Samsung Air Conditioner Error Code E107

E107 means the evaporator outlet temperature sensor on the indoor unit has separated from the refrigerant pipe it is supposed to monitor. The sensor needs physical contact with the pipe to send accurate temperature readings to the control board. When it detaches, the readings become unreliable and the system triggers this fault code. The fix typically involves reattaching or replacing the sensor.

It is not advisable to continue running the unit while E107 is active. Without accurate evaporator outlet temperature data, the control board cannot regulate the refrigerant cycle correctly, which could lead to issues such as coil icing or inefficient operation. The unit may shut itself down automatically as a protective measure. Address the sensor issue before resuming normal use.

If the sensor only needs to be repositioned and secured, the repair may cost little to nothing beyond a service call fee, which typically ranges from $50 to $100 or more depending on your location. If the sensor itself needs to be replaced, parts and labor combined generally range from $75 to $200. A broken mounting clip alone is an inexpensive part, though labor charges still apply if a technician is performing the work.

In many cases, yes. If the sensor has simply come loose from the pipe, you can open the indoor unit cover, locate the EVAP OUT sensor on the evaporator outlet pipe, and press it firmly back into its mounting clip. If the clip is broken, you may need a replacement clip or a new sensor, which a knowledgeable DIYer can install. If the sensor itself is damaged or the code persists after reattachment, a technician should diagnose further.

A simple power reset may temporarily clear the E107 code, but it will return if the sensor is still detached from the pipe. The underlying physical issue must be resolved first. After reattaching the sensor securely to the evaporator outlet pipe, a reset will allow the unit to restart and verify the fix.
