    So, I fired up the pellet furnace today, and the feeder auger won't cycle? What is my issue? It comes on and will not shut off, so after about 10 minutes pellets start falling into ash bin.
    Any suggestions?

    You can try doing a board "reset" by removing power from the furnace for 10 minutes.If that does not work,I would suspect a exhaust probe or control board problem,probably the board.

    X2 on the Circuit Board and this time make sure the furnace is on a very good surge protector. I only recommend the Tripp Lite brand simply because they work!

    Question is, was the power disconnected since last heating season? As mentioned above, power surge/spike fried the board?

    Ya, the furnace worked before. The light cycles off and on, but the auger keeps running. the furnace was connected, and no to the surge protector.

    Lot of garbage on those "clean " grid lines. A separate Earth ground ( not tied to the neutral line) now days is a must. If you have an older place a lot of times they are tied together in the fuse/breaker panel.

    My house ground was tied to the old heavily oxidized copper water pipe going into the street. When my electrician upgraded the 100 amp panel to the new 200 amp panel he put in a ground stake and tied the new ground wire to that. :)

    Are you getting a blinking light on the STATUS light? If so, how many blinks? You may need to run it for some time (maybe >35 mins ) to get that code. Is it igniting itself? Are you using the included wall thermostat? What are your control board settings?
    Possibly (in order of likelihood):
    1. ESP probe
    2. control board
    3. igniter (?)

    The status light was solid, did not blink. I did a manual light as the igniter is not working great. Yes I am using a wall mount thermostate. What should my control settings be? I just use the standard settings.
    Thanks

    clean the igniter, its should work fine then...…..are you using the HARMAN thermostat?
    Feeder = 4
    Temp = room, 75?
    igniter on

    you really need it to run for a bit...…possibly the ESp (cheaper than the board)

    then I would make sure the igniter is operational......after a lighting cycle, or, preferably two lighting cycles, your burnpot above the igniter will be either hot, or cold. If its cold, probably a bad igniter. If its warm or hot, its likely dirty.

    Hey. So I did some work and got the igniter running. The fire light and away it went. But it's not working right, the auger is still running even after it reached temperature. I have thermoter beside thermoset to show temp. Also there is no power at thermostate or where the thermoset hooks onto furnace. And the igniter is still running, even after running the furnace for 5 hours., and lots of heat and 80 degrees. Lol. The wife is happy, it's like 80 degrees in house and still running why I trouble shoot. Is there a switch or something not allowing thermostate to work? Or should I try a new probe or do u think it's the board? I also switched from auto light to manual light and still sending power to igniter. Thanks

    1. After like 45 mins of operation , are you getting a blinking STATUS light? If so, how many blinx?
    2. Does the igniter light ever go OFF?
    3. Does the auger run continuously, or on and off?

    No, the status light stays solid.
    The igniter light never goes off, and I checked it with pin tester and shows still sending power.
    The auger will not shut off, even after thermostate set at 70, and room temp got to 80.

    Triac in the board is likely fried. Usually this happens when someone shorts out the igniter (some point in the past?). Check board settings, and have a DDM put on the unit to see what the ESP is reading for temperature. Should be giving you a 6 or 5 blink error.

    the only way to test if the igniter itself is truly on is to have the stove running well, and put a hook, or loop meter on one of the igniter leads and see if there is current

    I to have a PF100 and am having a odd one also.
    Mine was going into a 2 blink , I cleaned the furnace immaculately ! Cleaned ext pipe & chimney, even went as far as pulling the Auger And checking for residue . Furnace was totall gone thru 2 years ago. New door , burn pot , all new gaskets etc.
    Worked all last winter and this far this year.
    I’m not sure what made me do it but I cycled The limit switch on the blower and the blink went off.
    Anyone ever seen this ? Possibly Bad switch or ?

    Possibly - Neutral (White) runs through that switch to the junction box -> the combustion blower (according to the PF100 schematic), a voltage check may reveal a loose or degraded connection. *Disclaimer: don't own a PF100, just checked the electrical schematic. Would also check any (Door, Frame) switches, if applicable.
