Daewoo Refrigerator Error Code R1

The R1 error code means the primary refrigerator compartment temperature sensor has a malfunction, caused by either a short circuit or a wire disconnection. The control board cannot get a valid temperature reading from this sensor. Fortunately, the refrigerator will continue operating using the R2 backup sensor, but the R1 sensor or its wiring will need to be repaired or replaced.

Yes, the refrigerator is designed to continue operating on the R2 backup sensor when R1 fails, so your food should remain at safe temperatures in the short term. However, running on a backup sensor is not a permanent solution, as the system's temperature regulation may be less precise. The R1 sensor should be repaired as soon as practical to restore full functionality.

A power reset may temporarily clear the error code display, but the code will return if the underlying fault with the R1 sensor or its wiring has not been corrected. Resetting is useful for confirming whether the fault is intermittent, but it is not a repair. The sensor circuit must be inspected and the short circuit or disconnection resolved before the error will stay cleared.

If the cause is a loose connector, a knowledgeable DIYer can inspect the wiring harness and reseat the connection to resolve the error. However, if the sensor itself has failed or a wire is broken inside the harness, replacing the component typically requires sourcing the correct part and some comfort with appliance wiring. When in doubt, a qualified appliance technician should handle the repair.

If the fix involves simply reseating a loose connector, there may be no parts cost at all, only a service call fee if a technician is involved. Replacing the R1 temperature sensor itself typically costs somewhere in the range of $50 to $150 for parts and labor combined, depending on your location and the technician's rates. A wiring harness repair or replacement can push costs higher.
