What the -- error code actually means

Your Sub-Zero refrigerator has been put into shutdown mode, which means it has stopped cooling but the lights and door alarm are still working. This is not a breakdown; it is a mode that can be turned on intentionally or accidentally through the control panel. Simply press the COLDER key to restart normal operation.

Questions people ask about --

What does -- mean on a Sub-Zero refrigerator?
The -- display means the refrigerator is in shutdown mode. All cooling functions, including the compressor and fans, are suspended. Only the interior lights and door alarm remain active. This is a deliberate operational state, not an error or mechanical failure.
Is it safe to leave food in my Sub-Zero while it shows --?
Shutdown mode suspends all cooling, so food safety depends on how long the unit has been in this state. If the unit was in shutdown mode for only a short time, food is likely safe. If it has been several hours or longer, check food temperatures carefully, as perishables may have risen above safe storage levels.
How much does it cost to repair a Sub-Zero refrigerator that keeps entering shutdown mode?
If the issue is a stuck or faulty keypad, replacement parts and labor typically range from $150 to $400 depending on the model and service location. If the main control board is at fault, repair costs can range from $300 to $700 or more. A service call to diagnose the root cause usually costs between $100 and $200.
How do I fix the -- shutdown mode on my Sub-Zero refrigerator?
Press the COLDER key on the control panel to exit shutdown mode and restart normal refrigeration operation. The display should return to showing temperature settings and the compressor should resume shortly after. If the unit enters shutdown mode again on its own, inspect the keypad for stuck keys.
Will resetting my Sub-Zero refrigerator clear the -- code?
Pressing the COLDER key is the correct way to exit shutdown mode and does not require a full power reset. If you do power cycle the unit, it may or may not exit shutdown mode depending on how the mode was originally triggered. Using the COLDER key directly is the recommended first step.
