Samsung Air Conditioner Error Code E106

E106 means the indoor unit evaporator inlet sensor has separated from the refrigerant pipe it is designed to monitor. Samsung air conditioners use this sensor to track refrigerant temperature entering the evaporator coil, and the unit will not operate normally if the sensor loses contact with the pipe. The error is a physical positioning fault, not necessarily a sign that the sensor itself is broken.

It is not recommended to continue operating the unit with E106 active. Without accurate inlet temperature data, the control board cannot properly regulate the refrigerant cycle or protect the system from conditions like coil icing or overheating. Running the unit in this state risks further component damage. Address the sensor position issue before resuming normal operation.

If the fix is simply reseating a detached sensor, the repair cost may only cover a service call fee, typically in the range of $75 to $150 depending on your location and service provider. If the sensor clip or thermistor itself needs to be replaced, parts costs are generally modest, with total repair costs likely falling in the $100 to $250 range. Costs can be higher if the issue is part of a larger problem requiring additional diagnosis.

In many cases yes, because the fix involves opening the indoor unit cover, locating the EVAP IN sensor on the evaporator inlet pipe, and pressing it back into contact with the pipe. Secure it using the original clip or insulating foam tape. If the sensor appears intact and is correctly repositioned but the error returns, further electrical diagnosis or sensor replacement may be needed and a technician should be called.

A power reset may temporarily clear the code, but if the sensor is still physically detached from the pipe, the error will return once the unit attempts to read the sensor during operation. The underlying cause, the sensor being separated from the pipe, must be corrected first. After repositioning the sensor, a reset should allow normal operation to resume.
