RF23HCEDBSR. The meter should measure about 120 ohms of resistance.
Check the refrigerator evaporator fan wiring connections (orange wire on pin 4, gray wire on pin 1 and red wire on pin 8) on the CN76 electronic control board connector. Reconnect any loose wires. Using a multimeter, measure resistance through the yellow and pink wires on the CN79 plug. The Samsung secret codes are used by developers and designers to access hidden settings and features. FRENCH DOOR REFRIGERATOR.

If sensor resistance is okay, reinstall the temperature sensor and check the sensor's wire harness connections to the electronic control board (orange wire on CN30 and gray wire on CN76). If the meter measures infinite resistance, check resistance directly at the ice maker fill tube heater.

If the wiring connections are okay, replace the refrigerator evaporator fan.Unplug the refrigerator and check the wire harness connections on the condenser fan. 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. Help. Power on, have reset on the display and cut power for 2 minutes to …
The meter should measure about 5,600 ohms if the sensor temperature is 72 degrees (room temperature), 13,290 ohms at 32 degrees and 11,700 at 37 degrees. If the meter measures infinite resistance or near 0 resistance through the yellow and gray humidity sensor wires, replace the humidity sensor. If freezer temperature is near 0 degrees (normal operating temperature), unplug the refrigerator and check the ice maker wire harness connection. 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). 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. If the refrigerator evaporator defrost temperature sensor is good, then you may need to replace the electronic control board because the board isn't sending electric current to the defrost heater. Find and repair the sensor wiring failure if the meter measures infinite resistance through the sensor wires.Freezer evaporator defrost temperature sensor failureUnplug the refrigerator and check the wire harness connection on the freezer evaporator defrost temperature sensor. 21: Freezer fan error: The voltage of the MAIN PCB CN74 1↔4: should be between 7V~12V. Thank you ! Replace the sensor if it's bad. Cause and reason: Is the power off or the power unplugged? Then I got an error code that said PC - 1392511 Reconnect the wires if loose. The meter should read the same resistance as for the temperature sensor. Reconnect the wire harness if it's loose. The meter should measure around 102 ohms. It’s easy to replace a worn or torn gasket.Use the advice and tips in these articles and videos to get the most out of your refrigerator.Learn what to check if the inside of your fridge is wayyyy too warm.Find out about the new refrigerator sounds you might not be aware of.See how the different components in your refrigerator work together to cool your food.Freezer temperature sensor, Electronic control boardRefrigerator compartment temperature sensor, Electronic control boardFreezer evaporator defrost temperature sensor, Electronic control boardRefrigerator evaporator defrost temperature sensor, Electronic control boardAmbient temperature sensor, Electronic control boardPantry drawer temperature sensor, Electronic control boardIce room temperature sensor, Electronic control boardFreezer defrost heater, Freezer defrost bi-metal thermostat, Freezer evaporator defrost temperature sensor, Electronic control boardRefrigerator defrost heater, Refrigerator defrost bi-metal thermostat, Refrigerator evaporator defrost temperature sensor, Electronic control boardPantry drawer air damper motor, Electronic control boardIce maker fill tube and heater, Electronic control board© 2020 Transform SR Brands LLC. If the defrost heater and bi-metal thermostat are both okay, find and repair the wiring break in the defrost circuit that is preventing the heater from getting electrical current.Check freezer temperature because the ice maker won't cycle if freezer temperature is above 15 degrees. If the wire harness connection is okay, check sensor resistance using a multimeter. Replace the ice room temperature sensor if resistance is off by more than 10 percent. If the ice room temperature sensor wire harness connection is okay, check the ice room temperature sensor resistance using a multimeter. The control may continue to display the code even if the component failure no longer exists. If the meter measures infinite resistance through the air damper heater wires, find and repair the wiring break in the damper heater wires.Unplug the refrigerator and remove the electronic control board cover. If the wire harness connection is okay, check sensor resistance using a multimeter. If the wire connections are okay, disconnect the sensor wires from the electronic control board and measure resistance through the sensor's wires. Replace the temperature sensor if resistance is off by more than 10 percent. It took me a while to get 'Safe Mode' to kick in (it was sucessful when I pressed the four-square Windows key, and R at the same time, then put "msconfig" into a command line). If the board is at fault, follow these steps to replace it yourself.Replace the water valve that feeds water to the ice maker and water dispenser if it no longer controls the flow of water.The door gasket seals the gap around the door to keep the cold air in and the warm air out. Find and repair the sensor wiring failure if the meter measures infinite resistance through the sensor wires.Refrigerator pantry drawer temperature sensor failureUnplug the refrigerator and check the wire harness connection on the pantry drawer temperature sensor in the refrigerator compartment. If the wire harness connection is okay, check sensor resistance using a multimeter. Check for evaporator frost and ice buildup that can block fan blade rotation.
