Hello, welcome to FixYa.
I'll start by saying, I just received an email saying you were asking me a direct question...I will tell you what I know based on my experience with Thermador (extensive) and the description of your post. This sounds like a possible hi-limit thermostat tripped scenario.
I don't know if you know where it is or how to check it, or if this is the case with both upper & lower ovens...but they are independent of each other on the SC302T, so if you can reply and elaborate I'll b glad to help in any manner I can. Thank you for choosing FixYa.

Hello again,
I just wanted to follow up on my previous post now that I'm at my primary PC and have more access to my data-bank/files.
In looking for an over-temp cut-out tripped. Here`s what and where to look for for this,
Fortunately if it is tripped, they are the manual reset type and are accessible behind the black grill/vent just above the lower door ( just below control panel for the top, and just below upper door for bottom oven) 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 ).
Hope that answers your question and gets you back up and operating, if not keep me posted and I'll provide assistance in any manner I can as stated previously. Good luck.
Regards,
Macmarkus :)
Dear Macmarkus,
I have been looking for a couple days for an article that more specifically showed me where the breaker switch was located and you have provided the perfect fit. Thank you so much from Dexter, MI. !!
Hi Bill,
just wanted to say thanks for commenting on my service tip for the Thermador oven. I will soon have more info available on my blog site,

...thanks again.

Hi This means a
loose/broken wire on the oven temp sensor or the oven temp. sensor itself is
bad and should be replaced. To solve this issue test the oven temp. sensor, it
should read between 1080-1120 ohms, if the rating is more then that and the
door appears to be closing fine then it is the control board that is bad and
should be replaced. Hope this helps...please post back for further assistance.

Hello, welcome to FixYa.
I've read your previous post's and can see a couple of scenarios have been thrown out there, so this may just add fuel to the fire...no pun intended.
It sounds to me like a tripped hi-limit safety thermostat is the culprit, hence neither ignitor so much as glows. I'll explain. If the valve where faulty the ignitors woul;d still glow as it is the ignitors which allow the valves to open not the other way around.
Further to that, if the ignitor where faulty, it is unlikely it would be both at the same time, however if a hi-limit safety tripped it shuts down power to both the broil and bake ignitors thus no oven function at all...that is it's function "safety".
The hi-limit safety on your range is on the back wall so you need to slide the oven out (if you haven't done so by now) to inspect it. To do so is pretty easy, one of two ways.
You can jump across it to see if it allows the oven to operate or you can ohm it out with a meter. it should simply be a closed circuit if good, open if not. It is the non-reset type unfortunately so you'll need to replace it.
example
It is part number 8300802 and available at "repairclinic.com" or "searspartsdirect.com" to name just a couple.
Let me know what you find and I'll be glad to help you moving forward from there. Good luck.

Likely to be the Hi Limit Switch or the relay/power board.

Hi.
Problem is usually either temperature probe or heating element.
Grab a multimeter and set it on impedance (Ohms).
Remove first temperature probe and then heating element.
If either probe or element is reading open (ohms infinity), then replace the part.
If both probe and elements are not open, then the problem is either wiring or oven electronic control. The most common fault resulting in no heat is the temperature sensor located inside the oven cavity.
Regards.
