What 3-2-2 means on a Thermador refrigerator
Error code 3-2-2 on a Thermador refrigerator indicates a fault within the icemaker motor circuit. The control board has detected that the icemaker motor is not operating within expected parameters, either failing to respond to drive signals or drawing incorrect current during its harvest cycle. The icemaker motor drives the ejector blades that push formed ice cubes out of the mold tray and rotates the mechanism through its harvest sequence. When this motor fails or becomes electrically open or shorted, the control system flags the 3-2-2 code and halts icemaker operation to prevent further damage.
The root cause is typically internal motor failure within the icemaker assembly itself. Thermador's diagnostic approach confirms this by noting that the motor is not a separately replaceable component. This means the motor is integrated into the icemaker module, and individual motor replacement is not a supported repair path. If the fault code clears after a power cycle, it may indicate a transient electrical issue such as a voltage spike or temporary communication fault. However, if the 3-2-2 code returns after switching the appliance off and back on, the icemaker assembly requires full replacement. Attempting to operate the unit with a confirmed motor fault will result in continued icemaking failure and potential ice jam buildup inside the unit.

Common causes of 3-2-2
- 01
Failed icemaker motor (internal)
Part replacementThe motor integrated within the icemaker module has burned out or seized, preventing the ejector mechanism from completing its harvest cycle. This is the most likely cause when the 3-2-2 code persists after a power cycle.
- 02
Transient electrical fault or voltage spike
Wiring / connectionA brief power fluctuation can cause the control board to register a false motor fault. If the code clears after cycling power and does not return, no part replacement may be needed.
- 03
Ice jam or mechanical obstruction in ejector
Wiring / connectionAn ice jam blocking the ejector blades can prevent the motor from turning, causing the control board to detect a motor fault. Inspecting the icemaker tray for lodged ice cubes before replacing the unit is a reasonable first step.
- 04
Wiring harness or connector issue
Wiring / connectionA loose, corroded, or damaged connector between the icemaker assembly and the control board can interrupt motor signals and trigger this code. Inspect the wiring harness at the icemaker plug for visible damage or poor seating.
- 05
Defective icemaker control module
Part replacementIn some cases the onboard circuitry within the icemaker assembly that drives the motor can fail, producing a motor fault code even if the motor windings are intact. Since the motor is not individually replaceable, the full assembly still requires replacement.
