Thermador Refrigerator Error Code 2-3-1

Error code 2-3-1 on a Thermador refrigerator indicates an internal ice maker fault. This means the ice maker module has detected a failure within its own internal components or control logic. Ice production will not occur while this fault is active. The primary recommended repair is replacement of the ice maker assembly.

Error code 2-3-1 is not a safety hazard. It is limited to the ice maker system and does not affect the refrigerator's ability to cool food or the freezer's normal operation. You can continue using the refrigerator while scheduling the repair, though ice production will be inactive.

A power reset may temporarily clear the fault code display, but it will not resolve the underlying internal ice maker fault. If the ice maker module has a failed component, the error code will return once the refrigerator restores power and the ice maker attempts to run its cycle. A reset is only useful to confirm whether the fault is intermittent or persistent.

A homeowner or experienced DIYer can begin by checking for ice or debris lodged in the ejector mechanism and confirming the freezer is at the correct temperature. If those checks do not resolve the fault, replacing the ice maker assembly is the next step. Ice maker replacement is a moderate-difficulty repair that involves disconnecting wiring harnesses and removing mounting hardware. If you are not comfortable working inside a refrigerator, a technician is recommended.

If the ice maker assembly requires replacement, the part itself typically costs in the range of $150 to $400 depending on the specific Thermador model. If a technician is hired for the repair, labor charges generally add $100 to $250 to the total cost. Prices can vary based on your region and service provider.
