Every so often I get a 5 or 6 blink status on my 2006 Harman Accentra. I have asked about this before but don't pursue it as it is the type of problem that causes "minor" inconvienience. Lately, the stove has been running good. The igniter area is clean...I can get the blinks when i run on stove or temp. mode sometimes. I wonder if I was using older pellets, or if the stove is getting "gummy" where the pellets feed. Or at times I wonder if a sensor could actually act intermittant....like the room temp bulb or the ESP in the exhaust. Can aging gaskets with door or burn pot cause draft leaking which can cause poor combustion?
