If so, it is obviously not electrified. There are about three reasons:

First, the plug-in terminal of the power cord inside the machine has come off. This situation is easy to handle. Just take the machine apart and plug the power cord back in.

Second, the cable between the main control panel and the operation panel in the machine is loose. General induction cookers use XH terminals to make this cable socket. It's possible that the button is not fastened properly and loose. Just plug it back in.

Third, the machine burned out at the end of the last use. Either the machine was flooded after the last normal use or a cockroach went in to form a short circuit. This situation is the most troublesome. If you don't know much about electronics. It can only be sent for repair. Because there are many possibilities for burned places. If you don't see the real thing, you can't judge what is wrong. However, if it is water, you can turn on the machine first. Blow the circuit board with a hair dryer. Or put it in the sun for an hour or two to see. It would be nice to do this in many cases of water inflow. If not. Then it really needs to be repaired.
