What to do if my Utilitech NTH15-18ARD stops, flashes, and the buttons don't work?

If your Utilitech Heater suddenly stops, the display flashes, and the buttons don't respond, it likely overheated. To resolve this, unplug the heater and allow it to cool down for at least 10 minutes before using it again.
