Display Module - Electrolux RM 4185 Service Instruction

3.3 Display Module

The display module is located on the control frontplate of the AES II refrigerator.
A
A Power switch
B AES operation indicator
C Low voltage LED
D Sensor for temperature setting
E LEDs for displaying the selected temperature setting
You must operate the power switch (A) to turn the device on.
The AES function LED (B) then lights up green, and the middle LED (E) lights up yellow to display
the selected temperature setting.
You can use the momentary-contact pushbutton for temperature selection (D) to change the refri-
gerator section temperature setting. The low voltage LED (C) lights up yellow if the refrigerator
has selected gas operation to maintain the refrigerating capacity due to low voltage in an electri-
cal supply source (230 V or 12 V).
If there is a fault during gas operation (gas couldn't be lit, gas container empty, etc.), the AES
LED (B) flashes red. In this case, the device does not continue to cool. You must eliminate the
gas fault and start the refrigerator again. (Use the power switch to switch the refrigerator off and
on again.)
Important:: If there is a fault during gas operation and you don't notice it before the refrigerator
changes to 230 V, for example, due to a priority change, the AES LED (B) again changes to
green until the cooling function has been established again. However, the next time it wants to
change to gas operation, the fault is displayed again, and gas operation is not started. The rea-
son is that there are legal regulations that do not permit the device to carry out an automatic
reset. If you have a gas fault displayed by a red flashing AES LED (B), you absolutely must
acknowledge this gas fault by using the power switch to switch the device off and on again.
