Hey all, finally got an inherited Quadra Fire up and running and dialed in. It works great when I have only a small amount of pellets in the hopper.

If I fill it up even a little, it stops feeding pellets. Can the hopper being full really be the issue?? I’m using Lignetics brand pellets. I did buy a bag of Heat’rs to see if they make any difference, but haven’t run out the ones in it yet. Anyone see this issue
 
Auger motor may be weak, not enough power to turn with the weight of all the pellets in the hopper.

No, it’s definitely turning. I’ve had the side panel off and can see it working. It will sometimes be fine for a couple hours after loading up, sometimes it does it right away. It got stuck yesterday and it was barely 1/4 full. I looked at the pellets and there doesn’t appear to be any excessively long ones or anything.

The feed opening is adjusted more towards the narrow side, but if I open it anymore, it dumps too many pellets and the fire gets out of hand.

Like Sysko said, feed motor is kacking out. Replace it.

Is there a set screw were the motor and spring assembly attach if it is loose it could turn when few pellets dragging on it and slip when a lot of pellets?

From manual: Page 16
16. FEED SYSTEM
The feed system pulls pellets up the feed tube from the hopper,
using a hollow auger spring, and drops them down the feed
chute into the firepot. The feed rate is adjustable; for complete
instructions read the fuel feed system in the cleaning and
maintenance section of this manual. NOTE: The feed motor
will not operate when the front door of the insert is open. If
you are having fuel problems, check the following:
A. Check the ramp in the firepot to see that it is free of fuel or
other materials.
B. Check the set screw on the end of the motor shaft to see that
it is tight and not slipping.

C. Check the electrical power to the motor.
D. Check the vacuum switch hose connections.

Not the best picture it is a snapshot off a vhs tape but inside that black hole is a set screw.

Take a small mirror and a lightvand look up the feed tube and see if there are pellets bridged or something blocking the down tubw

I keep wondering why they use an open helix instead of a conventional solid center helix (auger) like everyone else uses. I'd think a solid center helix (auger) would feed better and be less prone to jamming plus it would require less power to elevate the fuel.

Think if I had one (Quad), I'd refit a solid center auger from another manufacturer myself.

Just don't like the design and it requires you to purchase a part that is unique to the unit too so, they can charge more (for less in my view).
 
Hey https://www.hearth.com/talk/members/rockymtnguy.73024/, or any others who might have ideas, were you ever able to resolve this issue with the pellets not feeding even when there is a full hopper? I have an 1100i and during the day I tend to check the hopper and help move the pellets down, if they are "stuck" on the front wall. Sadly, overnight when I'm sleeping, the pellets at the bottom of the hopper will feed properly, but those at the top act like a log jam and do not fall to the bottom. This makes the stove think that the hopper is empty, so it shuts down, and I wake up to a house that is only 61 degrees! I don't like that! I go to check the hopper and it actually appears full, but with just a slight movement of my hand on the pellet dam, they fall down to the bottom where the auger can feed them and the hopper is then only about half full. But I have to push the reset button because the stove has given up on trying. The auger and everything else work fine. I think the issue is that the front wall of the hopper is too horizontally sloped at the top, and not vertical enough. Because of this, the pellets tend to just pack in place and not move without some help. I know the stove says the hopper holds a 40 lb bag of pellets, but maybe I shouldn't put that many that maybe become too compact. I am considering letting all of the pellets feed through and burn so the hopper is empty. Then considering using something slick like RainX on that hopper front wall to see if it helps. If that doesn't do the trick, my next thought is to measure the inside of the hopper and make a secondary front wall out of metal or something else that is rigid. I would have it end several inches above the auger opening, then prop this secondary wall to be more vertical so that the pellets will be more likely to fall down to the bottom. I realize this would result in losing capacity in the hopper, but at least it would keep my fire going over the cold nights! I made this video to share with my brother because I'm always asking him questions about how to deal with stuff. It gives an idea of what I have described here. Thank you, in advance, for any suggestions you might offer!

This topic has been discussed many times (pellets not sliding down hopper walls .
Try removing all the pellets. Clean the hopper walls ( lite sanding if needed) use a
good paste wax on the walls It should help. This worked on my stove many years
ago and have not had a problem since

Thank you for your quick response and referral to the other thread! I had only searched for this problem with my stove model. With cold weather, time is of the essence to resolve this problem! I'm going to let the hopper empty itself overnight and try cleaning the walls tomorrow along with some type of wax product on the front wall (the sides and back are vertical, so this problem is only with the sloped front wall). I will make sure to allow whatever I do to thoroughly dry and not drip down into the base of the hopper. I will report back to update the thread if this works, or if I have to resort to something else. I hope this works because it would be much easier! Thanks again!

