I have hated my Jenn-Air smooth top electric range for 6 years, especially the oven. We have had the repair man here twice. Temp was too high, cooked too hot on one side of oven, other side food was nearly raw. It would drop 100 degree just opening the door.

All at once, all these problems fixed themselves! Temp is spot on, oven cooks evenly and is back to temp immediately after opening the door.

I don't know what happened, but I hope it lasts!
