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 suggestions what to test next? Seems to be similar in both top and bottom ovens.

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.

SOURCE: lower electric wall oven won't heat up

It is highly likely that your heating element is open so I would ( with power removed) verify the integrity of the element by detaching it and making sure it is not elecltrically OPEN, It is nothing more than a big power resistor that when current is flowing,..gets hot but if it becomes open.. you will not have any curent flow thru it ( or heat generated from it). That would be the first place I would look.. It could also be the control that feeds it..
A few ideas to check..

Rick

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: My clock and temperature display is dim

Hi, this will happen over a period of time and its just heat related. the control panel isn't insulated properly and , there has been a larger than normal transfer of heat to the inside of the control panel where the circuits are housed.

If this is a problem, i recommend replacing the control board. it will fix the dim issue.

SOURCE: Display on my Jenn-Air electric wall oven is very dim

douglas9101,
I had the same problem and found the solution on-line.
Replace the C3 capacitor on the dispaly module. (100 UF, 35 volt, high temperature)
The local Jenn Air dealer wanted $211 for a new display module.
I purchased a Cap from a local electronics supply store for 79cents.
The only problem is that you need to have a soldering pencil/iron, a solder ******/wick and a small amount of solder.

Steps I had to take on my oven:
- Flip the AC breaker supplying the oven to off to be save
- remove 3 screws on top and 4 on the bottom of the display panel
- gently pull out the display panel and unplug the 2 cables to the display
- unclip the ribbon cable to the display module
- unclip the module itself by pushing on the 2 black tabs
- locate C3
- unsolder C3 and replace with new Cap- keeping the polarity strip the same as theh old Cap
- reasemble in reverse order.

It took me all of 20 minutes. It may sound difficult but is very easy if you have the tools
Good Luck

I have double jenn-air built in ovens . when I turn top oven on it starts to beep and wont heat up.any suggestions. the bottom oven still works fine

Hello & Welcome to FixYa


This indicates an open/shorted oven temperature sensor and to solve this problem the sensor needs replacement. If you want to be sure before replacing the sensor then you can test it with a voltmeter for around 1100ohms....if it reads more than this then it needs replacement however, if the reading is around or less then 1100ohms then it is the control board that needs replacement. Please get back to me if you have any other questions.

The light and temperature display are very dim and hard to see.

We own a Jenn-Aire model W27400W oven. The display module has gradually gone dim over a period of several months prior to the end of the warranty, and the display is no longer visible. It is apparent that several Jenn-Aire oven models use the same display. Does Anyone else have the same problem, and If so, are they willing to join a class-action suit against Jenn-Aire with us?

Oven door locked - jenn air

My Jenn-Air double oven locked after a clean cycle. My model (JJW8630) has a series of slots cut in the top of the door. Take a piece of stiff wire, coat hanger, and bend a right angle about 1/2 inch at the end, feed the wire into the 3rd or 4th slot from the center on the right hand side. Turn the wire so that the bent piece is on the top and push the wire so it engages the lever which latches the door shut, it is spring loaded and moves easily.

Once the door was opened, I removed the temperature sensor, held by 2 screws, from the top of the oven and eased the wire out to get to the connector. The faulty sensor was reading 4.2 k, at room temperature it should be just over 1k, while waiting for a new sensor to arrive I stuck in a 1k resistor, ex Radio Shack, so the fan stops running and the door latch can be retracted by closing the oven door, or press the switch on the top right of the door opening.

My replacement part was ordered on line for less than 1/2 the official quoted price.

Hope this helps.

LED Display fading

As noted in solutions to other Jenn Air ovens, this is often solved by replacing the capacitor labeled C3 on the circuit board that contains the display. Oven heat apparently causes it to fail over time. This is a solder connection to the circuit board. Not hard if you have any experience with this kind of soldering it is straightforward.

Seven phillips sheet metal screws to remove panel assembly, plus two electrical connectors. One ribbon connector from touch panel to board, then four 1/4 hex sheetmetal screws to remove circuit board from touch panel and metal frame. Then soldering iron.

It did work on a 40300 dual unit, which is same as this model except for cosmetics.

Capacitor is 35 volt 68 microfarad. Radio shack has 100 microfarad, which one report says works. Radio shack doesn't have a 68, but they do have 22 and 47 which mounted in parallel give 69, which is within tolerance. That's what I used. The capacitors cost $1.29, less than 1% of the cost of a new circuit board.
