24 E
FREEZER
DEFROST
ERROR
Connector Slipped-Out or Open- Contact,
Wire Cut or Short- Circuited, Defective
Thermistor, or When it keeps heating during
Fridge Defrost even after it does defrosting
for 80 minutes.
After separating MAIN PCB CN70 wire from
PCB, resistance value between CN70
Brown
↔
Black(refer to the Circuit Diagram
for the resistance value) When it is 0 Ohm,
check if the Heater is short and when it is
Ohm, check if the wire or the thermal fuse is
open.
