I have a Jenn Air JJW9830DDP double oven electric, and the temperature in the oven is about 100' less than what it reads on the display. I tested the temp sensor and it ready 1073 ohms. Any s
Well, your temp sensors can still be bad. If not, there's always a new control board you buy!
However, I wouldn't drink water from that oasis without making ABSOLUTELY sure I'm not seeing a mirage.
The only common denominators between your upper and lower oven temp readings is the firmware and the oven thermometer you are using to visually check the temps.
What type of thermometer are you using to check your oven temperatures with?
If it's not a digital thermometer used specifically for testing ovens, you might just be leading leading yourself astray.
You need a calibrated thermometer. If I don't have a calibrated digital thermometer on me, I use two or three oven thermometers (the dial type) and average the readings.
It's the only way to be as close as possible with a digital probe.
If you have thoroughly verified that your oven is in fact not reading the correct temperature, then you can adjust it +/- 35 degrees F via your oven's control panel.
To adjust the oven temperature:
1 - Press Setup pad.
2 - Select the down arrow to scroll to the next screen.
3 - Select Temp Adjust using the Quickset pads.
4 - Select upper or lower oven (select models).
-"Set temperature offset using the Upper Set Knob" is displayed.
5 - Enter the desired temperature change using the Set knob.
The temperature can be increased or decreased up to 35 degrees.
The temp. change is displayed at the top of the window.
6 - Press the Set knob to accept the change.
Now, if you are still worried about the temp. reading being off, replace both the upper and lower temp sensors. That's all you can do besides replace the main board.

I have a Jenn Air
This is a control board / unit problem with these models. It is not an easy repair really, but if you are extremely handy it can be done. Let me know if you want to try the repair yourself and I can find the part.

My jenn air dual oven timer, temp lights are going out
Sounds like another control board failure, common on this type oven. It appears that a capacitor (#C3 on board) overheats and goes bad. Replacement of cap is a simple soldering job but the caps can be hard to find, try electronics parts houses and explain you need a high temp replacement. Should cost you about a buck. See post by Briangem back in may of 2008, who turned me on to the target cap. Its a 35Volt 86mF.
