Induction cooktop panel not getting hot can be due to a number of reasons. Here are some of the possible reasons:

1. Power supply problem: If the induction cooktop is not connected to the power supply or the power supply is cut off, then heat will definitely not occur in the induction cooktop. Make sure that the induction cooktop's power cord is plugged into an outlet and that the power is properly turned on.

2. Damaged Induction Power Plug: If the power plug of the induction cooktop is damaged or burnt, then the induction cooktop will not work properly. Check to see if the plug is clean and free of debris or if it is damaged.

3. Induction cooktop fuse is triggered: When the induction cooktop current is too high or the voltage is too high, the induction cooktop fuse may be triggered. This will cause the induction cooktop to stop working. To rule out this situation, you need to check whether the power line voltage is stable and meets the voltage requirement of the induction cooker.

4. Faulty induction coil: If the induction coil of the induction cooktop is faulty or open-circuited, no heat will occur in the cooktop panel. In this case, it needs to be repaired or replaced by a professional.

5. Control Panel Failure: Sometimes, the control panel of the induction cooktop can fail, resulting in the induction cooktop not generating heat. In this case, the control panel needs to be replaced or repaired.

In short, if the induction cooktop panel does not get hot, you first need to check whether the power supply is normal, and then check whether the components of the induction cooktop are faulty. In many cases, it is due to power supply problems or short circuits in the wiring. If you are not sure what the problem is, it is best to find a professional to check and repair.
