You can even order any other part you may need for making a good renovation of your oven if you find that is in good contition overall.

Hi if you oven is the Thermador CM301U you will press and hold the panel lock button for 5 seconds to turn it off. If this is not your oven can I get the correct make and model #

Hi, welcome to FixYa.

To address your post, it sounds like possibly an over-temp cut-out tripped. Here`s what and where to look for for this, (it could also be faulty double line break relay, but not as common)

Fortunately if it is tripped, they are the manual reset type and are accessible behind the black grill/vent just above the lower door next to the lock latch assembly.

**Turn off the 40amp breaker at your service panel or sub-panel in the home before attempting any service...safety first**

With the power off, you should be able to remove the grill and push the red button in the center of the thermostat and that should fix your problem...as shown here, If indeed the hi-limit is tripped you`ll know immediately because you`ll feel it click as you push it down. It will look like the image below...





Other than that if you call in a pro, I'd suggest you be sure they are an authorized B/S/H/ service provider ( B/S/H/ is the parent company for Bosch, Thermador, Gaggenau, Siemens products ).

Let me know and I`ll watch for your reply and respond as soon as I can. Good luck.

Hello,

Welcome to FixYa.

The "F34" code on your model of Thermador oven indicates the control has detected an error with the airflow for the oven.
This could indicate a faulty blower motor not coming on at all, or if it does come on ( you should be able to hear it or feel it blowing out the bottom under the door if it's working ) and still initiates an F34 error it is likely the sail switch is sticking. The switch can be removed and cleaned as they do become contaminated with dirt, grease and dust over time.

The sail switch is located at the very bottom of the ovens where the grill is, under the lower door. The blower is located at the back wall of the oven plenum as illustrated here.

( F34 can also be initiated by a failed "K4 relay" on the control board, but that is less likely )

The sail switch as I mentioned can be accessed by way of removing the lower grill...i.e. **Turn off the 40 amp breaker to the oven before attempting any service...safety first**
If you feel capable this is the procedure for testing the blower and sail switch as follows...At this point I recommend calling in a pro, it's your call.





Let me know if I can assist you further regarding this issue and I`ll try to be available asap.

Good luck.

Hi,

According to a Thermador error code book for a single Thermador oven. It says its a air flow problem. This means it could be the fan motor sensor telling the control board that it is not spinning fast or not at all. or it could be a micro paddle switch that is activated by air flow. Recap : if your fan blower motor has 4 wires going to it, it has a sensor reading the rotation of the motor.... if yours does not have this then you should look for a paddle switch.This could also be a result of fan may be too dirty to operate correctly. Try to clean the oven. If you had this error after electrical surge or outage recently, then turn off the dedicated circuit @ circuit breaker box for about 1 Hour and hopefully it would resolve the problem.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

there are two boards in the oven and i would think that it is the one on the left called the secondary . if you remove the display panel you will find the tech sheet and this should help diag the problem . thermador does use fault code's and if any have displayed / in the tech sheet you will be able to tell whats going on or in this case what isn't .. mm hope this helps .. feed back pls .

being transformer is low voltage probably shorted

F24 error code is key stuck error as the service manual of your product says (THERMADOR C302 SERVICE MANUAL Pdf Download ' ManualsLib) By replacing the faulty key or whole key board will revive the machine. As the model is discontinued/obsolete, a good service person can find alternatives to make it in working order.

If your Thermador CM302BS oven is beeping once every 30 minutes without any visible indication on the control panel, it's possible that the oven is experiencing an error or malfunction that is not being properly displayed. Here are some steps you can take to troubleshoot the issue:

1. Check the owner's manual: Consult the oven's owner's manual to see if there are any troubleshooting tips related to the beeping issue. Look for any error codes or messages that may be related to the beeping.
2. Reset the oven: Try resetting the oven by turning off the circuit breaker that powers it, waiting a few minutes, and then turning the circuit breaker back on. This can sometimes clear up temporary issues with the oven's electronics.
3. Check the oven's self-diagnostic system: The Thermador CM302BS oven has a self-diagnostic system that can be accessed by pressing a series of buttons on the control panel. Consult the owner's manual to see how to access the self-diagnostic system and check for any error codes or messages.
4. Contact a repair technician: If you are unable to resolve the issue using the above steps, it's possible that there is a more serious issue with the oven's electronics that requires the attention of a qualified repair technician. Contact Thermador customer support or a local appliance repair service to schedule a service call.

It's important to address any issues with your oven promptly to ensure that it is operating safely and efficiently.

Sounds like a shot of WD40 on the catches and pivots might help. It is kerosene based so will clean and lubricate. I looked for videos that might mention this fault, but there aren't any. https://www.google.com/search?q=Thermador+oven+control+panel+won%27t+stay+down ..

Not sure what you mean by an 'air switch', but all the parts suppliers are here including spares from Thermador themselves https://www.thermador.com/us/supportdetail/product/C302ZS/01 https://www.google.com/search?q=Thermador+c302z ..

Hi, I'm reading that you would need to turn heat and micro off and wait for the oven tempt to go down in order to clear that error. Thank you.
