Samsung RS25H model side-by-side refrigerator error codes:

Reference Model: RS25H

These error code explanations can help you diagnose a problem with Samsung your RS25H side-by-side refrigerators.

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 1 minute. 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.


Code Meaning Possible Cause Possible Parts
1 E Freezer temperature sensor failure 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 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 (sky blue 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 Freezer temperature sensor, Electronic control board

24 E Freezer evaporator defrost system failure Unplug the refrigerator and check the wiring connection of the freezer defrost heater assembly to the electronic control board (brown wire on CN70). Reconnect the wire if it's loose. If that wiring connection is okay, check the freezer evaporator defrost temperature sensor as described in troubleshooting for the 4 E error code. Replace the sensor if its resistance is off by more than 10 percent because a faulty defrost temperature sensor can prevent the defrost system from working. If the sensor is good, check resistance through the defrost heater using a multimeter. The meter should measure about 66 ohms of resistance through the defrost heater. Replace the defrost heater if the meter measures infinite resistance. If the defrost heater is good, measure resistance through the defrost bi-metal thermostat.
