Samsung Air Conditioner Error Code E260

The E260 code means that the outdoor unit COND OUT sensor, which monitors condenser outlet temperature, has been detected as physically separated or detached from its mounting position. The system cannot reliably read condenser temperatures without the sensor properly seated, so it generates this fault to alert the user or technician. The fix typically involves locating the sensor on the outdoor condenser and reattaching it correctly.

Operating the unit with the COND OUT sensor detached can cause the control board to make incorrect decisions about compressor load and refrigerant flow, since it is missing accurate condenser outlet temperature data. Over time this can contribute to compressor stress or inefficient operation. It is best to address this fault promptly rather than continuing to run the system in a faulted state.

If the sensor only needs to be reseated, a service call to diagnose and reattach it would typically fall in the range of $75 to $150 depending on local labor rates. If the retention clip or the sensor itself requires replacement, parts costs would add roughly $20 to $80 to that total, putting the overall repair in the $100 to $230 range in most cases.

If you are comfortable working around outdoor HVAC equipment and can safely access the outdoor unit, you may be able to resolve this by visually locating the COND OUT sensor on the condenser outlet tubing and pressing it back into its retaining clip. However, if the clip is broken or you cannot identify the correct sensor position, a qualified technician should perform the repair to avoid incorrect reassembly that could cause further faults or system damage.

A simple power reset may temporarily clear the fault code display, but if the sensor is still physically detached the error will return once the system attempts to read the sensor during operation. The underlying cause, the detached sensor, must be physically corrected before the fault will remain cleared.
