Name: Samsung RF29BB8600QL
Brand: Samsung

Question 1

What does error code AMBIENT_SENSOR mean on Samsung RF29BB8600QL?

Accepted Answer

Ambient air temperature sensor reading is out of normal range. Cause: Connector CN60 pins 3/5 loose or damaged; Ambient sensor open or shorted; HUM-TEMP sensor assembly failure.

Question 2

What does error code AUTOFILL_OVERFLOW mean on Samsung RF29BB8600QL?

Accepted Answer

AutoFill pitcher has overflowed. Cause: AutoFill pitcher overflow; Float or overflow switch stuck or defective; Water fill valve not closing.

Question 3

What does error code CIRCUIT_FAN_ERROR mean on Samsung RF29BB8600QL?

Accepted Answer

Condenser fan in the machine compartment is not running. Cause: C-FAN motor failure; Obstruction in machine compartment; Wiring bad contact at CN40; MAIN PCB failure.

Question 4

What does error code COMP_IPM_FAULT mean on Samsung RF29BB8600QL?

Accepted Answer

Inverter power module has detected a fault. Cause: IPM internal overcurrent or overheat; Inverter PCB soldering defect; DC 15V supply dropped below 13.5V; Compressor or refrigerant cycle issue.

Question 5

What does error code COMP_IPM_SHUTDOWN mean on Samsung RF29BB8600QL?

Accepted Answer

Inverter power module executed an emergency shutdown. Cause: Inverter PCB soldering defect (short-circuited components); DC 15V output dropped below 13.5V; Compressor overcurrent; Refrigerant cycle overload.

Question 6

What does error code COMP_LOW_VOLTAGE mean on Samsung RF29BB8600QL?

Accepted Answer

Input voltage to the inverter has dropped too low. Cause: Supply voltage dropped below AC 60V (for 110V~127V models); Weak power circuit or extension cord voltage drop; Short on resistor R514 (DC link resistor).

Question 7

What does error code COMP_MOTOR_CONSTRAINT mean on Samsung RF29BB8600QL?

Accepted Answer

Compressor motor is seized or cannot rotate. Cause: Compressor seized or mechanically locked; Operating with locked rotor for more than 5 seconds; Running below 1000 RPM for more than 5 seconds; Large instantaneous input voltage change; Refrigerant cycle issue.

Question 8

What does error code COMP_OVER_VOLTAGE mean on Samsung RF29BB8600QL?

Accepted Answer

Input voltage to the inverter is dangerously high. Cause: Input voltage exceeded AC 155V (for 110V~127V models); Short among resistors R511, R512, R513 (DC link resistors).

Question 9

What does error code COMP_POSITION_ERROR mean on Samsung RF29BB8600QL?

Accepted Answer

Inverter cannot detect compressor rotor position. Cause: Compressor wiring CN102 open circuit; Bad soldering on resistor R1; Short or open on R515, R516, R517; Compressor internal failure; Refrigerant cycle issue.

Question 10

What does error code COMP_START_FAILURE mean on Samsung RF29BB8600QL?

Accepted Answer

Compressor fails to start up. Cause: Short between compressor U, V, W phase terminals (CN102); Short among IPM IC3 pins (#1~24); DC 15V supply dropped below 13.5V; Compressor internal failure; Refrigerant cycle issue.
