I think mine is a 2009ish Parlour, it came with the house. I actually do think the issue is electrical, but tied to the feed system somehow. with the slightest bit of resistance something tells it to stop "trying" to move. It should really put up for of a fight than it does, because its not really jammed, that's why I used "jammed" in quotes.
 
It sounds to me like the flighting on the feed auger is too fine, that is the spacing of the flights is too close together and/or they are rough.
 
It's actually my secondary heat, I have a Lennox Montecito 80,000 btu that heats the house pretty well. We only run it as a supplement when it's really nasty out and this week has been all below zero, or we run out of wood for the Lennox etc. And we've been running it since the start of winter thru the night, as needed etc. And I did research it and I think 40,000 btu is pretty good for this stove, and believe me it has kept us warm. We really wanted something traditional looking in our old farm house and this fit the bill. If It was my only heat, yes it would be a big inconvenience when it was down, but luckily its only down for a few minutes. I wanted a good looking unit so I weighed all the specs and it was right in there with ugliest, comparable sized units of same btu. And I researched other owners who really didn't have many issuew with theirs'. As of right now it's still running good, maybe it's fixed LOL
 
OK so I cleaned the T1 sensor, blew it out with air and vaccumed the hole I removed it from, the T2 sensor is really not cleanable, it just sits against the firebox, maybe senses surface heat, but the T2 is right inside the chimney exhaust chamber and whats interesting is its kind of a ceramic tube with a tiny sensor inside and that tube is open to the outside, kinda surprised it doesn't leak any chimney gases, but maybe the flue exhaust is constantly pulling out ? Ok so it ran abt. 5 hours never shut down, then I shut it down for the night, came down this morning, fired it up, ran abt. 10 minutes and shut down ugh ! But the interesting part is, this is the first time I was actually standing next to it when it shut down ! It was on high and the fan just stopped abrubtly and stopped feeding, like someone pulled the plug, so I immediately switched it fan to see if the fan would work, and it worked, then I immediately switched it to high and it started feeding and the fan was on like nothing ever happened, does this mean anything ??? It has now been running for abt. 3 hours non stop, I'm stumped. On another note I sent an e-mail to Thelin's "techincal assistance" e-mail. They told me they don't have technical assistance you need to contact a dealer for service ?? ugh I also ordered the brushes figured I'd swap them out for prevntative maintainence !
When it shut down had it sped up to high, or was still running at start up speed. What I mean is, this stove is setup so the fan runs very slowly for approximately 5 minutes then it will step up to low speed. It will not go higher until the T2 sensor senses a high enough temperature. If it does not sense that that temperature after another 10 minutes or so it will shut down. If you turn it off and on again it will start this sequence all over again. Thereare times when I use marginal pellets that I will have to start my stove 2 or even 3 times before it senses enough heat to step up to medium or high. With good quality pellets there is never a problem.

Ya I don't know what year mine is but it does'nt have auto ignite, which I think wasn't available till 07. so maybe mine is older ? Now you making it more clear to me, you may be right, it doesn't actually jam, but maybe it does stop feeding due to too little resistance and that shuts it down ?

I really can't tell if the fan speed changes, but I can tell you it happens within the first ten minutes, like this morning it happened after it was running for maybe 2 minutes, reset the switch its been running fine now for hours. And when I mean running, what I do is, put in a hand full of pellets, throw some gel on them, light it up, leave the door open a crack, and when they start burning nice, which is 1 -2 minutes, turn on the fan to exhaust, wait another minute and throw it on whatever setting I feel I want, which is usually medium, and then the countdown starts, could be 2 minutes, 5, up to around ten, once it runs for 10 minutes it never shuts down, just keeps running fine. I think we have it narrowed down to the auger sensing too little resistance and shutting down as Redbill said, or your scenario of it being a sensor. But we do have a common denominator here, both of you guys experienced this with a lower quality pellet, my friend has a really expensive I think Lopi insert that he says is very tempermental to pellets that have some longer ones thrown in the bag, which is what I do see in mine, this is my first pellet stove, so I don't know how consistent the length should be and if it really makes that much of a difference ?
 
Ok just an update, we decided to turn off the central fireplace for the past week and just run the Thelin. It has ran nonstop for 10 days, I cleaned it and it fired right back up and has ran flawless the past few days, no shut down, constant 73 degrees on low burning a bag a day. So if anyone has this issue, I would first try a really good cleaning, pull the T2 sensor, clean that. And try it. Second, try a different pellet, I'm beginning to think I got a bad bag of pellets with some fuky oversized pellets that caused this issue.
