    I finally fired it up and all was going good. First off I ran a test and all the lights came on and went through it cycle with no problem. I then put it on stove temperature and four feed and five for temperature. It fed pellets and the combustion motor was fine, ultimately after 5-10 minutes the feeder goes off and never comes back on. Also the distribution blower never comes . It only comes on when I shut off the pellet stove. I also tried want to get on room temperature mode because I have the wires for that it did the same exact thing do you guys think it’s the board. I did notice when the pellet stove is on I would see the feed light come on for second and then go off. Any clue

    Has the ESP been cleaned?Possibly dirty or defective.

    yep pretty clean, but why would it work OK on manual setting but not on auto ignition.

    Yep that is strange.Kind of reverse of what it's supposed to.


    The Accentra Pellet Stove is capable of manual operation. This also allows the operator
    to manually control operation during an emergency (i.e. igniter failure, when using a
    502H battery backup, or when using certain generators.)
    The unit can be switched between "AUTO" and "MANUAL" at any time during operation.
    Ignitor Switch to "MANUAL"
    Room Temperature Mode
    The fire will have to be lit with starting gel and a
    match, or started automatically, see "Automatic Operation".
    Turn to "Manual" position when the fire is established.
    The difference between "AUTO" Room Temperature
    Mode and "Manual" Room Temperature Mode is
    that the fire will not go out as the room temperature goes
    above the control board setting. The unit can only go to
    low burn and will remain there until it runs out of fuel or
    until more heat is needed and the feed rate increases.
    Feed rate adjustments and dial settings are the same
    as "AUTO" settings.
    Ignitor Switch to "MANUAL"
    Stove Temperature Mode
    The advantage of this mode is to allow the operator
    to have a large viewing fire without blowing extra heat
    into the room.
    During operation, with the temperature dial set at
    #5 or less, the distribution fan will not operate. A #5 on
    the temperature dial and a #5 on the feed adjuster is
    approximately 80% output. It is not necessary to operate
    the distribution blower below this point. Therefore,
    there can be a higher feed rate ( a larger viewing fire)
    without an excess of hot air blowing into the room.
    An example of when to use the Manual Stove Temperature
    Mode is if you want to watch a large fire and
    the room is aleady up to temperature. The Stove Temperature
    Mode allows you to have a larger fire and a
    lower sound level, without the distribution blower.
    NOTE: During the use of this mode, if you keep
    increasing the temperature dial setting to increase
    the fire size, the distribution blower will automatically
    come on when the ESP Temperature reaches
    350o F, or 81% output.

    Another thing to note is after it fires up at start up and done feeding the pellets, I observed the feeder light go on and off ever 12 seconds.

    Last thing to figure out is every time I open the door to clean the ashes from the burn pot while it’s running the feed stops and it shuts down. Any suggestions

    well, the feed should always stop when the door is opened..
    stove detects a vacuum leak and pauses or stops...
    as far as shutting down, not supposed to... got me there....

    it's reporting a vacuum leak but it's not letting go..
    sounds like your board may be flakey..
    hope someone chimes in with better idea but don't know what else would cause the shutdown.
    should just pause the feeder till "all clear". so to speak. not shut it down for good.
    is your hopper lid tightly fastened/?

    Sometimes vacuum switches act goofy,after warming up.Might be cheaper to replace it first.
