Samsung RS25H model side-by-side refrigerator error codes

Unplug the refrigerator and check the wire harness connection on the refrigerator compartment 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 11,700 ohms at 37 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 (black 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.

If humidity sensor resistance through the yellow and gray wires is around 50 ohms, plug the humidity sensor back into the wire harness and check resistance through the brown and gray wires on CN30 of the electronic control board. If the meter measures around 50 ohms through the brown and gray wires that connect the humidity sensor to the control board, then you'll likely need to replace the electronic control board because it isn't accurately detecting humidity sensor resistance. Find and repair the humidity sensor wiring failure if the meter measures incorrect resistance through the brown and gray humidity sensor wires that connect to the control board.
