Thermador Refrigerator Error Code 3-3-3

The 3-3-3 error code on a Thermador refrigerator indicates an internal ice maker fault. This means the ice maker assembly has detected a failure within its internal components, such as the control module, harvest motor, heater, or internal thermostat. The ice maker will typically stop producing ice while this fault is active. A power cycle can sometimes clear the code if the cause was a transient glitch, but a recurring code requires ice maker replacement.

Start by switching the refrigerator off, waiting about one minute, and turning it back on. If the code clears and does not return, no further action is needed. If the 3-3-3 code comes back after the power cycle, the ice maker assembly itself has an internal hardware failure and should be replaced. Because the faulty components are integrated into the ice maker unit, replacing the full assembly is the standard repair approach.

If the repair requires replacing the ice maker assembly, parts costs typically range from around $80 to $250 or more depending on the specific model, with labor costs adding $100 to $200 if a technician performs the repair. If a simple power cycle clears the code, there is no parts cost involved. Getting a model-specific parts quote before scheduling a service call is recommended to understand the total cost.

A reset, meaning turning the refrigerator off and back on, is the recommended first step and can clear the code if it was caused by a temporary electrical issue. However, if the 3-3-3 code reappears after the power cycle, the fault is persistent and a reset will not permanently resolve it. In that case, the ice maker assembly needs to be replaced to eliminate the code.

The 3-3-3 fault is limited to the ice maker system and does not affect the refrigerator or freezer cooling functions. Your food will remain safely refrigerated and frozen while this code is present. The only consequence is that the ice maker will not produce ice until the fault is resolved.
