HD 4651/C Electric Kettle Handle switch lights but...

Question

I have the same problem with a cordless HD4651 kettle where the unit stopped heating, but the handle switch still lights up. I read your post and I took the kettle handle portion apart and found a tan switch assembly near the push button in the handle. Is this the thermostat and thermal fuse assembly or is that in the base unit?
I've been having a little bit of trouble finding a parts supplier in the Mpls, MN USA area, but I'm still looking.
