Samsung Air Conditioner Error Code E130

E130 means that both the evaporator inlet and evaporator outlet temperature sensors on the indoor unit have been detected as disconnected at the same time. These sensors monitor refrigerant temperature across the indoor heat exchanger coil. Without readings from both sensors simultaneously, the unit cannot safely regulate the refrigeration cycle and will trigger this fault to protect the system.

You should not continue operating the unit while E130 is active. The indoor unit control board relies on both evaporator sensors to prevent the coil from freezing and to manage cooling output correctly. Running the system without this temperature feedback risks ice buildup on the coil, reduced airflow, and potential compressor damage over time.

If the fix is simply repositioning and reconnecting the two displaced sensors, the repair may only cost a service call fee, typically in the range of $75 to $150 depending on your location and technician. If the sensor harness is damaged and needs replacement, parts and labor together could range from $100 to $250. Replacing the indoor control board, in the unlikely event it is responsible, could bring the total to $200 to $400 or more.

Start by opening the indoor unit and locating the two EVA IN and EVA OUT sensors clipped onto the heat exchanger coil. Check that both sensors are seated in their mounting clips and that their wiring connectors are fully plugged into the harness and control board. Reattach any displaced sensors, restore power, and the error should clear once the control board detects valid signals from both sensors. If the code returns, inspect the harness for damage and test the sensors for correct resistance values.

A power reset alone will not permanently clear E130 if the sensors are still physically displaced or disconnected. The fault will return as soon as the control board checks the sensor inputs again. The underlying cause, meaning the displaced or disconnected sensors, must be corrected first. Once both sensors are properly repositioned and connected, the error should not reappear after a reset.
