Samsung Air Conditioner Error Code P418

P418 indicates that the Samsung air conditioner has entered an oil collection operation, which is a built-in, automatic maintenance routine designed to return compressor lubricating oil that has migrated into the refrigerant circuit back to the compressor. This is not an error or fault code. The system will complete the cycle and resume normal operation automatically without any user action required.

Yes, it is completely safe. The unit is operating as designed when P418 is displayed. The oil collection routine is a protective measure that actually helps extend the life of the compressor by ensuring it maintains adequate lubrication. You do not need to turn the system off or take any precautions while this code is active.

There is no repair cost associated with P418 because it is not a fault condition. No parts, labor, or service calls are required. If a technician has been called to address this code, the visit cost would typically fall in the range of a standard diagnostic fee, which varies by region and provider, but no additional repair charges should apply once the technician confirms the system is functioning normally.

No repair or intervention is needed for P418. The code represents a normal automated process, not a malfunction. Simply allow the unit to complete the oil collection cycle, and the code will clear on its own. If the display continues to show P418 for an unusually extended period, it may be worth consulting a technician to confirm the controller is functioning correctly.

Resetting the unit is not necessary and may simply cause the oil collection cycle to restart from the beginning. The code will clear automatically once the routine completes its full cycle. Interrupting the process repeatedly by resetting the unit could delay the return of oil to the compressor, which is counterproductive.
