Kitchenaid Superba Gas Range - Oven temperature problem

The problem is: the temp seems to be 'stuck' at 260 and will not allow any higher settings.

Calling KitchenAid proved to be unuseful. The manual did not have this item in the troubleshooting pages. Resetting the power does not help.

The SOLUTION:
There is really no problem besides that the temp display setting has been somehow set to be celsius (metric system) rather than farhenheit (english system). Changing this setting somehow can be easily touched off without knowing, thus the "I didn't do anything and yesterday it was working fine..." comment from family members.

The FIX:
Reset the temp display back to farhenheit (F). This is done by opening the oven door, then hold down the 'Broil' button until you hear a beep from the control panel. The same method may be used to change from Farhenheit back to Celsius.

Prevention:
I speculate the inavertent change of the temp setting is done while cleaning the flat control panel. So the best thing to do is to always 'LOCK' the control panel when cleaning the controls. This is done by holding down the keypad "3/lock" for a few seconds until the display shows LOCK.

(The solution was already posted when I arrived at this page. I just organized it a bit by adding some details and a preventative comment. Many thanks to those who posted earlier, solving my issue as well. I hope my writing presents a clearer and quicker read to the next person)

I had the same problem. Sounds like the temperature got reset to celcius instead of farenheit.

Open oven door. Press and hold BROIL. should reset to farenheit.

Good luck! I seem to like my range. Never had any other problems and it works great.

Example of our frustrating problem: Turn the oven to 400 degrees and press start. Preheating begins and oven soon gets to 400 degrees. We put our cornish hen in the hot oven and set the timer for 30 minutes. When time is up we take the hen out and it is cold. The oven temp reads 400. We turn the oven off and immediately back on to 400 degrees and the readout says it's at 175 degrees and is preheating again. This is driving us nuts. It doesn't matter the duration: cookies, pizza, turkey, pie -- it always drops temp with no indication it's dropped. We called a service person and they replaced the control panel saying that was a common problem the new panel will fix. It worked for a few weeks after the new panel but is not back to its old tricks again. The oven is only a few years old but we're ready to drop it off a cliff

Thank you!!! I was going CRAZY trying to solve this one. I ran the self-clean last night and when I tried to use the oven tonight, it just kept giving me the ERR message. The manual from Kitchen Aide is useless. Thank you SO VERY MUCH!!!!!

PERFECT... I was on the phone with the service center and before he could figure it out I found this answer and it solved the problem.... Thank you!
