LG Heat Pump Error Code E413

E413 indicates an outdoor unit overload protection control error on circuit 3. The system has detected that the outdoor unit, most likely the compressor or a related motor component, is operating outside safe current or thermal limits. LG's control system triggers this code to shut down operation and protect the hardware from damage. A technician should inspect the outdoor unit before attempting to restart the system.

No, you should not continue operating the system while this error is active. The E413 code means the outdoor unit's overload protection has activated specifically to prevent hardware damage. Running the unit in this state risks permanent compressor failure, which is one of the most expensive repairs on a heat pump system. Leave the system off until the cause is identified and corrected.

Repair costs vary widely depending on the root cause. A coil cleaning or electrical connection repair might cost between $100 and $300 in labor. A refrigerant recharge typically runs $150 to $400 depending on refrigerant type and quantity. Outdoor fan motor replacement generally falls in the $250 to $600 range including parts and labor. Compressor replacement is the most expensive outcome, often ranging from $1,000 to $2,500 or more depending on the unit size and model.

Some basic checks are within reach of a capable DIYer, such as clearing debris from around the outdoor coil, straightening bent coil fins, and verifying the outdoor fan is spinning freely. However, diagnosing refrigerant charge problems, measuring compressor amp draw, and replacing components like the compressor or fan motor require specialized tools and EPA certification for refrigerant handling. Most cases of E413 will need a qualified HVAC technician.

A power reset may temporarily clear the error and allow the system to restart, but the code will return if the underlying problem has not been fixed. Repeatedly resetting the unit without addressing the root cause can accelerate wear on the compressor and other outdoor components. Treat the reset as a diagnostic tool only, not a repair.
