I’m so sorry that has been happening, I would first recommend unplugging it and plugging it back in, if that doesn’t work, you could also try cleaning the heating element by taking off the metal skirt. Check out this post if you have any questions about that: Cleaning The Wi-Fi Version
If none of that works, then send an email to support@anovaculinary.com and we will get you all set up with a new unit as you are still under warranty!
I hope we can get you cookin’ as soon as possible!
