Samsung 'Refrigerator' Diagnostic Code Quick Guide
LED TROUBLE
Ice Maker Sensor Error- open or short-circuit, connector failure.
Cause is also a temperature reading > 122°or < -58 ° F
Refrigerator Room Sensor Error- open or short-circuit, connector
failure. Cause is also a temperature reading > 122°or < -58 ° F.
Ref. Defrost Sensor Error- open or short-circuit, connector failure.
Cause is also a temperature reading > 122°or < -58 ° F
This error indicates the Refrigerator Evap Fan is not spinning at the
correct RPM or the fan feedback line is open.
This error indicates the Ice tray has not returned to level after an ice
harvest. The error is displayed after three failed attempts.
Refrigerator Room defrost heater- open or short-circuit, connector
failure, or defective temperature fuse/bi-metal. Defrost on over 80
minutes
Sensor system in Pantry Room errors
CR Room Sensor Error- This can be an open or short-circuit, contact
failure. Cause is also a temperature reading > 122°or < -58 ° F.
Error is displayed when the water reservoir tank heater is open or
shorted
Ambient Temp. Sensor Error- open or short-circuit, connector failure.
Cause is also a temperature reading > 122°or < -58 ° F
Freezer Compartment Sensor Error- open or short-circuit, connector
failure. Cause is also a temperature reading > 122°or < -58 ° F
Freezer Room Defrost Sensor Error- open or short-circuit, connector
failure. Cause is also a temperature reading > 122°or < -58 ° F
This error indicates the Freezer Evap. Fan is not spinning at the
correct RPM or the fan feedback line is open.
This error indicates the Condenser Fan is not spinning at the correct
RPM or the fan feedback line is open.
Ice Room Sensor Error- open or short-circuit, connector failure.
Cause is also a temperature reading > 122°or < -58 ° F
Freezer defrosting heater- open or short-circuit, connector failure, or
defective temperature fuse/bi-metal. Defrost on for over 80 minutes
This error indicates the Ice Room Compartment Evap. Fan is not
spinning at the correct RPM or the fan feedback line is open.
This error is not applicable, if the error is detected during diagnostic
testing please ignore it.
