F-DEFROST
ERROR
F-ROOM HEATER (SENSOR HOUSING SLIP-
OUT, CONTACT DEFECT, WIRE CUT, WIRE
SHORT OR TEMP FUSE DEFECT)
WHEN DEFROST DOES NOT FINISH EVEN
AFTER A 70-MINUTE CONTINUOUS
HEATING, IT DISPLAYS THE ERROR.
AFTER SEPARATING THE MAIN PCB CN70 WIRE FROM
PCB, CHECK THE RESISTANCE BETWEEN BROWN
↔
ORANGE. IT SHALL BE WITHIN ***OHM. (THE
RESISTANCE VARIES ACCORDING TO THE INPUT
POWER.) WHEN THE RESISTANCE IS 0 OHM,CHECK IF
THE HEATER IS SHORT AND WHEN IT IS
∞
OHM, CHECK
IF THE WIRE/TEMP FUSE IS OPEN

R-DEFROST
ERROR
R-ROOM HEATER (SENSOR HOUSING
SLIP-OUT, CONTACT DEFECT, WIRE CUT,
WIRE SHORT OR TEMP FUSE DEFECT)
WHEN DEFROST DOES NOT FINISH EVEN
AFTER A 80-MINUTE CONTINUOUS
HEATING, IT DISPLAYS THE ERROR.
AFTER SEPARATING THE MAIN PCB CN70 WIRE FROM
PCB,CHECK THE RESISTANCE BETWEEN WHITE

ORANGE.IT SHALL BE WITHIN ***OHM. (THE
RESISTANCE VARIES ACCORDING TO THE INPUT

Communication error with PLC modem
Note) PLC Communication modem will be applied optionally.
So even if the appliance which does not apply PLC displays this error digit, It is not defect.
