Sub-Zero Refrigerator Error Code 15 8 01

Error code 15 8 01 means the ice maker relay on the control board is stuck in the closed position, delivering constant power to the ice maker. Normally this relay cycles on and off to control ice production. When it fails closed, the ice maker runs continuously without the control board being able to stop it. Resolving this error requires replacing the control board.

No, a reset will not clear error code 15 8 01. The underlying cause is a physical hardware failure: the relay contacts are mechanically welded shut and cannot be restored by cycling power. The control board must be replaced to resolve the fault.

Repair costs for this error vary based on parts and labor rates in your area. Control board replacement on a Sub-Zero refrigerator typically falls in the range of $400 to $900 or more when accounting for the part and professional labor. Sub-Zero parts tend to be priced at a premium compared to standard appliance brands, so obtaining a quote from an authorized service provider before proceeding is recommended.

The fix for this error is replacing the main control board, since the failed relay is not a separately replaceable component. A knowledgeable DIYer comfortable with disassembling appliance panels and working with electrical components may be able to perform this replacement. However, it is important to also inspect the ice maker wiring for any shorts that may have caused the relay to fail before installing a new board. If you are unsure, a certified appliance technician is recommended.

Running the refrigerator with this error active means the ice maker is receiving continuous power, which can lead to overfilling of the ice bin, excess frost buildup in the freezer, and additional wear on the ice maker components. It is advisable to turn the ice maker off manually or disconnect it until the control board is replaced to prevent further issues.
