For any anormality, check the sealing door.
Unplug the product, remove the fan cover
and check the resistance in the defrost
control part.
Connect the refrigerator, remove the PCB
cover and start Test Mode 2 (press twice the
button on PCB).
Resistance is the same as
the value from the chart?
Yes: Keep checking the
defrost sensor.
No: Change the defrost
resistance.
1. Refer to Defrost Sensor
procedure.
2. Keep checking the fuse.
Change defrost controller.
NOTE: Defrost sensor must be cold for start this mode (less than
13 °C).
The next sequence confirms that you started Test Mode 2:
