High-temperature ovens are widely used in industrial and laboratory settings as essential drying equipment. However, like any mechanical system, they can encounter issues during operation. This article provides a brief guide to help you identify and address some common problems that may arise with your high-temperature oven.
If you experience the following issues, you can perform basic troubleshooting on your own:
1. **No airflow or weak airflow**: Check if the fan impeller is rotating in the wrong direction. If it is, simply swap any two of the power lines to reverse the rotation. This should restore proper airflow within the oven.
2. **Fan impeller falls off**: Open the oven door, remove the fan cover, and reattach the impeller. Make sure to tighten all screws securely before replacing the cover to prevent future issues.
3. **Air supply motor does not turn**: First, check if the power supply is out of phase. If so, immediately turn off the power and inspect the wiring. If the motor is damaged or burned out, it will need to be replaced by a qualified technician.
4. **Temperature does not rise**: Check if the heating element is broken. Open the oven’s right-side panel and replace the heating tube if necessary. Also, inspect the power connections for any blown fuses or poor contact—rewire if needed.
5. **Temperature does not drop**: This could indicate a faulty contactor, which may be burned out and unable to cut off the heating power. Replace the contactor if necessary. Additionally, check the temperature sensor and control gauge; if either is damaged, they should be replaced.
**Note:** Always ensure safety when performing repairs. If you are unsure about the issue or how to fix it, it is recommended to consult a professional or contact our support team for guidance. Attempting repairs without proper knowledge may lead to further damage or safety hazards.
