-3 °C (3.6-5.4°F) of the temperature at the base of the fridge,
repeat the calibration procedure above.
