The indicator light is on, indicating that the power supply has been added to the indicator circuit. The fault lies in the electric heating tube or its connecting part. The common electric heating tube is damaged and the contact is poor. You can tell by removing the electric heating tube and measuring its resistance.
The electric heating tube is damaged and can only be replaced generally. Poor contact is mainly due to the serious corrosion or deformation of the contact reed in the power plug assembly, so the switch box can be disassembled for cleaning and maintenance.
Precautions for purchase:
1, select the manufacturer with normal quality.
The health pot produced by the manufacturer has beautiful appearance, and the upper cover and heating plate are made of imported high-quality stainless steel, which will never rust, be evenly heated and not be easily scalded. At the same time, the temperature control device is accurate and stable, ensuring that nutrients are not lost. Inferior health pots are obviously poor in workmanship and easy to rust.
2. Inspection marks
Check the appearance carefully to see if there are 3C marks and certificate marks.
