Samsung Refrigerator Error Code r-SE

The r-SE code indicates a problem with the R-Room sensor, the thermistor that measures temperature inside the refrigerator compartment. The control board has detected a reading below -50 degrees Celsius (OPEN circuit) or above +50 degrees Celsius (SHORT circuit), both of which are outside the valid range. This typically points to a failed sensor, damaged wiring, or a loose connector.

Start by cycling the power off and on to rule out a transient fault. If the code returns, inspect the wiring harness and connector running to the R-Room sensor inside the refrigerator compartment for damage, breaks, or corrosion. You can test the sensor itself with a multimeter to check its resistance. If the sensor is confirmed faulty, it will need to be replaced.

If only the R-Room sensor needs replacement, parts typically range from roughly 15 to 50 dollars depending on the specific model, and the repair is relatively straightforward for someone comfortable with basic appliance work. If a professional technician is needed, total repair costs including labor generally fall in the range of 100 to 250 dollars. A failed main control board is the most expensive scenario, with parts and labor potentially reaching 200 to 400 dollars or more.

A power reset is the recommended first step and can clear the code if it was caused by a temporary signal glitch or a loose connection. Turn the main power off, wait at least one minute, then turn it back on and observe the display. If the code returns after the reset, a physical inspection of the sensor and wiring is needed.

The error code itself is not a safety hazard, but it does mean the refrigerator may not be regulating temperature correctly inside the fresh food compartment. If the fridge is not cooling properly as a result of this fault, perishable food could spoil. It is best to address the code promptly and monitor the actual temperature inside the fridge in the meantime.
