Thermador Oven won't heat after running self-cleaning cycle
Hi,
Totally frustrated here. Two years ago, after running my self-cleaning cycle, the oven would no longer heat. We thought it was the element; no dice. We called in a licensed Thermador repairman. After nearly $400, it was fixed. Then, it happened AGAIN this spring. This time they opted NOT to charge us, as they felt that they had not fixed it correctly the first time.
Guess what happened last night? After using the oven self-cleaning cycle successfully 6 weeks ago, when I used it last night, it once again killed the oven! It won't heat.
The range is only 10 yrs old. It's already been 'fixed' twice.
Any ideas/suggestions (other than mine, which was, "Oh, good, time for a new one!" which of course my husband shot down!) would be greatly appreciated.
In the meantime, I guess it's back to using my outdoor gas grill as my oven to bake Christmas cookies! YIKES!
Thanks!
Thermador Oven won't heat...broiler or bake... after running self-cleaning cycle This is the second time. The last time I ran the clean cycle the exact same thing happened. An expensive part repir fixed it . I seldom use this oven.

Re:
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!
I also had this problem about 11 years ago. A repair person came, pulled the oven out about 6 inches and inserted a pointed tool (an awl or skewer works great) and reset the oven. He then tried to charge me for this!! On my oven it just looks like a tiny hole. It works every time! And yes, my oven never works again after I clean it without doing this.
Good luck.

Hi,
If your electric oven is taking too long to heat or just not heating up right,then check out this tip that will give more detail about your problem.
Hi, Cycling the power off and then on again will sometimes reset it...often you will have to call the customer service number to get the steps to take to unlock that...
Sorry to hear you`ve had an ongoing issue like this. Can you tell me what the model number is of your oven ? Can you also maybe touch on what step`s have been taken in the past when this occur`s ?
Depending on the model and vintage of your oven, it likely has tripped the hi-limit thermostat. The good new`s is it is typically easy to reset as it is a manual reset type hi-limit as opposed to one time non-reset. Also this hi-limit is either located on side, back, or behind the grill between the oven door and control panel/fascia. Let`s hope for the later.
**Always shut off power to the unit before performing any service/repairs**
If it is indeed just a tripped hi-limit as I suspect, ( it is common after self clean cycles on many ranges/ovens, not just Thermador ) I have a few tip`s and suggestion`s after you`re up and running, but we`ll cross that bridge when we get there.
Due to the nature of the self-cleaning cycle heating the oven to above normal temperatures what likely happened is that the temperature sensor went bad. The sensor is a small rod about 6 inches long and 1/4 inches wide that sits in the back of the oven. You can remove it from the back side of the oven which will need to be pulled from the wall. Replacing it should solve the problem.
The switches on the first circcuit card mounted horizontally in the space above the microwave enclosure and behind the control pannel have burned to the point that they no longer engage properly to close the power to the oven heating elements. I do not know anyone who has removed the plastic covers and cleaned them to the point of working again properly and do not recommend trying that approach. The only sure solution is to replace the circuit card that has the three switches.
Your repairman might be right but I would have checked the main heating element first for this reason:
The self-clean cycle uses that same element as you need for the oven but is allowed to rise to a much higher temperature (~ 900-950 degrees) during the cleaning cycle and it may have self-destructed.
Since your problem started after the cleaning cycle, I would have checked the element for continuity first.
I found I have this exact problem. Same bake preheat issue: I can bake if I set broil first. However, the oven doesn't work if I press bake first. The control board has already been replaced a couple times over the years. Is this another replacement??
