Samsung Air Conditioner Error Code E112

E112 indicates a Perfect fan sensor error on a Samsung air conditioner. The control board is not receiving a valid signal from the sensor that monitors the indoor fan motor. This fault can prevent the unit from operating normally until the sensor circuit is inspected and repaired.

It is not advisable to continue running the unit while E112 is active. The fan sensor fault may mean the indoor fan is not operating correctly, which can lead to reduced airflow, coil freezing, or further component damage. Shut the unit off and have it inspected before resuming use.

A power reset may temporarily clear the error display, but the code will return if the underlying sensor fault has not been resolved. Resetting without addressing the root cause is not a reliable fix. The sensor, wiring, and fan motor should be properly diagnosed and repaired to permanently clear the E112 code.

Some basic checks, such as inspecting the wiring harness and reconnecting any loose connectors, can be done by a knowledgeable DIYer. However, testing sensor output, evaluating motor condition, and replacing internal components typically require specialized tools and experience. If you are not comfortable working inside the unit, a qualified technician is recommended.

Repair costs vary depending on the root cause. A simple wiring fix or connector repair may cost relatively little in labor only. Replacing the fan sensor or fan motor typically costs more, with parts and labor combined ranging from roughly $100 to $400 or more depending on the unit model and your location.
