The current limiting resistor of the health pot is burnt out and cannot be used. Burning out the current limiting resistor of the health pot will lead to longer cooking time and uneven heating. The temperature of water is not high enough; There is a sound of electric leakage when heating. If the resistance is found to be faulty, it should be replaced in time to avoid affecting the use effect. At the same time, attention should be paid to maintaining the health pot and cleaning it frequently to prevent long-term dry burning. If you can't replace the resistor, you can ask someone to repair or replace it.
