8. Operation and Functions
5. Control way of Error (if any)
1) "F1" error
Cause : F-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN14
of the Main PCB.
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 CN15
of the Main PCB.
If R-sensor is disconnected or shorted , change the F-sensor in the fridge compartment.
How to reset : If R-sensor is normal, the error is terminal temperature.
3) "i5" error
Cause : IM-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN19
of the Main PCB.
If IM-sensor is disconnected or shorted , change the IM-sensor in the fridge compartment.
How to reset : If IM-sensor is normal, the error is terminal temperature.
4) "FD" error
Cause : FD-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN15
of the Main PCB.
If FD-sensor is disconnected or shorted , change the FD-sensor on the evaporator.
How to reset : If FD-sensor is normal, the error is terminated automatically.
5) "rD" error
Cause : RD-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN15
of the Main PCB.
If RD-sensor is disconnected or shorted , change the RD-sensor on the evaporator.
How to reset : If RD-sensor is normal, the error is terminated automatically.
6) "iD" error
Cause : IR-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN15
of the Main PCB.
If IR-sensor is disconnected or shorted , change the IR-sensor on the evaporator.
How to reset : If IR-sensor is normal, the error is terminated automatically.
7) "rt" error
Cause : RT-sensor disconnection or short
Check point : Measure the resistance between both terminals after separating CN15
of the Main PCB.
If RT-sensor is disconnected or shorted , change the RT-sensor on the xxxxx.
How to reset : If RT-sensor is normal, the error is terminated automatically.
To avoid risk of electrical shock that can cause death or severe personal injury,
WARNING
!
disconnect unit from power before servicing unless tests require power.
