Samsung Air Conditioner Error Code E241

E241 indicates a discharge temperature sensor error caused by an open or short circuit in the sensor or its wiring. The discharge temperature sensor monitors refrigerant temperature at the compressor outlet, and the control board uses this reading to protect the compressor. When the board detects an invalid signal, it logs E241 and may shut the unit down. Diagnosis begins with checking the sensor connector at the PCB and measuring sensor resistance.

Running the unit while E241 is active is not recommended. The discharge temperature sensor protects the compressor from overheating by providing real-time outlet temperature data to the control board. Without a valid sensor reading, the unit cannot properly manage compressor operation, and continued use risks compressor damage, which is a significantly more expensive repair than fixing the sensor.

Repair costs depend on the root cause. A replacement discharge temperature sensor typically falls in the range of $20 to $75 for the part alone. Adding professional labor, total repair costs generally range from $100 to $250 for a sensor or wiring harness replacement. If the control PCB itself has failed, costs can rise significantly higher, often in the range of $200 to $500 or more depending on the unit model and part availability.

A knowledgeable DIYer can perform initial checks such as reseating the sensor connector and visually inspecting the wiring harness for damage. However, measuring sensor resistance accurately requires a multimeter and some familiarity with reading resistance values relative to temperature. Replacing the discharge temperature sensor or diagnosing a PCB fault typically requires a qualified technician, especially since the work involves components near refrigerant lines.

A power reset may temporarily clear the error code from the display, but if the underlying fault in the sensor circuit has not been repaired, the code will return as soon as the unit attempts normal operation. A reset is only useful as a first step to confirm whether the fault is intermittent, such as a loose connector that reseated itself, rather than a permanent fix for a damaged sensor or wiring.
