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

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 (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.

Check 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. If the ice maker wiring connections to the electronic control board are okay, replace the ice maker.
