Hello, everyone. Hope everyone had great holidays in the past few days.
Here is an update on my Harman Accentra 2 problem. To recap, I posted a few weeks ago with a problem of a 6 blink shut-down on my Accentra. I got the stove used a few months ago and it was installed in my house by a professional Harman-trained installer. It is in the corner and has a 90 degree elbow, 3 feet up, 90 degree elbow, 3 feet out through the wall for venting. It uses outside air for combustion intake via a special Harman thimble that combines the intake and vent pipes into one thimble. The vent pipe is 4". The stove kept shutting down with 6 blink error code when the demand for heat was low, but would crank for days on end during high demand periods. So far I have done the following at the suggestions of people in this forum.
1. Thoroughly cleaned the stove several times
2. Replaced the exhaust temperature sensor (ESP)
3. Tried adjusting low draft speed from one extreme to the other
4. Pulled the auger and re-sealed its bearing assembly to the feeder weldment
5. Emptied the hopper and re-sealed the seams in the hopper and the interface between the hopper and the feeder weldment
6. Made sure the intake back draft flapper isn't sticking
7. Always make sure there is no pellet bridge (that would not make for a consistent problem anyway, but still...)
After all that the stove still shuts down with a 6 blink error code when the demand is low. By that I mean the outside temperature getting into say, high 40's and the room temperature on the stove set at 65 degrees. This has happened int he last couple of days. Now that it's well below freezing again, the stove is cranking.
So, I am still at square one and am still looking for suggestions.
Thanks!
