When using the health pot for the first time, you may encounter the trouble that the lights are all on but not heated. In fact, this situation is not complicated, mainly involving several possible reasons. First of all, the indicator light indicates that the power supply is connected normally. The problem may be in the heating plate or circuit, such as the burning of the heating plate, the damage of the circuit, or the disconnection of the heating element. Secondly, check whether the switch of the health pot has heating adjustment function. If not, there may be something wrong with the switch itself. Even if the indicator light is on, the switch can't turn on the heating pipe, resulting in the heating function can't be started. In this case, it is best to send the health pot to a professional maintenance point for inspection. If it is used for a long time, it may be more economical to replace the new equipment. In a word, the key to solve the problem is to find out the specific faults and take corresponding maintenance measures.
