What to Check First
- Use the correct settings. Ensure that the unit is set for the correct temperature scale: °F instead of °C (Fahrenheit instead of Celsius).
- Verify START was pressed within 25 seconds. Otherwise the display will clear and the oven will not start heating.
- Preheated oven before cooking. Preheat the oven if the recipe calls for it. To preheat the oven, set the oven at the correct temperature.
- Amount of food being cooked. When cooking too much food at once, overall cook time is longer. Follow packaging directions and recipes as instructed for best results.
- Oven rack position. Cooking results can be affected if the rack is in the wrong position. The heat distribution at each rack position is different.
- It is NOT recommended to cover the racks with any materials such as aluminum foils. This will hinder even heat distribution.
- The owner's manual for each model identifies the different rack positions. Please visit our Manuals and Documents page to download a copy.
- Center pans on racks for best baking results. If baking with more than one pan, place the pans so that each one has at least 1" to 11/2" of air space around it. Do not allow pans to touch the walls of the oven.
- Using aluminum foil. NEVER cover the bottom of the oven with aluminum foil. DO NOT use foil to line the warming drawer.
- Do not block any slots, holes, or passages in the bottom of the oven or cover an entire rack with materials such as aluminum foil.
Why This Can Happen
Symptoms can have more than one cause, and the correct steps depend on the exact model, installation and operating conditions. Use the checks above to narrow the issue before service.
