Sub-Zero Refrigerator Error Code 60 6 60

Error code 60 6 60 means the refrigerator's control system attempted to run the compressor but detected no electrical load present. This indicates a break in the compressor circuit, which can be caused by a failed starting relay, open compressor windings, or a wiring fault. The refrigerator will not cool properly while this fault is active.

When this error is active, the compressor is not running, which means the unit is not maintaining safe food storage temperatures. You should transfer perishable food to another refrigerator as soon as possible and arrange for service promptly. Continuing to store food in a unit displaying this fault risks food spoilage.

A reset may temporarily clear the error code from the display, but the code will return if the underlying electrical fault has not been corrected. The control board monitors the compressor circuit continuously, and any persistent open load condition will trigger the fault again on the next compressor start attempt. The root cause must be diagnosed and repaired for the error to stay cleared.

Some portions of the diagnosis are accessible to a knowledgeable DIYer, such as inspecting wiring connections and testing the starting relay by checking for a rattle or testing continuity. However, replacing a compressor requires recovering refrigerant, which requires EPA certification and specialized equipment. If the compressor itself has failed, professional service is necessary.

Repair costs vary significantly depending on the root cause. A starting relay replacement is a relatively inexpensive repair, typically in the range of $100 to $300 including labor. A compressor replacement on a Sub-Zero unit is a major repair that can range from $700 to $2,000 or more depending on the model and labor rates in your area. A control board replacement falls somewhere between those two extremes.
