1. Pressure reducing valve failure: The pressure reducing valve in the rice cooker plays a role in regulating the pressure during cooking. If the pressure reducing valve is damaged or blocked, the pressure of the high-pressure rice cooker may be insufficient or too high.
2. Thermistor failure: Thermistor is the core component to control the heating circuit. If the thermistor fails, it may cause the rice cooker to fail to heat or heat unevenly.
3. Control circuit failure: The control circuit of the high-voltage rice cooker contains many electronic components, such as transistors and capacitors. If one component is damaged, the whole circuit may fail.
4. Cookware failure: Some manufacturers of high-voltage rice cookers use non-standard sizes. If the cookware is damaged and needs to be replaced, it may be difficult to find a suitable cookware.
5. Safety door failure: the high-pressure rice cooker generates high pressure when cooking, and it needs safety door to ensure the safety of users. If the safety door is damaged, the high-voltage rice cooker may not work normally.
In short, you need to pay attention to daily maintenance when using high-voltage rice cookers, and contact after-sales service in time if there is any fault.
