2. Test the voltage of the control circuit of the circuit board, which is about 12v. If 12v is not reached, it may be that the performance of the voltage regulator is poor or the filter capacitor is invalid. If it is not normal, there will be intermittent heating failure. Also, check whether the B-pole voltage of the control relay triode is 0.7v, which proves that the control circuit is normal. Check whether the relay has 12v, and listen to the ticking of the relay. If there is no indication that the relay is damaged, just replace it. If there is no voltage of 0.7v at the B pole of triode, it is necessary to check whether the lid is properly covered or whether the inner pot is properly placed. With magnetic induction switch and temperature probe, any fault will cause no control voltage and no heating fault.

3. There are also the above-mentioned leakage, key leakage, circuit board leakage, etc., which will also cause no heat.

4. Then carefully check the circuit board for cracks or welding.

Introduction of Supor electric pressure cooker;

Supor electric pressure cooker is an upgraded product of traditional pressure cooker and rice cooker. It combines the advantages of pressure cooker and rice cooker, and adopts new technologies and structures such as elastic pressure control, dynamic sealing, external rotating cover, electric switch with adjustable displacement, fully sealed cooking, continuous pressure adjustment, etc., which completely solves the safety problem of pressure cooker and relieves the potential safety hazard that ordinary pressure cookers have plagued consumers for many years.

1, unique intelligent pressure sensing system, real-time intelligent pressure sensing from the moment the ingredients enter the pot, so that the food is always carefully crafted under the optimal cooking pressure curve, making the food delicious;

2, accurate pressure control, real-time sensing the temperature in the pot during the whole cooking process, adjusting the pressure, always maintaining the best pressure cooking requirements of different foods, releasing the best taste and retaining the most nutrients;

3. Intelligent switching of different pressures and dynamic variable pressure exhaust technology make food more delicious;

4, open the pressure window, the cooking pressure changes clearly at all times, the pressure is visible, safe and worry-free, delicious;

5. Start the 360-degree safety protection system and three pilot technologies, and then establish a new standard for safe pressure cooking;

6. Unique worry-free King Kong.
