Hi I am just wondering is anyone knwos how to change the temperature on a schott ceran glass hob ? It works fine apart from the fact that once it reaches the required temperature it cuts out , cools down and reheats just to keep doing the same ... I have tried having it at he lowest possible heat setting (1) and all others (up to 8) but it just keeps doing the same thing I have read it could be overheating does anyone know how to fix this ? Thanks in advance

Very specialised high tech tops need engineers to fix. It is likely to be the power board.

Question edited for clarity.
Question moved to Schott Ceran category.

Replacement knobs, but it should go by the numerical model number in the search query as well.

Schott Cerans is the maker of the glass not the model number.

SCHOTT CERAN the Original Cooktop Glass since 1971

https://www.schott.com/ceran/english/contact/index.html

The reference to Schott, is the maker of the ceramic glass itself. The label outlining the manufacturer and model number will be located on the base of the cooktop. Once you obtain that, contact the distributor to obtain the required knobs.

press and hold the power button for a min.

We have this exact same problem, and I've not managed to track down a manual (we rent and the landlord is on holiday).
I've tried holding down all buttons for a time, combinations of buttons, and turning it off at the mains, but no joy.

Did you ever solve this?

I want to say that since I posted my original problem with black spots appearing on the Schott Ceran top, I took pictures of the top and attached them to a complaint sent to Maytag. Approximately 3 days later, a Maytag representative phoned and offered a brand new top-basically stating that there is a fault with the tops. They would not pay for the labor to replace the top. My husband downloaded the instructions from Maytag website and installed it himself. These spots actually appear from within the surface and are not the result of a boil over, etc. The spots on my burner grew to the width of the burner. If you search the internet, you will see many others with the same problem with the Schott Ceran tops. I will never buy another!