Hi Johneh, thank you for the welcome to the forum and I really appreciate your quick reply because I'm tired of waking up cold in the mornings! I had only searched for issues with my stove model so had not seen other threads. I am going to just let the stove run overnight, until the hopper is empty, so I can try this solution tomorrow. The back and side walls of my stove are vertical, so it is just the sloped front wall where the pellets are bridging or compacting. I hope I am as lucky as you and it works! I bought my stove off Marketplace in early 2023, and hired an installer to put it into my existing fireplace box. Heating with pellets saves me so much on my heating bill and my furnace has rarely run since I got the pellet stove. I have read and watched everything I can get my hands on to learn about maintaining this stove. Someone shared the tech manual above and I saved that! After having to replace the igniter a few times, and they are so fragile and expensive, this fall I decided to try one of the newer type stainless steel igniters. My brother helped me to ensure I got one that met the electrical requirements. I installed it about a month ago and it is working great! These are so much more durable and much less expensive! Here's a link to the one I got: https://a.co/d/efOum7L
Thanks again and I will update the thread if this solution works for me or if I have to try something else!
 
Hey fellas (at least mostly!), I tried cleaning the hopper front wall and waxed it. Filled it with pellets and still have the bridging problem. I have tried several things since and didn't want to update until I found something that works well to share with y'all. First I just placed a vintage enamelware medical tray inside with the bottom up. They are very slick and it was about 3/4" deep. I just leaned it against the front wall when the hopper was empty. Then I filled the hopper and it actually worked pretty well by making the front wall a little more vertical. But I kept thinking about the issue. I have had this pellet insert since early 2023 and have not had this issue with pellets hanging during previous seasons. So I believe it is actually an issue with the pellets left from last year. I bought a new ton this year, however, I realized I had about 26 bags left from last season because I got a steal ($.55 per 40 lb bag at Tractor Supply!) on them mid-winter when I was afraid I might run out. Anyway, they have been stored where they stay dry, but they still could have been subject to humidity (I live in far NE Texas). I store them in 4' cube laminated plywood shipping containers. They keep critters from chewing holes in the bags. I will share that I am a 64 year old widow and I unloaded a half ton of pellets in 30 minutes into the first container! The hardest part was trying to heave them across the 4' wide box to try to keep the level even all the way across. I wanted to move the other container to sit beside the first one and that's when I realized I still had 26 bags left. Those containers are very heavy empty (each is the equivalent of 2.5 sheets of 1" plywood, coated with laminate, with straps, and a pallet attached to the bottom) so there was no way I could move it with all those pellets inside. That meant leaning over the 4' high side to remove all the bags I could reach, then climbing in to get the ones from the bottom. Got the container moved and unloaded the other half ton from my truck. I had also purchased 10 extra bags and moved 4 of them. I was too worn out for any more that day. I moved the other 4, plus 8 of last year's pellets into the 2nd container. The other 18 bags of last year's pellets were moved into my rarely used den because I wanted to use the old ones first but didn't want them left outside and I was out of room in my containers. So, basically, I moved 2+ tons of pellets by myself in 2 days. All that to say, I think the old pellets could be why I'm experiencing issues with the bridging this year. I will try burning one of the new bags, and hope it burns well like they have in the past. But I still have to use the old ones, so had to find a solution. I wondered if I used some kind of a weight placed on the sloped front of the hopper above the pellets, maybe the weight would help to push them downward as the auger moved ones from the bottom. It needed to be heavy, sorta small, yet big enough that it wouldn't slide all the way to the bottom and get in the way of the auger. I searched the house and found a motorcycle battery I bought for my generator. It was still in the box, so I just placed it above the pellets, where it would slide. And it worked! I need to send that battery to my brother who is working on my generator though, so I had to find something else. I remembered my hand weights, so I made a very sturdy box for one of them out of the heavy duty cardboard corners used in shipping fragile stuff. The box is taped up well so it slides, and the 8 lb hand weight fits into it perfectly. I placed it on the front hopper wall and it pushes those pellets all the way down to the bottom. I check from time to time and move the pellets along the sides of this box so they are below it in the hopper. It works great and I don't have to worry about it. The inside of my hopper doesn't even get warm when a fire is going, so I felt it was safe. Definitely safer than a motorcycle battery! But that was just for short term anyway. This will work as long as it needs to. And I still hope that it really is just a "last year's pellets" problem. If not, I will use this solution until I figure out something even better! Thanks guys, for your help! I read every thread on this site that had anything to do with the 1100i, or any of the other issues I have had to tackle! I am pretty proud of how much I have learned! I will be selling this home in a year or 2 and building a barndo on my parents' property in central Oklahoma. I will check back with you guys as I start planning my new home. I will definitely heat with a pellet stove but will know better what to look for in my next one! Will be ready for your recommendations at that time! Thanks and stay warm!
Oh, the pictures! First shows how it slid down to the bottom, pushing the pellets, but stopping above the auger!
Second shows how I fill the hopper and place this at the top so it slides and pushes the pellets down.
Third is just the box with the hand weight. The box could be deeper, but it works fine. It is very sturdy.

Thank you, ARC! I feel pretty sure that my issue is with using last year's pellets that may have degraded some due to humidity. They definitely seem to have more dust than when I used them last winter. I intend to try a couple of the new bags of pellets purchased this year to see if they slide better, the way they always have in previous years of use. If so, I will continue to use up the rest of last year's using my sliding weight to force feed them to the auger. If I continue to experience issues with the newly purchased pellets, then I will definitely be trying other options, as you suggested! I have another idea up my sleeve to try, as well, just out of curiosity since there are others with the same issue that have not found a resolution. I will report in after testing my new prototype! Thank you!
