Samsung Air Conditioner Error Code E225

E225 means the outdoor unit condenser outlet (COND-OUT) temperature sensor has separated or become disconnected from its mounting position. The control board can no longer read a valid temperature at the condenser outlet, which is required for proper system operation. This is primarily a physical displacement fault rather than an electrical failure, and in many cases it can be resolved by locating and reseating the sensor.

It is not recommended to continue operating the unit while E225 is active. The COND-OUT sensor provides temperature data the control board uses to protect the system from overheating and to confirm correct refrigerant flow. Running the system without this input could allow operating conditions that would stress or damage compressor and refrigerant circuit components.

If the sensor only needs to be repositioned and clipped back into place, repair costs may be limited to a service call fee, typically in the range of $75 to $150 depending on your location and technician. If the mounting clip or the sensor thermistor itself needs replacement, parts and labor combined could bring the total to roughly $100 to $300. Costs vary based on unit model, parts availability, and local labor rates.

Start by powering down the unit and accessing the outdoor section to locate the COND-OUT sensor. Check whether the sensor has pulled out of its mounting clip on the condenser outlet line and reseat it firmly if so. Also inspect the sensor wiring connector to the control board harness to make sure it is fully engaged. If the clip is broken or the sensor itself is damaged, those components will need to be replaced before the fault will clear.

A simple reset is unlikely to permanently clear E225 because it is caused by a physical condition, specifically a displaced or disconnected sensor, rather than a transient software or communication fault. The error will typically return on startup if the underlying sensor separation has not been corrected. The sensor must be physically reattached and secured before a reset will result in normal operation.
