1. Open the side cover of the control chamber and check whether the setting value of the gas switch is correct, usually 50-80 degrees higher than the higher temperature of the machine.
2. The wind wheel of the constant temperature and humidity testing machine is not running, and the heat of the heating tube cannot be released
3. The over-temperature insulation probe is too close to the heating tube, and the distance needs to be adjusted appropriately
4. The over-temperature protector itself is damaged.
