Thermador Oven F34 Error Code – Common Causes & Solutions

Why does error code F34 appear on my Thermador oven?

Error code F34 indicates that the top cooling fan air switch on the Thermador oven is not defined. Honestly, there are many reasons for this error, but we have 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 clearly caused by the faulty air switch. However, this is fairly simple to solve since you only need to replace the air switch. You should be able to alter or replace the air switch 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. The majority of people consider having the blower fan motor serviced; however, this is not a practical option. We recommend that you contact the expert to replace the blower fan motor. Ensure you have enough money since 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 on a regular basis.

Reason #4. Damaged wiring

Error code F34 may be caused by broken or damaged wiring. As a result, you may 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 cables are inside damaged or externally damaged, you must get them replaced.

Reason #5. Joining

When nothing else seems to work to resolve the error F34, the easiest solution is to disconnect and re-plug the wires. Make sure the cords are securely connected when plugging them in. Ensure the cable is securely plugged in, the power socket is operational, and provides enough power flow. The last alternative is to contact a professional electrician, who will be able to provide you with appropriate service!
