Samsung Air Conditioner Error Code E267

E267 indicates that the top temperature sensor on compressor 2 is detached or has lost its electrical connection. The control board cannot read a valid temperature from that sensor location, so the system generates this fault to protect the compressor from unmonitored operation. This code is most commonly found on Samsung multi-compressor systems such as larger multi-zone units.

Running the system with E267 active is not recommended. The top sensor on compressor 2 provides critical temperature data that helps prevent the compressor from overheating. Without reliable readings from that sensor, the control system cannot properly protect the compressor, which could lead to premature failure of an expensive component.

A power reset may temporarily clear the error code, but if the underlying cause such as a detached sensor or broken wire has not been corrected, E267 will return once the system runs and checks that sensor circuit again. A reset should only be performed after the sensor attachment and wiring have been inspected and confirmed to be in good condition.

If the sensor has simply vibrated loose from its mounting bracket, a knowledgeable DIYer can reseat it after safely powering down the unit. However, if the wiring harness is damaged or the sensor has failed, a qualified technician with the right tools for resistance testing and component replacement will be needed. Working inside an air conditioner involves high-voltage components, so caution is essential.

If the fix is simply reseating a detached sensor, the cost may be limited to a service call fee, typically in the range of $75 to $150. If the sensor itself needs replacement, parts and labor combined generally range from $100 to $300 depending on the unit model and local labor rates. A damaged wiring harness can add to that estimate depending on the extent of the repair.
