c) Open door Alarm
When any of the doors (Freezer or Refrigerator) remains open
more than
2 minutes
, the Electronic Control system will emit a
sound Alarm - “BEEP” , the Open Door icon (corresponding to
the compartment/ door) will blink and the Caution Alarm Icon
will switch on,
indicating that it’s open.
To turn off the
sound sign just
close the door or press the turn off Alarm (OK) key
, in this second
situation, the Open Door Icon will keep blinking until the door is closed.
Remark
When the
open
door sound
alarm is disabled by the OK key (Alarm off) and the door remain open, this
Caution Alarm will be activated again 2 minutes later.
After 6 minutes,
if the door has not been closed yet,
a new Caution
open door
Alarm
will be enable and the
Electronic Control
will assume a safety routine
, turning off the Refrigerator lamp, putting in action the Fan
Motors (Freezer & Refrigerator) and the Compressor, even whether the doors are open, as it’s working in
normal cycle, trying to keep food refrigerated.
When constant, there is the chance of a real
Technical Failure
, check its source.
Check Point:
- Reed Switch board – must operate correctly
- The magnet on the doors (Freezer and Refrigerator) must be present and correctly positioned
- If the doors are adjusted and closing correctly;
- Poor contact between terminals/ connectors – CN4 (Interface board) and CN2 (Reed Switch Board) at
Electronic Control, upper wiring harness between freezer Door and Cabinet;
- Interrupted/ damaged wires.
d) Temperature Alarm
If the Electronic Control detects a High Internal Temperature
(above – 8
o
C), at the Freezer compartment, it will activate the Alarm
Icon and the Freezer Temperature Icon
“–– ––”
(
2 dashes
) will blink.
Note:
To prevent “wrong” Alarm, this Alarm status is disabled on the following circumstances:
•
During the first 6 hours after the product is connected to the energy
•
During defrost process
•
During the first 2 hours after a defrost
•
During the first 2 hours that one of the doors was open
If the product takes over
the temperature reaching –11
o
C, the Alarm will be automatically disabled and
the product will return to the normal operation.
When constant, there is the chance of a real
Technical Failure
, check its source.
Check Point:
- If the Freezer compartment was loaded with “hot food”, increasing the internal temperature of the
compartment. Wait until the internal temperature has stabilized.
- Poor contact between terminals/ connectors – CN3 (Temperature Sensors) and CN2/ CN1 load
components at Electronic Control; Compressor, Fan Motors, others . Do the Self Test Routine
- Also check; Ice blockage, leakage of refrigerant fluid, Compressor’s low pumping, etc.
