Liebherr ICBN 3366 - nie trzyma temperatury

Nie próbowałem jeszcze odmrażać, ale zrobię to jak tylko będę mógł. Czy sprawdzałeś temperatury z czujników z menu serwisowego? Niestety nie mogłem nigdzie znaleźć manuala serwisowego do tego konkretnego modelu, także sugeruje się manualami serwisowymi od innych modeli. Czy oznaczenia czujników są takie same? Ciężko powiedzieć, teoretycznie powinny być. Odczyty z mojej lodówki: E0 BioFresh air sensor +10°C E1 Refrigerator compartment air sensor +10°C E2 Refrigerator compartment evaporator sensor +9°C E3 Freezer compartment air sensor -20°C E4 Freezer compartment evaporator sensor -46°C E7 Ambient air sensor +36°C E1 IceMaker air sensor -6°C Panel: +5°C -18°C (opisy odczytów pochodzą z manuali serwisowych innych lodówek Liebherr, także nie gwarantuje, że muszą się zgadzać) Jak widać, to co wyświetla panel nie zgadza się z tym co jest odczytywane z czujników. Gdy lodówka przestaje chłodzić czujnik E2 wskazuje zawsze ujemną temperaturę, nawet -25°C. Aby ponownie zaczęła chłodzić, należy odczekać jakiś czas lub odłączyć zasilanie (wyłączenie z przycisku na lodówce nie przywraca chłodzenia). Kostkarka nie produkuje lodu automatycznie. Przy wysterowaniu z ręki natomiast potrafi się zakręcić i uzupełnić wodę. Wrzuciłem do załącznika dwa manuale serwisowe, na których bazuje.

3.0 Description of the appliance
The CS 14../ CS 16.. is a combined refrigerator-freezer with NoFrost freezer compartment. The appliance has two
compressors.
The CS 1660 has an water filter in the refrigerator and an Icemaker in the NoFrost freezer compartment.
The refrigerator compartment has a freely suspended rear wall evaporator. The temperature is controlled using an
evaporator sensor and an air sensor.
The freezer compartment has a lamellar evaporator with integrated defrost heater and fan. Two sensors, an air
sensor and an evaporator sensor, see to the control and automatic defrosting. A safety temperature limiter
protects the appliance against excessively high temperatures during the defrosting phase.

Alarm value:

4K warmer than set value.

SuperFrost alarm value: 0°F.
Delay:

60 min.

Visual:

Flashing temperature display.

Audible:

4 beeps.

During start-up:

The temperature display flashes until the switch-off value
is reached, the audible alarm is switched OFF.

(for example with a set value of 0°F, there must be a temperature of 6°F for at
least 60 mins., then a temperature alarm is issued.)
When the defrosting phase begins, the temperature
alarm is suppressed for 1.5 hrs.
Defrosting:

ON:

- During start-up after 6
hours cumulative compressor running time.
- After a cumulative compressor running time of 12 to 24 hours
maximum, depending on the number/duration of the door
openings.
When the defrosting phase begins, the compressor and the fan are
switched OFF and the defrost heater is switched ON.

Duration:

Info:

SuperFrost:

After the end of the heating phase the compressor is switched ON
with a 10-minute delay.
If the SuperFrost function is activated during the defrosting phase,
this will not interrupt defrosting.

When:

If door is open, after 180 seconds.

Audible:

Door alarm:

The defrost heater remains switched ON until
- the freezer compartment evaporator sensor has reached 41°F or
- a max. defrosting time of 50 minutes has been reached.

3 beeps.

ON:

Freezer compartment sets itself to -40°F
(quantity-controlled, min. 30 hrs., max. 65 hrs.)
The appliance sets itself to -40°f for at least 30 hours. In the
following 35 hours cooling by 8K to the set value must have been
reached or a total time of 65 hours must have elapsed in order that
SuperFrost is automatically ended.

OFF:

The freezer compartment sets itself to the set value.

Note:

If SuperFrost is actuated during a defrosting phase, the SuperFrost
function is not performed before the defrosting phase has run.
