Name: Samsung RF25C5551SR
Brand: Samsung

Question 1

What does error code AMBIENT-SENSOR mean on Samsung RF25C5551SR?

Accepted Answer

External ambient temperature sensor is faulty. Cause: Bad connector at CN60 pins 3 and 5; Open or short in ambient sensor wiring; Failed thermistor; PCB solder defect at R228.

Question 2

What does error code AUTOFILL-OVERFLOW mean on Samsung RF25C5551SR?

Accepted Answer

AutoFill pitcher has detected a water overflow condition. Cause: Water fill valve stuck open; Overflow sensor malfunction; Blocked pitcher sensor; Autofill system overfilling.

Question 3

What does error code CFAN-ERROR mean on Samsung RF25C5551SR?

Accepted Answer

Compressor area cooling fan is not running. Cause: Fan motor failure; Bad wiring at CN40; Fan blade obstructed by debris; No rotation feedback pulse to MICOM.

Question 4

What does error code COMP-IPM-FAULT mean on Samsung RF25C5551SR?

Accepted Answer

Compressor power module has detected an internal fault. Cause: IPM overcurrent or overtemperature; DC 15V supply below 13.5V; Short circuit on inverter PCB; Compressor winding fault.

Question 5

What does error code COMP-IPM-SHUTDOWN mean on Samsung RF25C5551SR?

Accepted Answer

Compressor inverter power module has forcibly shut down. Cause: PCB solder short on inverter circuit; DC 15V output below 13.5V; Compressor or cycle fault.

Question 6

What does error code COMP-LOW-VOLTAGE mean on Samsung RF25C5551SR?

Accepted Answer

Incoming power voltage is too low for the compressor to run safely. Cause: Supply voltage below AC 60V (110-127V systems) or AC 106V (220-240V systems); Short resistor R514 (DC link resistor) on PCB; Poor power connection or extension cord.

Question 7

What does error code COMP-MOTOR-CONSTRAINT mean on Samsung RF25C5551SR?

Accepted Answer

Compressor motor is jammed or running at dangerously low speed. Cause: Locked rotor operating within 5 seconds; Compressor operating below 1000 RPM for more than 5 seconds; Large sudden input voltage change; Failed compressor or refrigeration cycle blockage.

Question 8

What does error code COMP-OVER-VOLTAGE mean on Samsung RF25C5551SR?

Accepted Answer

Incoming power voltage is too high for the compressor to run safely. Cause: AC input voltage above AC 155V (110-127V models) or AC 310V (220-240V models); Short resistor R511, R512, or R513 (DC link resistors) on PCB.

Question 9

What does error code COMP-START-FAILURE mean on Samsung RF25C5551SR?

Accepted Answer

Compressor tried to start but failed due to electrical or mechanical fault. Cause: Short between compressor U, V, W phase terminals (CN102); Short among IC3 (IPM) pins 1-24; IPM operating voltage dropped below DC 13.5V; Compressor winding fault; Failed refrigeration cycle (blocked).

Question 10

What does error code DAMPER-HEATER-ERROR mean on Samsung RF25C5551SR?

Accepted Answer

The drawer area damper anti-condensation heater has failed. Cause: Open damper heater element; Short circuit in heater wiring; Bad connector at CN40 pins 25 and 27.
