Name: Samsung RF27T5241SR
Brand: Samsung

Question 1

What does error code C-FAN ERROR mean on Samsung RF27T5241SR?

Accepted Answer

Condenser fan in the machine compartment is not spinning. Cause: Fan motor mechanical failure or obstruction; Bad wiring connection; No pulse signal returned to MICOM; Main PCB driver failure.

Question 2

What does error code COMP IPM FAULT mean on Samsung RF27T5241SR?

Accepted Answer

The compressor inverter power module has detected a fault and shut down. Cause: IPM internal fault; Overcurrent condition; IPM voltage too low (under 13.5V); Solder defect on inverter PCB.

Question 3

What does error code F-DEF ERROR mean on Samsung RF27T5241SR?

Accepted Answer

Freezer defrost heater is not working — ice may build up on evaporator. Cause: Defrost heater open or shorted; Bimetal thermoprotector tripped or open (off at 140°F/60°C, resets at 104°F/40°C); Thermal fuse blown (109°C/228°F cutoff, one-shot non-resettable); Wiring harness disconnection.

Question 4

What does error code F-FAN ERROR mean on Samsung RF27T5241SR?

Accepted Answer

Freezer fan motor is not spinning or not sending a rotation signal. Cause: Fan motor mechanical failure (foreign object blocking, ice buildup); Bad wiring connection to fan motor; No pulse signal returned to MICOM after motor on command; Main PCB relay or driver failure.

Question 5

What does error code F-SENSOR ERROR mean on Samsung RF27T5241SR?

Accepted Answer

Freezer temperature sensor has failed or disconnected. Cause: Bad connector contact at CN20; Open or shorted thermistor; PCB solder defect (iced solder, solder bridge, disturbed solder).

Question 6

What does error code R-SENSOR ERROR mean on Samsung RF27T5241SR?

Accepted Answer

Refrigerator compartment temperature sensor failed or disconnected. Cause: Bad connector contact at CN20; Open or shorted thermistor; PCB solder defect.
