A yellow flame that high indicates that the air input is low so the mixture is too rich, so it lights very hard and it gets a poor flame.
The defect is in the burner, it's clogged by dirt. Try to clean it from the outside just by pulling every loose parts. If that fails the top of the range will have to be removed to access the entire burner, take it out from it, dismantled and cleaned thoroughly. You can find the necessary diagrams here http://www.appliancepartspros.com/partsearch/model.aspx?model_id=232125&diagram_id=193462#d193462 But i must warn you: you will be working on a gas unit; if you can't be sure you can do the job properly, without causing any leaks afterwards, you should call a repairman.
that would depend on which part you are looking for I can attest I have repaired these often and if your looking the the oven control switch I wish you great luck in finding this part due to thermador discontinueing the part after the 5 th year this unit came out although If you are unable to find the part going through thermador http://www.thermador.com/ this next link i have found actually makes discontinued parts so it may be well worth contacting them if the piece you are looking for is discontinued http://www.erepco.com/ if you have any further questions or unable to find your part useing either of these two sites message me back and I will look further into your problem and I await your reply Thanks Rick
Hi, what you are currently experiencing is a control board problem which has been shorted out due to the power outage. The board is located on the very back bottom of the unit. They've redesigned it, so it make it very difficult to follow the instructions to swap it. So you have to call in a technician to replace it. It costs about $230 to get a new board.
In other not to experience this kind of problem again, i suggest you put a power surge protector on your breaker box for the oven or else this will continue to happen. I have replace about 6 of this in the last 9 months..
One of those spark switches is probably sticking. To figure out which one you re move a ire from each one until the bad one is ID'd
Their is a harness of spark switches which individually slide over each the gas burner controls and connect to the spark module. Not sure what your model is but I have published a tip with a few repair manuals attached:
For replacing igniter( spark plugs) you neeed to order the new part for which you need the hob/oven number which might be on a sticker label on the side of the oven or inside a drawer. The model number is also required which is on the hob/oven or instruction book. Contact the spares department of your hob/oven manufacturer and buy the spare parts. Now switch off the gas and electricity to your hob/oven, and slowly note how the hob igniter ( spark plugs)comes away from the unit. Unscrew the top and it folds upwards revealing the innwards. Your igniter unit may require you to unplug the existing unit and plug in the new unit. Be sure to make a note of how the hob comes apart so that you can fix it together again.
