Check out the displayed error codes on Samsung indoor unit air conditioner
When the indoor unit's indicator blinks, first determine the type of code. It's not typically a product flaw. However, in rare circumstances, further service may call for a qualified engineer. Check out the examples and tips below. For expert repair, get in touch with the closest Samsung service center if an error code continues to occur.
Note: The actual design of the display panel may differ based on the model you have.

dF |
Automatic Defrost function (During the Defrost function or steam is produced on the outdoor unit) |
This is not a manufacturing defect (When the Heat mode is off, this function will be turned off.) |
• CF function
When the inside air filter has too much dust, your air conditioner is unable to draw in a sufficient amount of air. This may be the cause of the issue with the temperature and noise. We recommend cleaning the filter every 2 weeks or when the CF display code appears on the indoor unit display. (The CF display code means filter-cleaning reminder.)
Please check your air conditioner model below and follow the how-to guide to clean the air filter. This will give you cool and fresh air.
• dF (Defrost function)
When the Defrost function is on, the df indicator appears on the indoor unit display and steam is produced on the outdoor unit. Then the air conditioner stops running to prevent cold air from coming out of the indoor unit.
• Automatic Defrost
When the outdoor temperature is low and the humidity is high, frost may develop on the outdoor heat exchanger, which may decrease heating efficiency. When these conditions are met while Heat mode is on, the air conditioner runs the Defrost function for 5 to 12 minutes to remove frost from the outdoor heat exchanger.
Error codes requiring authorized service
When the air conditioner displays the E1 code on the display panel and won't turn on, it means the room thermistor (a device connected to the thermostat that detects the room temperature) is shorted or defective. Most of these cases need to be handled by an authorized repair person. Therefore, please contact the nearest Samsung service center.
