Sub-Zero Wine Storage Error Code 15 2 01

Error code 15 2 01 means the Zone 2 compressor relay is stuck in the closed position, causing 120V to be supplied to the Zone 2 compressor continuously. This prevents normal temperature cycling in that zone. The control board is the source of the fault and must be replaced to resolve it.

Continued use is not recommended. With the compressor running constantly, Zone 2 will overcool and lose all temperature regulation, which can damage wine stored in that zone. There is also added wear on the compressor from continuous operation. The unit should be inspected and repaired promptly.

Repair costs depend on parts and labor rates in your area. A replacement control board for a Sub-Zero wine storage unit typically ranges from several hundred to over a thousand dollars for the part alone, with additional labor costs on top of that. Getting a quote from an authorized Sub-Zero service provider will give you the most accurate estimate for your specific model.

Resolving this code requires replacing the control board, which involves working with 120V wiring and board-level components. While a knowledgeable DIYer with experience in appliance repair may be able to complete the swap, the job is generally better suited to a certified technician to ensure safe handling of line voltage and correct board installation.

No. This error reflects a hardware failure in the control board relay, not a temporary software or sensor glitch. Resetting the unit will not restore proper relay function or clear the fault. The control board must be replaced before the error will resolve.
