Troubleshooting Guide: Fixing Burnt Crackers on a Direct Gas Fired Oven with Ribbon Burners

Burnt crackers don’t just impact product quality—they can also slow down production and increase waste. If you’re experiencing this issue with a direct gas fired oven equipped with ribbon burners, the good news is that many causes can be addressed through regular checks and adjustments.

Here’s a step-by-step guide to help you get back to consistent, golden-baked crackers:

1. Verify Temperature Settings

Double-check that your oven is set to the recommended baking temperature. Even a slight increase above the target can cause crackers to scorch quickly.

2. Inspect Ribbon Burners

Examine burners for buildup, blockages, or damage. Clean them regularly to maintain even heat distribution and avoid hot spots that lead to burning.

3. Confirm Gas Supply

Ensure the gas supply is steady and adequate. Low or fluctuating pressure often results in uneven heating that can char crackers in certain zones.

4. Calibrate Burner Settings

If your burners allow adjustment, make sure they’re properly calibrated. Incorrect airflow or gas settings can throw off heat balance and create burn risks.

5. Check for Hotspots Inside the Oven

Look for signs of uneven heating—such as darker patches on trays. Misaligned burners or poor ventilation could be the culprit.

6. Track Baking Time

Crackers bake quickly, so precise timing is critical. Even an extra minute can tip them from crisp to burnt.

7. Use Baking Sheets or Trays

Placing trays between the product and the direct flame helps buffer heat and prevent bottom burning.

8. Rotate Baking Trays

If your process allows, rotate trays halfway through baking. This helps distribute heat evenly across all crackers.

9. Inspect Oven Insulation

Worn or damaged insulation can cause inconsistent oven temperatures. Ensure the insulation is intact and functioning properly.

10. Refer to the Manufacturer’s Manual

Each oven model has unique features. Reviewing the manual often reveals maintenance and troubleshooting tips tailored to your equipment.

11. Schedule a Professional Inspection

If burnt crackers remain a persistent issue after these checks, it may be time to call in a qualified technician. They can perform a deeper assessment and correct hidden problems.

By following these best practices, you’ll reduce waste, improve efficiency, and keep your crackers baked to perfection—crispy, not burnt.

Burnt crackers don’t just hurt product quality — they waste time, energy, and resources.
