My Comfort Zone Infrared heater by Earthwise is showing two different faults on the display, ao5 and doFL, what do they mean?

Make sure the unit is clean. Especially, the blower wheel. If that doesn't resolve your error code then follow these instructions.

Look that over please, you can clean the blower wheel at the red arrow, jumper the two switches at the blue arrows as *brief tests only* just to see if the unit runs and begins to heat with the jumpers in place.
If it runs, replace the item that failed open.
If it does not run, the control module, Item 5 marked with green is most likely bad and needs to be replaced.

turn on heater ao5 comes on hit temp switch clicks but goes back and forth from ao5 to temp degree is it the printed circuit board please email at [email protected]

One of the heat tubes has failed.. need to replace the bad tube.

Everytime I turn on the CZ heater, the display reads A05 and then it goes away when i set the temp. As far as I can see and feel, I'm not experiencing any issues with the heating, fan, or thermostat or the extension cord running hot. I'm concerned that something could be wrong or unsafe, with Comfort Zone filing for Chapter 7, anyone know who is offering support or a number I can contact?

Hi. I have the Comfort zone 1500 (cz 1500) and just ran into this AO5 problem. Turns out the thermostat was set lower than the actual room temperature. I just turned up the heater temp and it kicked right on. Hope this helps!

According to the call line, hold down the up, down and enter buttons all at the same time and it should clear it. I took mine back and had it replaced so I never had a chance to try this.

Hello all , just push and hold the two buttons on the right for 3 seconds and it will reset. Joe

I have the exact same problem. How did you get it fixed ?
