Thermador Refrigerator Error Code 1-3-1

Error code 1-3-1 means the icemaker's ice production cycle was interrupted before it could complete. The icemaker goes through a sequence of filling with water, freezing, and harvesting ice, and this fault triggers when that sequence is stopped partway through. The most common cause is a mechanical blockage preventing the ice tray from rotating during the harvest phase. Running the icemaker self-test to observe tray rotation is the recommended first diagnostic step.

Yes, the 1-3-1 code is specific to the icemaker system and does not indicate a problem with the refrigerator or freezer compartments themselves. Your refrigerator will continue cooling and preserving food normally. However, the icemaker will not produce ice until the fault is resolved, so you should address the issue if you rely on the icemaker.

Repair costs vary depending on the cause. If the issue is simply a mechanical blockage, clearing it yourself costs nothing. Replacing a water inlet valve typically runs between 75 and 200 dollars in parts, while an ice tray motor or icemaker control module can range from 100 to 350 dollars in parts before labor. Professional service calls for icemaker diagnostics and repair generally add 100 to 250 dollars in labor depending on your location and the complexity of the repair.

Start by running the icemaker self-test and watching whether the ice tray completes a full rotation. If it does not rotate, check for ice buildup or obstructions around the tray and clear them. If the tray is mechanically free but still does not move, the tray motor or icemaker control module may need to be replaced. Also verify that the water inlet valve is functioning and that the freezer is holding proper temperature.

A reset may temporarily clear the code, but if the underlying problem is not corrected, the fault will return once the icemaker attempts another production cycle. Resetting is useful for confirming whether the issue was a one-time occurrence, such as a temporary blockage that has since cleared. For persistent faults, a full diagnostic inspection of the tray motor, water inlet valve, and control module is necessary.
