Error Code E122 / 122 – Indoor Coil Sensor Fault
Samsung Error Code E122 (or 122) typically indicates an indoor coil (evaporator) temperature sensor fault. This sensor prevents freezing and ensures efficient cooling. If it fails, your unit may freeze up, run inefficiently, or shut down to protect itself.
Symptoms include weak airflow, reduced cooling, ice build-up on the indoor unit, or water leaks once ice melts. In some cases, dirty filters and restricted airflow can trigger abnormal coil readings, even if the sensor is still functional.
✅ Hycool Air Conditioning Sydney can test Samsung coil sensors, clean the system, restore airflow, and repair E122 faults properly. If E122 appears, call Hycool now.
