Do you find that your heater is running and shutting off after a short time? That might be your heater telling you it is not getting enough airflow. First and foremost, please try these cleaning instructions (https://www.youtube.com/watch?v=OwoUi_esJbY) as the first line of defense as restricted airflow is usually the culprit of this occurring. We also suggest trying the reset instructions and be sure to plug the unit into a separate outlet than the one they used previously. If this does not resolve the issue, please reach out to one of our Support Heroes by clicking in the lower right hand corner.
