Rookie collar rice cooker text message

First of all, I'm a rookie, too, okay .

Again in the circuit diagram:

The light red line of 1 indicates the line through which current flows during cooking. At this time, the temperature limiter should be closed. Among them, the fuse FU plays an over-current protection role, and when the EH is heated, the cooking indicator light also shows that it is cooking.

Deep red indicates the current loop during a thermal storm. After reaching a certain temperature, the temperature limiter works (or manually operates) to turn it off, thus bypassing L2, and the heat preservation display lamp lights up. At the same time, EH is slightly hot and insulated.

What's wrong can be pointed out.
