Samsung RFG29 French door refrigerator error codes
These error code explanations can help you diagnose a problem with Samsung RFG29, RFG296, RFG297 and RFG298 French-door refrigerators.
These Samsung refrigerator models display an error code on the freezer and refrigerator temperature digital displays when the control detects a component failure. The freezer temperature display shows the number designation of the code and the refrigerator temperature display shows E.
When the control detects a communication error between the control panel and the electronic control board, the freezer temperature display shows Er and the refrigerator display shows Pc.
Refer to the chart below to find the cause of the Samsung refrigerator error code and get troubleshooting advice to clear the code.
The refrigerator may work properly even though the control displays an error code. A power outage can sometimes cause the control to detect a problem and display a code. The control may continue to display the code even if the component failure no longer exists. To reset the display so it shows freezer and refrigerator temperatures, press and hold the Energy Saver and Lighting buttons simultaneously for 8 seconds. The Samsung refrigerator code will disappear and the display will resume normal operations.
If the code reappears on the display, follow the troubleshooting steps in the chart below to fix the problem being detected and clear the code.
If you cleared an error code from the display and encounter cooling problems in the refrigerator, the component problem that caused the code likely still exists even though you cleared the code. You can redisplay a detected error code by pressing and holding the Energy Saver and Lighting buttons simultaneously for 8 seconds. The display will chime and display the code for 30 seconds. The display will then revert back to showing freezer and refrigerator temperatures.
Follow the troubleshooting steps described for the code to fix the component failure and clear the code.

| Error Code | Condition | DIY Advice |
|---|---|---|
| 1 E | Freezer temperature sensor failure |
Check/Repair
Unplug the refrigerator and check the wire harness connection on the freezer temperature sensor. Reconnect the wire harness if it’s loose. If the wire harness connection is okay, check sensor resistance using a multimeter. The meter should measure about 5,600 ohms if the sensor temperature is 72 degrees (room temperature), 13,290 ohms at 32 degrees and 29,000 at 0 degrees. Replace the temperature sensor if resistance is off by more than 10 percent. If sensor resistance is okay, reinstall the temperature sensor and check the sensor’s wire harness connections to the electronic control board (red wire on CN30 and gray wire on CN76). Reconnect the wires if loose. If the wire connections are okay, disconnect the sensor wires from the electronic control board and measure resistance through the sensor’s wires. The meter should read the same resistance as for the temperature sensor. If the meter measures correct sensor resistance through the wires, you’ll likely need to replace the electronic control board because it’s not accurately detecting sensor resistance. Find and repair the sensor wiring failure if the meter measures infinite resistance through the sensor wires.
