Samsung Air Conditioner Error Code 261

Error code 261 on a Samsung air conditioner indicates a digital compressor discharge temperature sensor dislocation error. This means the control board has determined that the sensor monitoring discharge temperature at the compressor is not in its correct position. The system flags this to prevent the compressor from running unprotected without accurate temperature data. A physical inspection of the sensor mounting is the required first step.

It is not advisable to continue operating the unit with error code 261 active. The discharge temperature sensor protects the digital compressor from overheating, and if it is out of position, the control board cannot accurately monitor compressor temperatures. Running the system in this condition risks compressor damage, which is a costly repair. Address the sensor issue before resuming normal operation.

A simple power reset may temporarily clear the error code, but it will return if the underlying problem with the sensor position or condition is not corrected. The control board will re-detect the dislocation condition once the unit attempts to operate and reads the sensor signal again. The root cause must be physically resolved by inspecting and correcting the sensor mounting before the error will stay cleared.

If you are comfortable working on outdoor HVAC equipment, you can inspect the discharge temperature sensor on the digital compressor to see if it has simply slipped out of its mounting position and reseat it yourself. However, if the mounting hardware is broken, the sensor wire is damaged, or the sensor itself needs replacement, a qualified technician should handle the repair. Working around the compressor and refrigerant lines carries safety risks and requires proper knowledge of the equipment.

If the sensor only needs to be repositioned in its mounting clip with no parts required, the cost would primarily cover a service call fee, typically in the range of $75 to $150. If the sensor, mounting hardware, or wiring harness needs replacement, parts and labor combined could range from $150 to $400 depending on the model and your location. A compressor replacement, if delayed diagnosis leads to compressor damage, would be significantly more expensive.
