What am I doing wrong when running Napoleon in on/off mode with t-stat?

Per manual, using stove in the "Auto" mode which is the same as ON/OFF for shoulder season.

Stove turns off when the t-sta does not call for heat in 60 minutes, this is working fine.
However, when t-stat calls for heat in one of the program modes the stove does not turn on and then it seems like 2nd red light on left just flashes.

Yesterday I was home and at 2:30 (as programmed in t-stat) i heard the unit coming on, well i think the combustion fan, but then no pellets were being fed in the burn pot and finally stove did not turn on.

When this happens and light keeps flashing i just hit the on/off button and voila, stove goes in startup cycle normally like if nothing happened.
I have only burned about 10 bags of pellets. Attached is a pic of the control board settings.

Both the door and ash pan are well secured and closed, pipe cannot be plugged or really dirty with only about 10 bags burned since bought unit new early this month..

Also, here's what the manual says about #2 flashing :

Q. My heater stopped and the #2 red light (feed light) is flashing?
A. The flashing red light indicates a vacuum switch alarm. There are several issues that may cause this alarm.
1. The main door is open.
2. The ash drawer is open.
3. The vacuum switch is defective.
4. The combustion fan is not running.
5. The vent system is plugged.

Geek,

When you put that stove in auto mode did you unplug the stove WAIT A FEW SECONDS and plug the stove back in?

Click to expand...

no, do i need to do that, the manual doesn't mention to unplug.

Also, i know this worked before b/c i remember the stove turning itself on around 5AM (the way i did program the s-stat).

..

jay, this door seals very tight because it has 2 latches and i know it is very tight the way you pull the latches.

Disconnect the OAK ??

Ok guys, i'm gonna first try smokey's suggestion of unplugging the unit, easiest option first.

I know i had moved the switch from auto to manual at some point but never unplugged unit, since i don't remember exactly and b/c i know the unit auto-started a couple times.

So i just gave it a good cleaning inside with unit unplugged. Will see what happens tomorrow early morning and see if it starts or not, if not then 2nd option of OAK will be next.

...

guys, stove started fine early this morning as programmed by tstat. Perhaps smokey's suggestion worked??

Let's see for the next startup scheduled around 2:30PM and will keep reporting back....

..

stove turned on fine at the 2:30PM cycle as expected......

Thanks guys, specially to smokey, you were right on the money with that simple solution.....

leaving office now and will stop by lowes in derby.....let's see.....maybe 2nite.

just a quick followup, hopefully the last one on this particular issue: stove started ok at 5AM today as programmed by the t-stat.

..

well, guys...........

got home yesterday and the stove did not turned on at 2:30pm, and once again the red light was flashing on #2, back to drawing board........

i will check the connections but something does not make sense here, I know i connected the 2 wires very tight to the board and should have a solid connection, but can check again.

All in all, it seemed (and i could be wrong) like if i cleaned the unit and vacuumed the firebox well then the unit will light up fine in auto mode (on/off) for a few times, maybe 3? but then i see the problem in the next cycle, this could be all speculation but will see if i can find a pattern.
