Thermador Oven Error Code F34

How to fix Thermador oven error code F34

If your oven displays error code F34, this usually indicates a problem with the top oven cooling fan or a fault in the upper oven airflow system. This error can occur for various reasons, including issues with the cooling fan motor, blockages in the airflow path, or faulty components in the airflow system.

How to resolve the error code F34

In the event of a malfunction of the top oven cooling fan:

• Check fan operation. If you don’t hear the fan running, inspect the fan blades, motor, and wiring for any visible damage or disconnection.
• Inspect wiring. Examine the wiring connections to ensure there are no loose or damaged wires. Repair or replace as needed.
• Replace the fan motor. If the fan is still not working after checking the above, it may be necessary to replace the fan motor. A professional should do this to ensure proper installation.

In the event of airflow error:

• Check fan operation. If the fan is running but the error persists, the issue may lie with the air switch.
• Replace the air switch. The air switch is responsible for detecting proper airflow. If it’s faulty, it needs to be replaced by a professional technician to restore normal oven function.
