Samsung RF265/RS267 models 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 (gray wire on pin 4 and yellow wire on pin 5 of CN40). 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.

Unplug the refrigerator and remove the electronic control board cover. Using a multimeter, check the resistance through the brown wire and the orange wire on the CN70 control board connector. If the meter measures about 66 ohms, then the defrost heater, bi-metal thermostat and thermal fuse are good. Check the freezer evaporator defrost temperature sensor as described in troubleshooting for the 4 E error code. Replace the freezer evaporator defrost temperature sensor if it’s bad. If the 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. If the meter measures infinite resistance through the brown and orange wires on CN70, then a wiring break or a failed component in the defrost circuit is preventing the defrost system from heating. First, check resistance through the defrost heater. The meter should measure about 66 ohms through the defrost heater. Replace the defrost heater if the meter measures infinite resistance through the defrost heater. If the defrost heater is good, check the resistance through the defrost bi-metal thermostat. The meter should measure near 0 ohms of resistance through the defrost bi-metal thermostat. Replace the bi-metal thermostat if the meter measures infinite resistance. If the defrost heater and bi-metal thermostat are both okay, check resistance through the thermal fuse. The meter should measure near 0 ohms of resistance through the thermal fuse. Replace the thermal fuse if the meter measure infinite resistance. If the defrost heater, bi-metal thermostat and thermal fuse are all good, find and repair the wiring break in the defrost circuit that’s preventing the defrost heater from getting electrical current through the defrost system circuit and causing the infinite resistance reading through the brown and orange wires on CN70.
