Pellet Stove Problem Questions – Answered by a Professional Stove Technician

I Keep Getting Clinkers in My Burn Pot. What is Causing This?

PelletStoveClinkerClinkers, which look like clumps of ash, can cause airflow issues from blockage. Clinkers are formed by burned or partially burned pellets that melt together into a clump.

There are two likely reasons for clinkers – a poor air mixture which due to a neglected or dity unit, or incorrect air adjustments.

My Pellet Stove Won’t Ignite.

There are a variety of reasons for your pellet stove failing to light.  The most common reasons – bad air flow, a dirty unit, bad igniter, blown fuse, bad gasket around igniter – could be easily avoided with regular maintenance and professional inspections.

The Heat Isn’t As Hot As It Should Be.

Not feeling the heat you were expecting can be frustrating. The most likely culprits for this issue are – a dirty unit blocking proper airflow, a neglected/dirty heat exchanger, and incorrect blower settings. If none of these are the cause, and you purchased your fuel from Woodpellets.com, give our Quality Control Manager a call to walk you through what’s happening.

Pellet Stove Service and InspectionsMy Stove Keeps Shutting Down

Many newer units will flash a light on the unit, and will give a reason on the screen for the shut down. You may have noticed the common causes for most pellet stove problems by now – a dirty unit, and poor air adjustment which won’t provide enough heat to trip the sensors. Also, your pellets might not being feeding into the auger correctly, due to a worn down or broken part.

My Flame is Very Lazy

If your flame is weak, or “lazy”, you’re not getting the heat you need and your stove might shut down. This problem is most likely caused by a bad or weak blower exhaust, poor air adjustments, or an uncleaned/neglected pellet stove.

    I have a ravelli pellet stove, it gives me an error of… smoke sensor… we cleaned the stove and replaced the sensor, but still will not stay lit, and gives the same error. How can I fix it?

    I have a ” US Stove 5660 48,000-BTUs 200-CFM 2,200-Sq.Ft. Large Automatic Bay Front Pellet Stove” and the air flow is not working right. It is not burning the pellets the way it should. We clean it eveyday & we take care of it really well. How would we go about fixing this?

  • Joe ewing

    Can the flue connect to hot water flue

  • Christina

    This is my first pellet stove. I’m getting a lot of partially burned pellets in my firepot and it’s overflowing. The trim is confusing to me. My handbook says if it’s lazy flame, or sooty turn it down. If it goes out or doesn’t ignite properly turn it up. Which is more air? What should I did to prevent overflow and waste?

  • Jackie pavlicek

    King peeled stove model 5500M Why when i turn on pellet stove it runs to the normal run and then shuts off and will not turn on unles you unplug and plug back in??

  • Kevon James Fansler

    I have a magnum 3500 when I start it the auger runs. After about 5-10 minutes all the fans are still running however the auger will shut off. If I turn the unit off (without unplugging it) then dial it back on the auger motor kicks back on.

    • Michele Collins

      Try making sure the little peice where lid shuts that senses the lid is shut is up enough for enough pressure for lid to push it down. My husband bent it up just slightly for this reason

  • Brian harding

    Mytimberwolf pellet stove will not feed. I jumped the vaccum swith and it works. Replaced the vacuum switch . But still does not work. Looking where to turn next

    • Fraser Davis

      check to see if you have a “fines box” Same thing happened to me. When jumping the vacuum switch it ran. Replaced the switch, still nothing. Emptied the fines box and started right up.

      • Brian harding

        What is the fines box

  • Michele Collins

    My King pellet stove model kp130 will start up slowly also putting way too many pellets in. But then go to shut down saying Er-11. We just got the thing few weeks ago and ran fine.

    • rosaelefant

      Have you resolved this?

      • Michele Collins

        Yes problem was a clogged pipe due to us burning a lot of paper from wood stove we had. Cleaned that out and never had a problem since. Also I suggest getting a little metal shop vac made for vaccuming ash. We always have to make sure to vacuum it out before each use and also opening those ash trap doors on side of burner area and vacuuming about every 3 or 4 uses as these do get clogged with ash. Also you have to use a good hard wood pellet. You may have to try a few to find the right ones but you’ll know when you do because you will rarely have any unburned or on the sides. One thing we did on our settings is turned the “pellet loading” time down. This helps with the pellet overload and keeps it running smoothly. To do this hold top buttons- heat rate and Aug until a number shows. We set ours on 1.75 as recommend, since it’s set way to high from factory then hit start. It’s been running pretty good since we’ve done all this, so far so good- just got it in late September. It’s a lot less work than wood. Only thing we have to do is bring in a bag of pellets, dump in hopper, clean out ash. I do have to check hopper every so often as all pellets near end of being empty will stay up on the sides and I push them to the middle. We keep ours on HR 1 and, RF auto and DF 1. We use about a bag (40 lbs) a day if it’s running all day. With a modular home 2,144 sq ft. We have a ceiling fan above stove on low and a stand up fan on other side of room to circulate the heat. Also, we don’t have a clean air pipe as it’s not required for this model so we keep air circulating. We also have the standard pellet pipe going up and connecting to our wood stove pipe (believe it’s 6 in) and where a 90° is the pellet stove “T” pipe with removable bottom for ash dumping.

