Question about Thermador CM301U Electric Single Oven
I have a Thermador CM 301. It works fine, but after using it, when it cools down, it starts beeping. These are the same beeps that confirm the selections on the touch panel, just nobody touches the panel, and they happen ~ 2 per second. When this happens the panel is dead, does not respond any more. The solution is to switch off and on the circuit breaker, this fixes the problem.
I assume I need to replace either the touch panel, or the controller behind it, but which one? Has anybody encountered this problem?
Please see post by bonanzsapilot on 14 March 2009; he gives exact & easy to follow directions for making this repair for <$10. It's listed uner 'Thermador SC301IT oven - FixYa'. In a separate post I added the correct capacitor numbers from Newark.com. I made the fix in abt 30 min & it's good as new. Thermador no longer makes control panels for this oven & no wiring diagram is available to help. Shop price was estimated at $500.

On my C301 U, I found the brown connector on the right side of the oven control board P3-2 loose. It looked connected but while doing a shake test- Whoop, there it is. It is the sensor for the temp probe. If it's loose all the fans run all the time.

Hello, welcome to Fixya. To answer your question "Is there a cheaper fix?" In a word...maybe. **Turn off the breaker before attempting any service suggested here please** The first thing to look into is to check the harness which comes from the main relay board to the display head, they can become unsecured from the display or the main relay board/control and that will affect the display in a negative way, i.e. faded or no display illuminated. You may or may not be surprised how much those things vibrate under normal use with the cooling/convection fan running etc. and over time the harness becomes unsecured. Check "J1" on display head as well as "J1" on relay board of the display power harness and insure they are secure in place, wiggle them a bit to see if the display illuminates when turning the power back on. If that doesn`t yield any positive result`s you`ll need a new display head kit part # 492067, it comes w/harness and main relay board ( see image below ) and it is typically about $250 or so, but I haven`t had to purchase one in 4-5 yrs. I`ve checked repairclinic.com and their site says it is discontinued, but if it turns out you need one I may have one in my garage. ( I used to have my own appliance business, hence I still have some "new old stock". we can communicate via email if need be ) Let me know what you find and how it goes with the harness check, I`ll watch for your reply on your post here. I`ll cross my fingers for you it`s just a loose harness. Hopefully this was helpful to move you forward and shed some insight on what to look for at least. Good luck macmarkus :)

Apply this recommendation to solve the problem of the oven
This means that the oven has detected a condition it needs to check. Press "Cancel" to clear the display if any and to stop the beeping sound, then try turning the oven off and on again from the wall or main power supply. If you still see the "F," turn off the power to your oven again and wait five minutes before turning it on again. If you hear the beep or see the "F" when you try to bake or broil again, then it mean that it has develop a panel problem which will need some service.
Hope this help?.
Thanks for using fixya.

This error F24 and the beeping sound is unfortunately because of a bad touchpad. The error code F24 means that the key has been stuck for longer than 120 seconds. The beeping sound that you are getting means hte button is opening and closing. Heat will cause buttons to stick sometimes. When you warm your oven up it expands the buttons and makes it so a button is being held down so you can't push any more to turn it back on. The touchpad is the glass assembly on the front. You can purchase it online and that is the only part you need. Kindly click here to purchase.
Hope it helps.
Thank you for using Fixya.
