Erratic temperature on Jenn-Air elec oven

My electric Jenn-Air oven has very erratic temperatures. It has electronic controls (two knobs and a touch screen, no stove top) Sometimes the inside temperature is less than the selected temp, sometimes higher. Any ideas as to what might be wrong?
thanks.

    I have a Jenn-Air Electric Smoothtop Downdraft Slide-In Range, about 2 and a half years old. I purchased it at HOme Depot. It often loses temperature by 100 degrees or so, according to the digital thermometer on the front.

    Today, for the first time, it registered 400 degrees on a thermometer I keep in the oven, when it was set on 350.



    Shouldn't it keep a more even temperature than that???

More then likely your electronic clock control board is going bad. After turning the power off, you can also try cleaning the connectors on the clock board and make sure the connectors are tight.

SOURCE: Jenn-Air JJW8530 LCD panel does not light up

BrianGem posted a great solution back in May of '08, I just completed that fix on my own Jenn air, took me about 30 minutes once I got the correct capacitor.
The display board apparently has a weak spot in the
design, most likely heat related, (probably low priced components from offshore sources)
Fix: Replace heat damaged capacitor labeled C3 on display board, Hard part will be obtaining the 35Volt 68uF capacitor, I'm lucky enough to have a Brother in the electronics design field who found me a couple of high reliability caps designed for hot applications, He does not recommend changing sizes without design review for fear of overloading another component, however several other posts have indicated that a 35V 100mF cap has worked fine for them.

TURN OFF POWER TO OVEN PRIOR TO STARTING ANY REPAIRS.
My control panel was attached to the oven with 4 screws accessed from above the top oven door, the panel slid up about 1/2 " and lifted off, Unplug the ribbon cables and the panel can be removed to a convenient work surface. The display board itself is mounted with 4 screws and connected with a wide flat ribbon cable, the suspect capacitor is surface mounted to the reverse side of the board, two plastic clips need to be released (gently) and the ribbon cable unplugged. Capacitor is likely discolored or leaking, Using as small a soldering iron as you can find De-solder it and replace with new, match polarity marks and don’t use any more solder than needed.
If you run into trouble drop me an e-mail to dltatsjc@aol.com and I’ll try to help.
Good luck.
Thanks for this site..

SOURCE: 5 yr old Jenn Air Electric oven won't maintain oven temperature

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.

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.

Thanks
Tim

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.

The Jenn-Air Gas Range Electronic touch control 800. The key pad does not work. You can not set the clock or work the oven. Help.


My Jenn Air has the same problem with the computer touchpad. The only temperature I can get to work is from the left hand column, 411 degrees. I don't want to waste another dime on this oven. I've read so many complaints from other owners. No more Jenn Air products for me.

The ignitor is probably weak and not relighting when it needs to. Replace the ignitor.

Jenn-Air stove locked


After the lock indicator light goes out, move the door lock lever to the left. The oven door can now be opened. Turn the selector and temperature knobs from clean to off AFTER THE DOOR IS UNLOCKED. If the temperature knob is turned to off BEFORE the door is unlocked, the door will not open. Forcing the lock will damage the lock mechanism. If this should happen, return the temperature knob back to CLEAN, unlock the door, THEN turn the temperature knob off.

Jenn Aire lock for self clean in locked position


The LOCK INDICATOR light must be OFF. This can take up to one hour!!!

Do NOT force the door.

Leave the SELECTION and TEMPERATURE knob alone. The Temperature knob MUST be set to CLEAN

Indicator Light OFF, knobs set to CLEAN - OPEN the slide lever.

Lever open, set the knobs to OFF and away you go

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.