  • Jessica

    Have a ravelli rv100 it ignites but the room blower never turns on , it’s only three years old . Can’t seem to figure out why it’s not working

  • Elzie

    Igniter light is flashing even though the pellet stove is fired up than the fire will go out

    • rosaelefant

      Replace the igniter or clean the stove.

  • Keith

    I have an error code 5 on a King Pellet stove KP130 which says blown auger output fuse. Where is the fuse located at

    • rosaelefant

      Probably near the external termostat. Just open it up and clean it at the same time. Your user manual is probably downloadable on the web.

  • Ken Gallagher

    I have a King Pellet stove KP130 and it take to long to ignite are it will not lite at all

  • rosaelefant

    Hi. I have an Extraflame baby fiamma from approx. 2006. When i start it up the fans start spinning like they’re in cooldown mode. The display is blinking in an non-rythmical way like theres not enough power. I’ve cleaned it. Checked the fuze and restarted it. If i remember correctly there was a couple of powerouts in the neighbourhood before the issues. Anybody?

  • Samantha

    I have a king pettet stove 5502m & its showing ercode 3.. I’m guessing its to do with the auger.. how would I go about trying to see if the auger is like jammed? I’m a young female & pretty much a newb when it comes to the pellet stove so please be as simple as possible but please help!!

    • Michele Collins

      Try making sure the sensor switch it clicking when lid shuts and make sure it’s sensing the lid is closed completely. My husband had to bend that peice up slightly the make it read the lid is shut for enough pressure to be on the peice. Read my reply to my question (it’s a long response) we have a King pellet stove. This explains everything we’ve done to make sure it runs smoothly.

  • Milan Mihailovic

    It’s runs ok on level 4 and 5 but if I reduce to 1,2 or 3 after five mins it will turn off showing and error NO PELL even though the hopper is full, but the burn pot if full with inburned pellets.
    It’s hovered t within an inch of its life bit still the same problem.
    If anyone can help it would be appreciated.

    • Ollie

      Did you ever solve that problem? Same thing with my extraflame

      • Kevin Coloe

        Hi Ollie.
        I actually fixed it myself last week . The guy I purchased the stove from had the auger set for hardwood pellets.
        When I checked ,my auger speed was on -45 . I increased the feed to -25 and it’s perfect now . If your not sure on how to adjust the auger let me know …

        • Ollie

          Thanks Kevin. I’ll have a look at it tomorrow and let you know if I’m in bother. Thanks

          • Kevin Coloe

            To get into auger settings press and hold 3 then press 5. Then keep pressing 5 until you see F . You will see you feed setting in display window 1..
            2 will increase and 3 will decrease. The finish by pressing 1.
            Hope this sorts it for you.

  • Tim

    Question my king pellet stove over heats if I go above heat 2 and it’s doing this because the room fan will only wrk 1-2-3 and when I put on numbers 4-9 it does not go any faster. But it revs up ea time 1-2-3 but no more at all when I go 4-9 on room blower fan. I see nothing in manual that shows I can reset or replace say a snap disc. There are none?

  • Jason hawkes

    Hi there. I have a san ring sr r11 model 674b. It lights ok and runs ok but when the burner plate turns to empty the ash ect, when it turns to go back the the correct position it stops in the wrong place so the next lot of pellets drop straight through to the tray

  • LISA RACANIELLO

    When turned on pellet stove blowing cold air and ignitor light not coming on.

  • Kenneth Colaizzi

    Replaced the convection blower, When operating on low blower does not operate smoothly. In other words slows down and then speeds up. On occasion will almost completely stop.

  • Kevin

    I have a 2006 glow boy. Replaced the Combustion fan last year and the control board this year. Every once and a while the Combustion fan will just stop running or turn very very slow. If i shut down and restart its fine or if i adjust the trim down it will start running normal. What the heck is going on here? Sometimes it can be 2 weeks before this happens or 2 days.

  • Joe Dorety

    I have a Timberwolf TPI35 that I put a new (not OEM) igniter in. I then started blowing the ignitor fuse. Running the stove manually (hand lighting) the stove works fine. Put in another new ignitor (non-OEM) and the same thing is happening. Do I need to increase fuse size or go back to the OEM igniter?

  • Ryan loeper

  • Ron D

    I have an Amesti 8100 (Italy) pellet stove. Have a sporadic problem. Every so often, maybe 5 days or so, it will not ignite. I just restart it and it works fine. I clean it every day, including the glass. Could it be the pellets? Buy from the same place I always do.
