You cannot to that degree of difference. You need to replace both oven sensors to remedy this. Part is very inexpensive, easily replaced and available at any appliance parts supply house. Looks like a small rod in the corner of the oven. If temp is still off then you can make a minor adjustment to the control.

You can change the 'offset' by doing this if you want: Select a bake temp above 500
Press Bake pad and hold it for 4 secs and release it
Press the number keys to get the temp difference you have in the display
Use the broil key to make it either add or subtract the amount you entered so the displayed temp will match your reading.
IF you mess up just repeat the process again as it can be done as many times as you want.
Maximum change allowed is 35 deg.

Thanks!

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.

Jenn-Air Gas Oven Too Hot


Hi and good morning too you. First of all the normal oven swing is about twenty degrees, so your swing of thirty up is ok. I would center the swing, bake button, should see the offset screen. Change the setting to -10 and try again to check you temps. This drift you have is ok and by changing the offset should able you to control your overheating issue and center your swing.

Good Luck, feel free to ask for more help if needed.

CANNOT FIGURE OUT HOW TO CALIBRATE THE OVEN. OVEN TEMPERATURE IS OFF 50 DEGREES. INSTALLED A NEW THERMACOUPLE. THIS DID NOT HELP THE PEOBLEM. OVEN WAS PURCHASED IN 1992. THANK YOU FOR YOUR HELP.


Without the Model Number I can only give you Basic instruction.

If your machine is Digital the best way to calibrate if find the manuel of your machine useing your Model number.

Some of the digital models : select bake and press and hold the up or down Temp button for 5 Sec to enter the calibration mode.

Some models require you do get the temp to over 400 deg befor you can enter the Calibration mode.

If your machine has a turn knob ... Take the knob off and see if there is a small screw in the center... This is the calibration screw.

I have a frigidaire stove that heats to 50 degrees hotter than the know setting. Can it be adjusted to read correctly?


There is a calibration method to adjust the oven thermostat plus/minus 35 degrees if it is a digital display. The method varies depending on the model range. This calibration method is used to adjust the thermostat if it is not keeping proper tempature. For example if you are setting the oven to 350 and the actual temp it is keeping is 325 then you could use the calibration method to adjust it plus 25 degrees to correct the temp. Just so you know electric ovens will keep a pretty even temp but gas ovens will vary by 40 or more degrees to keep an "average" temp. For example the burner will come on when the oven is 330 degrees and turn off at 370. 330+370 then divide by 2=350. So a oven thermometer may not show you the temp you set it at in a gas oven but does not mean the oven temp is off.

Hello, My Jenn Air oven overheats. When I set


The temp probe resistance should read between 1050 and 1150 ohms. If not. Replace it.It causes the overheating situation you describe.

Oven bakes unevenly and burns food


When foods are burned, soggy, or baked unevenly, it generally means heat isn't being distributed evenly throughout the oven, its escaping out the door or the controls are out of adjustment. 1) Remove any aluminum foil from racks or the bottom of the oven. 2) Check the door gasket and, if necessary, have it replaced. 3) Be sure nothing is obstructing the vent. 4) Reposition the oven racks so baking pans aren't too close to the heat sources. 5) Check your baking pans. If they're dark, they may be burning your food. Reduce temperature by 25 degrees F when baking in dark metal or glass pans. 6) Recalibrate the controls.
