SOunds like you need to reset the oven high limit switch. It should be located behind the grille obave the oven opening and below the control panel. There should be about 4-6 screws you need to take out to remove the grille to gain access. Turn the power of to the oven at the circuit breaker, then rech in with a screwdriver and push down on the little red button in the center of the hig limit until it clicks. the high limit should be about as big around as a quarter and have a wire going into one side and out the other. If this keeps tripping, you may have a bad cooling fan. When you run a self clean it should also run a fan to cool the components. You should be able to feel a breeze coming out of the bottom of the oven when the cooling fan (not the convection fan ) is running. If this fan doesnt run, it will trip that switch. Hope this helps!

well im not terribly familer with thermadors wiring but pull the top off and find the tech sheet then look for a device call a thermal fuse or tco thermal cut off most times they are on top or on the back of the oven yours should have one for each oven bet the one for the top is open can happen if there installed in to close a space

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.

Its the thermal safety switch. When it trips - it cuts any power from reaching BOTH elements. Open the oven door - at the top wehere the oven latch is - remove the long black panel. In the middle - on the right is a small cylindrical switch...push down on the top - in the very center...it will rest the switch (like a circuit breaker) and then reassemble. Just did it on mine (2nd time) and it fired right up. Good luck
