1. Power supply: Many health pots use electricity to boil water. If the power supply is unstable or the power cord is poorly contacted, it will cause the health pot to light up for a while. You can check whether the power supply is normal or try to change the plug of the power outlet.

2. Internal structural problems of the curing pot: short-term current may be activated or turned off when the curing pot is heated, which may be related to the temperature sensor, heater or control circuit inside the curing pot. If these parts are damaged or not working properly, it will cause the incubator to light up and dim for a while.

3. Heat preservation function: Health pots generally have heat preservation function. Some health pots may automatically adjust the heating power according to the temperature, and it will light up for a while and work normally.

In either case, if there is a problem that the health pot is turned on and off for a while, it is recommended to contact the after-sales service center or professional maintenance personnel for repair or replacement.
