Bosch Oven Maintenance Tips
- 1Clean the oven interior regularly to prevent smoke and odor during cooking
- 2Test the door seal by closing the door on a piece of paper — replace if it slides out easily
- 3Avoid using the self-clean cycle more than 2-3 times per year to protect components
- 4Clean the temperature sensor probe gently without bending it
- 5Inspect heating elements periodically for visible damage or blistering
- 6Keep oven vents clear for proper air circulation
- 7Calibrate oven temperature if food consistently over- or under-cooks
