The Samsung mini split air conditioner is a popular choice for homeowners and businesses due to its energy efficiency, quiet operation, and versatile features.

Resetting the CF code on a Samsung mini split is a straightforward process, but it’s essential to follow the proper steps to ensure the unit’s optimal performance and longevity.

Preparing to Reset the CF Code

Before you begin the process of resetting the CF code, it’s crucial to gather the necessary tools and materials. You’ll need the following:

  1. A soft-bristled brush or a vacuum cleaner with a brush attachment.
  2. A mild detergent or cleaning solution.
  3. A clean, well-ventilated area to dry the filter.
  4. The remote control for your Samsung mini split.

  1. Turn off the Unit: Begin by turning off the Samsung mini split unit and disconnecting it from the power source.
  2. Remove the Filter: Locate the air filter, which is typically located on the front or side of the indoor unit. Gently press forward and lift the filter straight up to remove it.
  3. Inspect the Filter: Carefully inspect the air filter for any visible dirt, dust, or debris. If the filter appears heavily soiled, it’s time to clean it.
  4. Clean the Filter: Use a soft-bristled brush or a vacuum cleaner with a brush attachment to gently remove any loose dirt or debris from the filter. Avoid using water or any cleaning solutions at this stage.
  5. Soak the Filter: In a clean sink or container, prepare a solution of warm water and a mild detergent. Submerge the filter in the solution and let it soak for approximately 30 minutes.
  6. Rinse the Filter: After the soaking period, rinse the filter thoroughly under running water to remove any remaining dirt or detergent.
  7. Dry the Filter: Carefully shake off any excess water from the filter and place it in a well-ventilated area to air dry completely. Avoid exposing the filter to direct sunlight, as this can cause it to become brittle.

Resetting the Filter Cleaning Reminder

  1. Reinstall the Filter: Once the filter is completely dry, carefully reinstall it into the indoor unit, ensuring that it is properly aligned and secured in place.
  2. Reset the Filter Cleaning Reminder: Locate the “Options” button on your Samsung mini split remote control. Press and hold the “Options” button until the display shows the filter cleaning reminder.
  3. Cycle to the Filter Reset Option: Use the arrow keys on the remote control to cycle through the options until you reach the “Filter Reset” option.
  4. Confirm the Filter Reset: Press the “Set” button on the remote control to confirm the filter reset. The CF code should now be cleared, and the filter cleaning reminder will be reset.

Maintaining the Air Filter

To ensure the continued efficient operation of your Samsung mini split, it’s recommended to clean the air filter every 2-4 weeks, or whenever the CF code appears on the indoor unit display. The frequency of cleaning may vary depending on factors such as usage, environmental conditions, and the number of occupants in the space.

By following these steps, you can effectively reset the CF code on your Samsung mini split and maintain the optimal performance of your air conditioning system. Remember to consult your Samsung mini split’s user manual for any additional guidance or specific instructions related to your model.
