Question moved to Thermador.

This says the adjustment is behind the control knob.

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.

Hello.

When baking or cooking common foods in your oven, it is important that the oven heats to the proper temperature. Otherwise, the food in your oven could become over- or undercooked. The electric ovens are able to be calibrated if only slightly off, however, if the temperature is 25 degrees off or more, you should replace the oven sensor. The oven sensor is the device in the oven the detects the temperature. The control board increases or decreases the oven temperature, depending on the oven sensor reading. Before calling a repair technician, attempt to calibrate your oven or change the oven sensor.

Instruction

1 Turn on the oven and set the temperature to a medium-heat setting, such as 350 degrees.

2 Allow the oven to preheat and then open the door and insert the oven thermometer.

3 Allow the oven thermometer to remain in the oven for a few minutes and the look at the temperature reading, comparing it to the oven temperature setting.

4 Recalibrate the oven if the temperature is only slightly off, or replace the oven sensor if the temperature is greatly off, such as 25 degrees or more.

Calibrating the Oven

1 Turn off the oven to prior to calibrating.
2 Press and hold the "Bake" button until the calibration settings are displayed on the display.

3 Use the arrow buttons or "+" and "-" buttons to adjust the temperature the number of degrees that the oven is out of calibration.

4 Press the "Start" button to save the calibration settings.

Replacing the Oven Sensor

1 Unplug the oven from the wall or cut the power to the oven in your breaker panel.

2 Open the oven door and remove the oven racks.

3 Locate the oven sensor, located at the top-center of the rear oven wall.

4 Remove the mounting screw securing the oven sensor to the wall and then pull the oven sensor away from the wall.

5 Remove the cable connected to the terminal on the rear of the oven sensor and then discard the oven sensor.

6 Connect the cable to the terminal on the new oven sensor and then reposition the oven sensor and secure it using the mounting screw.

7 Replace the oven racks and then restore power to the oven.

Thanks.

check that the oven thermostat probe inside the oven is not close to or touching one of the upper oven elements

It will remain locked until the temperature is safely as low as it should be. You just have to wait and be patient.

Technician just left our house with same issue. Jenn-Air had issued a technical bulletin as the temperature probe is mounted directly to the heating element, and measures the heat of the element, not the oven. Their fix is a revised temperature probe that goes at a 90 degree angle away from the heating element.

If your temperature is consistent, just off by a set amount of degrees, there is an adjustment you can make at the control panel.

Temp probe/thermometer inside oven dirty, or off attachment, or defective. On some models, a small screw head adjustment is provided to calibrate thermometer under dial knob. Else, I would just set dial 50 degrees higher rather than expense of new thermometer or dial.
