LG Refrigerator Error Code R5

The R5 code indicates that the freezer compartment evaporator fan motor has failed or is not sending a signal back to the control board. The refrigerator's compressor and defrost heater continue to operate normally, but without the fan running, cold air cannot circulate through the freezer or fresh food sections. The motor may be mechanically locked, electrically failed, or there may be a wiring issue in the fan circuit.

It is not recommended to continue using the refrigerator normally with an active R5 error. Because the freezer fan is not circulating air, food temperatures in both the freezer and fresh food compartments will rise, creating a food safety risk. The compressor running without airflow can also cause it to work harder than intended. The issue should be diagnosed and resolved as soon as possible.

Unplugging the refrigerator and restoring power may temporarily clear the R5 code from the display, but the error will return if the underlying cause has not been corrected. A reset should not be used as a substitute for diagnosis. If the fan motor is locked due to ice and the ice is fully melted before restarting, the reset may result in a lasting fix, but an electrically failed motor or wiring fault will trigger R5 again once the unit restarts.

Some causes of the R5 error are DIY-friendly, such as clearing ice that is blocking the fan blade or reseating a loose wiring connector. You can perform a manual defrost by unplugging the refrigerator for 24 to 48 hours to melt any ice obstruction and then check if the error clears. However, if the fan motor itself has failed electrically or the control board is at fault, replacing those components requires moderate technical skill and the correct replacement part for your model.

Repair costs vary depending on the root cause. A replacement evaporator fan motor for an LG refrigerator typically costs between $30 and $100 for the part alone, and professional labor can add $100 to $200 or more depending on your location and the technician. If the main control board is at fault, parts alone can range from $100 to $300 or higher. If ice obstruction is the only cause, the repair may cost nothing beyond your time.
