Harman Accentra Insert - 5 blinking lights - will not start

[fullfatboy]

Good Morning - I have an Accentra Insert which has worked flawlessly for 7 years now. I clean it regularly during the season and maintain as necessary. This year after I had the chimney cleaned the unit will not start. I try to start it using the room temperature sensor mode. The auger does not turn to place pellets into the pot. After several minutes the stove will blink 5 times. I have replaced the auger motor and the vacuum switch but neither seems to be the issue. I've been lucky in that this has been a warm Fall season but I need to get this unit up and running. Any help/ideas are appreciated.

consecutive 8 minute attempts. To reset - Turn the Mode
Selector to OFF and then back to Automatic.

Yeah, I tried that but unfortunately it did not work.
