Chapter 8 Trouble shooting
8-1. Common problems and solutions
8-1-1 Symptom: food in the fridge storage compartment is frozen
Check:
1) Verify that the temperature in the fridge storage compartment is too low and the food is frozen there;
2) Remove the decoration piece of the refrigeration air-duct. Detach the 2 screws and take out the air
door-foam assembly. Press the “Refrigeration OFF” button to see if the air door closes
automatically. If the air door closes tightly, continue to next step. If the air door does not close
normally, continue to step 6).
3) Disconnect the connection wires of the air door and the LED lamps. Take out the air door-foam
assembly. Tear the adhesive tape wrapped around the foam and separate the foam. Check if the
seal between the air door and the foam is tight.
4) If the seal is tight, check if the fridge storage temperature sensor R1 is OK.
5)If the sensor R1 is OK, then the main control panel is probably malfunctioning.
6) If the wiring of the air door is OK, check the circuit from the connector of the main control panel to
the connector in the cabinet. If there is no problem in this circuit, the air door is malfunctioning.
Solutions:
1) If the seal between the air door and the foam is found to be not tight, please affix seal strip on the
interface between the air door and the foam;
2) If the sensor R1 is malfunctioning, please replace it with a new one;
3) If the main control panel is malfunctioning, please replace it with a new one;
4) If the connector of the air door is connected with reverse polarity, please reconnect it correctly;
5) If the air door is malfunctioning, please replace it with a new one.
8-1-2 Symptom: the buzzer beeps to alarm
1) Test across pin 1 and pin 3 of CN1 on the main control panel. The 2 pins should be switched to
conduction when the door is closed and disconnected when the door is open.
2) If pin 1 and pin 3 of CN1 are disconnected in both cases, please remove the front decoration strip to
see if the door switch is still in the slot.
8-1-3 Symptom: no defrosting
Check:
1) Activate the forced defrosting function by double pressing the button on the main control panel.
Then, check if the temperature of the defrosting heating wire is rising.
If the temperature of the heating wire does not change, remove the fan cover plate to check if all
the connectors are connected properly and test if there is 220V voltage output across the
terminals of the heating wire.
