Samsung RS30 and RSG307 models side-by-side refrigerator error codes

These error code explanations can help you diagnose a problem with Samsung RS30 and RSG307 side-by-side refrigerators. For how-to information, visit the PartsDirect repair help section, which includes DIY help for major appliances, lawn and garden equipment, garage door openers, vacuum cleaners and more. Search for your model number to find a complete list of replacement parts for your refrigerator.

This type of refrigerator displays 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 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 error 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 CodeConditionDIY Advice
1 EFreezer temperature sensor failureCheck/RepairUnplug 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 ohms 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 (yellow wire and gray wire on CN30). 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.How-to helpHow to replace a refrigerator thermistorPossible partsFreezer temperature sensor, Electronic control board

26 EIce maker failureCheck/RepairCheck freezer temperature because the ice maker won’t cycle if freezer temperature is above 15 degrees. If freezer temperature is above 15 degrees, check the freezer door gasket and replace the gasket if it’s torn or damaged, allowing warm air to leak into the freezer and preventing the ice maker from cycling. If freezer temperature is near 0 degrees (normal operating temperature), unplug the refrigerator and check the ice maker wire harness connection. Reconnect the ice maker wire harness plug if it’s loose. If the wire harness connection is okay, check the ice maker wire harness connections on the electronic control board (CN90 connector and the black and gray wires on CN51). Reconnect any loose wires.

The air damper heater wires are included in the air damper motor wire harness. Reconnect the air damper motor wire harness if it’s loose. Using a multimeter, check resistance through the air damper heater (connected to the black and brown wires). The meter should measure about 135 ohms through the air damper heater. Replace the pantry drawer air damper motor if the meter measures infinite resistance through the air damper heater. The air damper heater is included with the pantry drawer air damper motor and isn’t available as a separate component. If the meter measures near 135 ohms through the damper heater, plug the pantry drawer air damper motor wiring harness back in and check the damper heater wiring connections to the electronic control board (black and brown wires on CN77). Reconnect the wires if they’re loose. If the wiring connections are okay, check resistance through the black and brown air damper heater wires. If the meter measures near 135 ohms through the damper heater wires, replace the electronic control board because it isn’t sending voltage to the air damper heater or the control board isn’t detecting the feedback signal from the air damper heater accurately. If the meter measures infinite resistance through the air damper heater wires, find and repair the wiring break in the air damper heater wires.Possible partsPantry drawer air damper motor, Electronic control board
33 EIce maker fill tube heater failureCheck/RepairUnplug the refrigerator and remove the electronic control board cover. Disconnect the CN79 plug from the control board. Using a multimeter, measure resistance through the yellow and pink wires on the CN79 plug. The yellow and pink wires connect to the ice maker fill tube heater. The meter should measure around 102 ohms. If the meter measures correct resistance, replace the electronic control board because it’s not detecting the correct resistance through the ice maker fill tube heater circuit. If the meter measures infinite resistance, check resistance directly at the ice maker fill tube heater. Replace the ice maker fill tube and heater if the meter measures infinite resistance directly at the ice maker fill tube heater. If the meter measures around 102 ohms directly at the fill tube heater, find and repair the wiring break between the ice maker fill tube heater and the electronic control board.Possible partsIce maker fill tube and heater, Electronic control board
