This is a problem with the motherboard. Just built a Jiuyang and a Rongshida health pot. The fault phenomenon is similar to this. After heating for a few seconds, the manufacturer said that the control chip was changed. Rongshida responded quickly after sale. After verifying the purchase information, the motherboard was delivered soon. Jiuyang's service is even worse, because it is a friend's, not mine, because the purchase time can't be proved without a receipt (the production date is less than 6544). It is very troublesome to repair this board by yourself, so it is better to change the motherboard directly. It is recommended that you contact after-sales service first during the warranty period (Midea's after-sales service is even worse). After the warranty period, you can buy your own motherboard, or you can buy the base for handling the broken pot body online. Midea's accessories are expensive, of average quality and relatively economical.
