One consuming device is omitted if the cancel button for the refrigerator is pressed. Due to
their low power consumption, the fans can only be checked manually. (The air current can be
heard and felt when the door is open and the door switch pressed).
9.3.2.Step 2 and 3 (a 2 or 3 flashes in LCD display)
These two steps automatically check
a)
the sensors for cross-over
b)
the two compressors for performance
c)
the magnetic valve
d)
the longfresh fan.
Step 2 longfresh compartment in sole operation (voltage applied to magnetic valve)
Step 3 longfresh compartment and freezer in operation (no voltage on magnetic valve)
Principle to a)
The evaporator sensors cool faster than the air sensors. It can therefore be checked whether
the sensors are crossed over.
Principle to b)
The compressors are switched on for a limited time only. The evaporator temperatures are
then checked before switching on and after switching off and the measurements compared
with pre-set minimum values.
Principle to c)
A defective magnetic valve (not switched) would result in cooling of the refrigeration
evaporator sensor as well (step 2).
Princple to d)
If the longfresh fan does not function correctly, the longfresh air sensor would not be cooled
sufficiently.
If, after completion of steps 2 and 3, no fault was found, the LCD displays a flashing 10 and
the compressor is switched off. Now the refrigerator door must be opened to initiate the next
test step. Any fault found is displayed in code (see point 10).
