Thermador Oven Error Code F34 – Common Causes & Solutions

Error code F34 indicates that your Thermador oven’s top cooling fan air switch is undefined. There are many reasons why this error occurs, but Jacob Dillard, an engineer at Appliance Repair Expert, will try to give us the answers.

Reason #1. Problem with the air switch

Thermador oven error codes are not a good sign, but in this case, your problem is caused by the faulty air switch. To solve the issue, replace the air switch. You can do it on your own if you have some technical expertise. If you don’t want to take any chances, you may contact a specialist to replace this component.

Reason #2. Blower fan motor is broken

Another cause is a faulty blower fan motor. Most people consider servicing the blower fan motor; however, this is not a practical option. We recommend that you contact the expert to replace the blower fan motor. Remember that this component might be costly (especially if you pick the high-quality alternatives).

Reason #3. Blocked vent line

Because heat and food particles must be vented out of the oven, it is constructed with a vent line.

We recommend that you inspect it for any blockages. If the vent line is obstructed, it must be cleared, and the fault code will most likely be resolved. The clog-cleaning brush is the ideal alternative. Overall, for optimal performance, you should clean the vent pipe regularly.

Reason #4. Damaged wiring

Error code F34 may be caused by broken or damaged wiring. Use the multimeter to ensure that the wires are in good working order. Next, go over the cables for any physical damage. So, whether the wires are damaged internally or externally, you must replace them.

Reason #5. Joining

If all else fails to resolve the F34 error, disconnect and reconnect the wires. Make sure the cables are securely connected when you reconnect them and the outlet is in good condition. The last alternative is to contact a professional electrician who can provide the appropriate service!

Conclusion

  1. Error code F34 on a Thermador oven typically indicates an issue with the top cooling fan air switch. Replacing the faulty air switch is often the easiest solution.
  2. A broken blower fan motor can also trigger the F34 error code. Replacing this motor will resolve the underlying issue.
  3. A clogged oven vent line can prevent proper ventilation and cooling, resulting in an error code. Cleaning the ventilation line regularly helps prevent this.
  4. Damaged or faulty wiring connecting oven components can cause error codes like F34. Inspecting wires with a multimeter and replacing any damaged wires may fix wiring issues.
  5. As a last resort, disconnecting and reconnecting wires can reset oven connections and potentially resolve error codes. 
  6. If none of the above solutions resolve the F34 error code, contacting a professional technician for service is recommended to diagnose and repair the oven properly.

F34 code points to issues with Thermador oven air circulation and cooling components. By following the troubleshooting tips for the air switch, fan motor, vent line, wiring and connections, you can usually restore the normal operation of the oven.
