Question about Comfort Zone Heating & Cooling
Unless you want a new house, stop using that heater immediately. There are severe internal electric problems with your heater. Since it's already 3 years old, I'm not sure it's worth trying to repair. With what you described, I'm surprised it didn't trip one of you circuit breakers.
Be safe, Don't continue to try to use this heater.

The AO4 is a board used by Earthwise on the Comfort Zone Heater. The reading is the board being used. If the heater just gives that reading it may need to be reset. This can be done by pressing up, down and enter at the same time. If this does not work unplug and try it again. Hope this helps
