Well it runs for like 15 seconds then pauses for a half a second then turns back on. It does that continuously. I can get it to turn off if I set all the settings to 0 degrees on the app. But there's no in between. It's either it runs all the time or it doesn't run at all.Also, if you open it, you might have a loose wire. If so, that could short the connection and cause it to stay on. If they don't respond, I'd call in a warranty repair.
