Samsung support says: RF23HCEDTSR Error Codes/Messages/Blinking
All Samsung refrigerators are equipped with an onboard diagnostic system. If it detects an error/fault, it will display a specific code. Some models display a code such as 22E, however some models use the line segments from the numbers on the display, and this fault code will show instead of the temperatures.
If the unit is displaying an error or fault code, and it is not one of the situations in the following section, it will require service.
Important: Do not unplug the refrigerator. Unplugging the refrigerator will erase the diagnostic code that the technician uses to perform an accurate diagnosis, and will not resolve the issue causing the error code. The exception is error codes 88 88, 83E, 85E, or 86E. If and only if the display is showing one of these error codes, then unplug the refrigerator for 60 seconds. (The refrigerator can also be cut at the circuit breaker instead.) If the code returns, the refrigerator requires service.
Codes and Display Messages that are Commonly Misinterpreted:
Note: When all of the icons on the display are flashing after being plugged in, or after a power outage, this is normal. The fridge is running a self diagnostic when all of the icons are flashing.
OF OF or O FF: If the refrigerator is displaying OF OF or O FF, it is in Cooling Off/Demo Mode. Click here for instructions on taking the refrigerator out of Cooling Off/Demo Mode.
Flashing Temperature: If the temperature inside of the unit rises above 59°F, the display will blink and a chime will sound. The flashing display and chime sound will stop as the unit cools down. For more information, click here.
PC ER: This code indicates a communication issue between the door and the main unit. Unplug the refrigerator, and check the wire harness above the door (instructions are available in the user manual, the first couple steps under the section about removing the refrigerator doors). Disconnect and reconnect the wire harness, and restore power to the unit. If the error code returns, service is required.
Electronic Components Removed: If a component such as an ice maker or light is removed from the refrigerator, in time, this will result in an error/fault code. Unplugging the unit, re-installing the missing part(s), and then plugging the unit back in will clear the code.
