Hi Nancy. There is a fuse or fuse like device in the bottom of your teakettle. There is also a temperature control switch which may be faulty. (if faulty, it is 'open' and the pot thinks the water is hot already) If you have a volt/ohm meter, you can probably find and replace it. You will need the replacement part and tools to install it, including pliers, screw driver and a crimp tool.

since it is three months old, you should consider contacting the manufacturer for relief on this matter.

Good luck on your repair and thanks for visiting FixYa.com today.
