Thermador Refrigerator Error Code 3-3-5

The 3-3-5 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 or control logic. The fault is specific to the ice maker unit itself, not to external systems like water supply lines or refrigerator temperature. If a power cycle does not clear the code, the ice maker unit requires replacement.

Start by switching the refrigerator off and on to perform a power cycle and allow the ice maker to reinitialize. If the 3-3-5 code reappears, the ice maker assembly has an internal fault that cannot be repaired at the component level and the full unit must be replaced. A qualified appliance technician can confirm the diagnosis and install the replacement ice maker.

Repair costs vary depending on the specific model and local labor rates. The ice maker assembly itself typically ranges from around 100 to 300 dollars for parts, and professional installation labor can add another 100 to 200 dollars depending on your area. Getting a quote from a certified technician before proceeding is advisable to confirm the part cost for your specific model.

A power cycle, turning the refrigerator off and then back on, is the recommended first step and may clear the code if it was caused by a transient glitch. However, if the 3-3-5 code returns after the reset, the fault is persistent and a reset will not resolve it. In that case, the ice maker assembly must be replaced to eliminate the fault.

The 3-3-5 fault is specific to the ice maker and does not affect the main refrigeration or freezing functions of the appliance. The refrigerator will continue to cool normally. The fault does not present a safety hazard, but it does mean the ice maker will not produce ice until the issue is resolved.
