Samsung Heat Pump Error Code E561

E561 indicates a discharge temperature sensor breakaway condition on the digital compressor. This means the control board has detected that the sensor monitoring compressor discharge temperature is either physically detached from its mounting holder or has failed internally. The system shuts down to protect the compressor from unmonitored high-temperature operation.

No, you should not attempt to bypass or continuously reset the unit to keep it running with E561 active. The discharge temperature sensor is a safety device that protects the compressor from overheating. Operating without a functioning sensor risks serious compressor damage, which is a much more costly repair than addressing the sensor fault directly.

Resetting the unit may temporarily clear the error code, but E561 will return as soon as the control board checks the discharge temperature sensor and detects the same fault condition. A reset does not fix the underlying problem, whether that is a detached sensor, a broken holder, or a failed sensor. The sensor and its mounting must be inspected and corrected before the fault will clear permanently.

If the sensor has simply come loose from its holder, reseating it correctly may resolve the error, and a careful DIYer comfortable working around HVAC equipment can attempt this. However, verifying the sensor resistance value requires a multimeter and knowledge of expected thermistor readings. If the sensor or wiring needs replacement, a qualified HVAC technician is recommended, especially since the repair involves working near refrigerant-carrying components under pressure.

If the sensor simply needs to be reseated in its holder, labor costs may range from around $75 to $150 for a service call. Replacing the discharge temperature sensor itself typically costs between $100 and $250 including parts and labor. If the wiring harness or control board is also involved, costs can be higher, potentially ranging from $200 to $600 or more depending on the components required.
