Samsung Air Conditioner Error Code 264

Error code 264 indicates a discharge temperature sensor dislocation error on fixed scroll compressor 3. The system has determined that the sensor monitoring the discharge temperature of this specific compressor is not in its correct mounting position. This is a positional fault, meaning the sensor has physically shifted rather than failed electrically. A technician needs to inspect and correctly reposition the sensor to resolve the fault.

Continuing to operate the unit with this error active is not recommended. The discharge temperature sensor on compressor 3 protects the compressor from overheating, and if it is out of position, the system cannot accurately monitor that compressor's thermal state. Running the unit without proper temperature oversight risks compressor damage, which is a much more costly repair than fixing the sensor dislocation.

If the repair only requires repositioning and securing the existing sensor, labor costs may range from around 75 to 200 dollars depending on the technician and system accessibility. If the sensor itself needs replacement, parts and labor combined could range from 150 to 400 dollars or more, depending on the specific sensor and local service rates. Commercial or multi-zone systems may incur higher diagnostic fees due to their complexity.

The first step is to locate the discharge temperature sensor on fixed scroll compressor 3 and verify it is seated in the correct mounting position. If the sensor has slipped or been incorrectly installed, repositioning and securing it may clear the error. If the mounting hardware is damaged, it will need to be replaced to keep the sensor in position. A qualified HVAC technician should perform this inspection, as it involves working inside a commercial or multi-zone refrigerant system.

A simple power reset is unlikely to permanently clear error code 264 because the fault is caused by the physical position of the sensor rather than a temporary electronic glitch. The error will typically return once the system restarts and checks the sensor readings again. The underlying positional issue must be corrected before the error will stay cleared.
