I. Brief introduction
ERL-4796S is a fridge-freezer combination controlled by just one control system. The
microcomputer system can control the temperature in the fridge, freezer and wine
compartment respectively.
Temperature of the frost-free freezer can be adjusted between –15℃and –21℃. It is for
storage of fresh, cooked or frozen foods and ice-making.
Temperature of the static wine compartment can be adjusted between +6℃and +14℃.
There is an axial fan inside to make the temperature even in the compartment. This
compartment is used to store wine and other drinks.
Temperature of the static fridge can be adjusted between +2℃and +8℃. There is an
axial fan inside to make the temperature even. This compartment is used to store foods
for short periods.

V. Components and description
1） Display board
A. For functions and operation of the display board please refer to the User Manual.
B. Functions of Key combination
a. Press SETTING and ▽buttons simultaneously within 1 minute when the power is
switched on ---- to activate Device Testing function
b.Press Setting, TEMP, △and ▽buttons simultaneously within 1 minute when the
power is switched on ---- to activate Demo function
c. Press TEMP and △simultaneously within 1 minute when the power is switched on
---- to activate Quality Testing function
d. Press SETTING, △and ▽buttons simultaneously at any time ---- to activate
Forced defrosting function
2）Power board: with power failure memory function and program resumption function.
Before any setting is done when the refrigerator is turned on, the default temperature and
itsrangeisasfollows:
default range
Fridge +5℃2℃~ 8℃
Wine
compartment
+12℃6℃~ 14℃
freezer -18℃-15℃~ -21℃
Electromagnetic valve: the electromagnetic valve is made by AWECO
from Germany and is an 2-way 3-pass pulse electromagnetic valve.
Both valves are dual stable state valves controlled by AC current. The
flow direction of the electromagnetic valve is controlled by 4

The working voltage of the valves is 175V~264V
When the ambient temperature is 20~25℃, the numerical value of the resistance of the
coil is 2795Ω± 10%.
Please make sure the conduits of the valves are correctly welded,
The capillary tube with red mark is for the freezer system.
The capillary tube with black mark is for the wine compartment system.
Temperature sensor: There are six sensors on the three compartment inner liners and
evaporators respectively.
Their value of resistance at different temperature are the following:
sensor temp resistance
+20℃~ 4 KΩ
+10℃~ 5.4 KΩ
+5℃~ 6.8 KΩ
-20℃~ 25 KΩ
-30℃~ 47 KΩ

）Centrifugal fan: There is an DC centrifugal fan in the frost-free freezer. There is
also an relatively smaller DC centrifugal fan at the top of which is the static wine
compartment and fridge, more energy saving and of lower noise compared with regular

fans and keeps a balanced temperature among each compartment with quick temperature
decrease.
VI. Malfunction and remedy
1)、“--” displayed for the Wine Compartment
Note:
When the ambient temperature is close to or below 0°C, there is no problem with the
appliance. Repair according to item 14 is required only when the food is frozen and
“—”
is displayed. Temperature of the wine compartment should only be displayed as above
0°C.
2) “C1 ”displayed as the wine compartment temperature
Note:
Temperature sensed by the wine compartment sensor is beyond controllable range
Attention:
If such malfunction occurs, the appliance will be running in a special safe mode. The
refrigeration function of the appliance is protected but temperature will not be displayed.
Check if the ambient temperature is above 45°C or not and if the appliance is just
switched on or not. If it is just switched on, check the temperature display after the
appliance has run for 1 hour.
Cause A(most likely): sensor plug does not contact well with the power board
Remedy: check, clean or repair the plug and/or socket
Cause B: the wine compartment sensor is broken
Remedy: check the resistance value of the sensor and compare it to the value in the
diagram. If the actual resistance value is not in the prescribed range, repair the sensor.
3) “C2 ”displayed as the wine compartment temperature
Note:
Temperature sensed by the wine compartment and its evaporator sensors is beyond
controllable range
注：Attention:
If such malfunction occurs, the appliance will be running in a special safe mode. The
refrigeration function of the appliance is protected but temperature will not be displayed.
Check if the ambient temperature is above 45°C or not and if the appliance is just
switched on or not. If it is just switched on, check the temperature display after the
appliance has run for 1 hour.
