Thermador Refrigerator Error Code 3-1-1

The 3-1-1 code on a Thermador refrigerator indicates an internal ice maker fault. The refrigerator's diagnostic system has detected a failure within the ice maker assembly itself, rather than in an external sensor or connected component. The first step is to turn the appliance off and back on to rule out a transient glitch. If the code returns after the reset, the ice maker unit needs to be replaced.

Start by switching the refrigerator off and on to see if the code clears. If it does not, the ice maker assembly needs to be replaced as a unit. Before ordering a replacement, check the ice maker area for visible ice jams or mechanical obstructions, as clearing a jam may resolve the issue without part replacement. If no jam is found and the code persists, full module replacement is the correct repair.

If the reset does not clear the code and the ice maker module needs replacement, parts costs typically range from $80 to $250 or more depending on the specific model, with labor adding $100 to $300 if a technician is hired. Total repair costs generally fall in the range of $150 to $500 for a professional repair. Costs can vary based on your location and the specific Thermador model involved.

A reset can clear the 3-1-1 code if the fault was caused by a temporary electrical fluctuation or a one-time software error. Turn the refrigerator off, wait a minute, and power it back on. If the code reappears after the reset, the fault is persistent and the ice maker module will need to be replaced, as a reset will not resolve a hardware failure inside the unit.

The 3-1-1 fault is specific to the ice maker and does not affect the refrigerator's cooling system or food safety. Your refrigerator will continue to maintain temperature and preserve food normally while this code is active. The only function impacted is ice production. There is no safety hazard associated with this fault code, so there is no urgency to stop using the refrigerator.
