I had in the same fault in 2017 N17HH10NOB
The switch at the rear was ok, I tested the element in the drawer base and found it open circuit.
So I need a new draw, the element doesn't seem to be available.
If anyone knows where you can buy just the draw.
For Information, the element in the draw is a 440watt which should give a resistance of around 120 ohms

Any suggestions on sourcing the draw
