Daewoo Refrigerator Error Code R2

The R2 error code indicates a malfunction in the second refrigerator compartment temperature sensor, caused by either a short circuit or a wire disconnection in the sensor circuit. When this fault is active, the low cooling prevention function tied to that sensor is disabled. This means the refrigerator cannot reliably protect the compartment from temperature irregularities. The sensor and its wiring harness should be inspected promptly.

Using the refrigerator with an active R2 error carries some risk because the low cooling prevention function tied to the R2 sensor is disabled. This means the appliance may not maintain accurate temperatures in the fresh food compartment, which could affect food safety. It is advisable to address the fault as soon as possible and monitor compartment temperatures with an independent thermometer in the meantime.

Repair costs vary depending on the root cause. Replacement temperature sensors are generally inexpensive, typically in the range of $10 to $40 for the part alone. If a wiring harness or control board replacement is needed, costs can rise to $80 to $250 or more including labor. A professional diagnostic visit typically adds $60 to $120 before any parts are factored in.

A knowledgeable DIYer can diagnose this error by visually inspecting the R2 sensor wiring for damage and testing continuity with a multimeter. If the issue is a loose connector, it can often be reseated without special tools. Replacing the sensor or wiring harness requires basic appliance repair skills and sourcing the correct replacement part for your model.

A power reset may temporarily clear the error display, but the code will return if the underlying fault in the R2 sensor circuit is still present. The sensor or wiring issue must be physically diagnosed and repaired before the error will stay cleared. Resetting without repairing does not restore the disabled low cooling prevention function.
