Among its lineup of high-end refrigerators, cooktops and dishwashers, Jenn-Air -- the company that introduced convection cooking to the home kitchen -- offers a range of built-in ovens. Jenn-Air's 2014 lineup includes 19 different wall ovens, some of which feature the company's MultiMode convection cooking. These ovens vary in specific features, but some troubleshooting measures apply across the Jenn-Air built-in-oven lineup. Before you contact the manufacturer for professional service, investigate the simplest possible solutions.
Check your home's electrical service panel for a blown fuse or tripped breaker and address these issues as necessary if your Jenn-Air oven does not operate at all. Failure of the oven's LCD display and touchscreen -- common features across Jenn-Air models -- to light up may indicate a power-related issue.
Ensure that the oven's door is completely closed if the self-clean cycle does not operate.
Disable the button lock function if the oven powers on but does not respond to your control input. On the screen, beside the "Button/Screen Lock" text, slide the bar up on the screen to unlock the buttons and touch controls. On some models, you can deactivate button lock by pressing and holding "Start" for three seconds until the oven beeps twice. Likewise, press "Cancel" to disable Sabbath mode, if your oven comes equipped with this feature.
Adjust your oven's temperature offset if the cooking temperature seems too hot or too cold. First, touch "Setup Menu" on the main screen, then choose "Temperature Calibration" -- you'll have to choose which oven to calibrate if you have a double oven. Press "-1°" to reduce the temperature offset by one degree Fahrenheit or "+1°" to increase it. You can adjust the offset by up to 35 degrees in either direction. Press "Save" to finalize your choice.
Move the oven racks to a higher position if your baked goods are consistently burnt on the bottom. If your food doesn't cook evenly, ensure that at least 2 inches of space exists between your cookware and the oven compartment's interior walls. This encourages proper heat circulation.
