If you encounter a "temperature error or temperature out of control" during the use of an electric thermal constant temperature blast drying oven, here are some self-checking steps and solutions to help you troubleshoot:
1. The fan is not operating properly or has not been turned on;
Solution: Check the blower and replace it if necessary. A faulty fan can prevent proper air circulation, leading to uneven heating.
2. The difference between ambient temperature and the set temperature is too small;
Solution: Ensure that the set temperature is at least 10 degrees higher than the ambient temperature. This helps the oven maintain stable internal conditions.
3. The indicator light is dim or the temperature rises unexpectedly;
Solution: This could be due to a thyristor breakdown. Replace the thyristor with one of the same type to restore normal operation.
4. The Pb.PK adjustment is not working correctly;
Solution: Re-adjust the Pb.PK settings according to the manufacturer's instructions. Incorrect settings can lead to inaccurate temperature control.
5. The PT100 sensor has poor contact or is damaged;
Solution: Inspect the PT100 probe for any signs of damage or loose connections. If issues persist, replace the PT100 with a new one to ensure accurate temperature readings.
Regular maintenance and proper usage are essential to keep your electrothermal constant temperature blast drying oven running efficiently. Always refer to the user manual for detailed guidance and safety precautions.
