jenn-air ww27110 model electric oven -- no error codes but upper oven will not operate in any manner, bake, broil or clean. You can select bake and put in 350 degrees and unit stays there a few seconds and then the temp indicates 100 degrees but nothing is happening. I assume the electric control is the problem? Is it? Lower oven is on manual controls and it works just fine. Cannot find anyone who still supplies the control P/N 71002123.
