What the 4-1-1 error code actually means

Your Thermador refrigerator is displaying an error because the ice maker has detected an internal problem it cannot fix on its own. This means something inside the ice maker unit has failed, and it will not be able to produce ice until the issue is resolved. Turning the refrigerator off and back on may clear the error if it was a temporary glitch, but if the code comes back, the ice maker will need to be replaced.

Questions people ask about 4-1-1

What does 4-1-1 mean on a Thermador refrigerator?
The 4-1-1 error code on a Thermador refrigerator indicates an internal ice maker fault. This means the ice maker assembly has detected a failure within its own components, such as the harvest motor, internal thermostat, or control module. The rest of the refrigerator's cooling system is not affected by this fault. Ice production will stop until the issue is resolved.
How do I fix a 4-1-1 error on a Thermador refrigerator?
Start by turning the refrigerator off and back on to perform a power cycle reset. If the error code returns, the ice maker assembly requires replacement, as the fault is internal to the unit and not serviceable at the component level. Replacing the ice maker assembly is the repair procedure specified for a persistent 4-1-1 fault.
How much does it cost to fix a Thermador refrigerator 4-1-1 error?
If a power cycle clears the error, there is no parts cost involved. If the ice maker assembly needs replacement, parts alone typically range from $150 to $400 or more depending on the specific Thermador model, and professional labor can add $100 to $250 to that total. Getting a quote from an authorized service technician before proceeding is recommended.
Will resetting the refrigerator clear the 4-1-1 error code?
A power cycle reset is always the first step and can clear the code if the fault was caused by a temporary electrical glitch. To reset, switch the refrigerator off, wait a minute, and turn it back on. If the 4-1-1 code reappears after the reset, the fault is considered persistent and the ice maker assembly will need to be replaced.
Is it safe to keep using my Thermador refrigerator with a 4-1-1 error?
Yes, a 4-1-1 fault affects only the ice maker and does not impact the refrigerator or freezer compartments. Your food will remain safely cooled while this error is present. However, the ice maker will not produce ice until it is repaired or replaced.
