7. Troubleshooting

7.1 Appliance Does Not Turn On

• While the DA 450 is designed for optimal air circulation, rotating trays halfway through the drying process can sometimes improve uniformity for certain foods.

7.3 Temperature Discrepancy

• The appliance is designed to maintain the set temperature. If you suspect a significant discrepancy, ensure the unit is not placed in an unusually cold environment or near drafts.
• If issues persist, contact customer support.
