Samsung Air Conditioner Error Code 170

Error code 170 on a Samsung air conditioner indicates a conflict in temperature unit settings across the system's indoor units. Some units are set to Celsius while others are set to Fahrenheit, which the system does not allow. This is a configuration issue and not a sign of a mechanical or electrical failure. It is resolved by setting all indoor units to use the same temperature unit through their remote controllers.

No, error code 170 is not a safety concern. It is a configuration conflict related to temperature unit settings and does not involve any electrical hazard, refrigerant issue, or mechanical failure. However, leaving the error unresolved may cause control or communication issues between units, so correcting the settings promptly is recommended.

Because error 170 is a configuration issue and not a parts failure, the cost is typically limited to a service call fee if you hire a technician. That range can vary from around 75 to 200 dollars depending on your location and provider. If you are comfortable accessing remote controller settings yourself, there is no parts or repair cost involved at all.

To fix error 170, access the settings on each indoor unit's remote controller and verify the temperature unit selection. Set every remote controller on the system to the same unit, either all Celsius or all Fahrenheit, depending on your region and preference. Once all units are configured consistently, the error should clear without requiring a manual reset. No parts replacement is needed for this error.

A simple power reset will not permanently clear error code 170 because the underlying configuration mismatch will still exist after the reset. The error will return until the temperature unit settings are corrected on all remote controllers. Correct the settings first, and the code should clear on its own without needing an additional reset.
