1) “F1” error
Cause : F-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN8 (or CN15)
of the Main PCB. (Refer to the 5-2.)
If F-sensor is disconnected or shorted , change the F-sensor in the freezer compartment.
How to reset : If F-sensor is normal, the error is terminal temperature.

2) “R1” error
Cause : R-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN7 (or CN14)
of the Main PCB. (Refer to the 5-2.)
If R-sensor is disconnected or shorted , change the F-sensor in the refrigerator compartment.
How to reset : If R-sensor is normal, the error is terminal temperature.
7) “F3” error
Cause : in case defrosting return is done by time limit of 80 min
Check point : Measure the resistance between both terminals of the defrost heater.
(Assembled with evaporator)
If the resistance is ∞Ω (disconnected) or 0Ω (short) change the
3) “rt” error
Cause : RT-sensor disconnection or short (full down)
Check point : Measure the voltage of “A” part on the Main PCB.
If the voltage is 0.5V~4.5V, it is normal.
If the voltage is 0V (short) or 5V (disconnected), change the RT-sensor on the Main PCB
How to reset : If RT-sensor is normal, the error is terminated automatically.

4) “d1” error
Cause : D-sensor disconnection or short (full down)
Check point : Measure the resistance between both terminals after separating CN8 (or CN15)
of the Main PCB. (Refer to the 5-2.)
If D-sensor is disconnected or shorted , change the D-sensor on the evaporator.
How to reset : If D-sensor is normal, the error is terminated automatically.
5) Door error (“dF” “dR” “dH” on display)
Cause : in case it senses that door is open for more than 1 hour.
Check point : F/R door is opened or not.
6) “C1” error
Cause : in case comp. works for over 3 hours when D-sensor temp. is over -5℃
Check point : Refrigerant leakage.
8) “d2” mode (A/S forced defrosting mode)
Push “REFRIGERATOR SET” button 5 times while pushing “FREEZER SET” button
simultaneously.
Control : A/S forced defrosting control (Pre-cool is deleted)
If D-sensor temp. is over 10℃, the mode is terminated automatically.
Refer to the 4-3. .
5. Control way of Error (if any)
