First time this happened and it might be the pellet I am using (first time using Pit Boss Hickory). Did a 12 hour PP run and had to refill 3x. First 2 times I added some crushed charcoal and thought that was the issue but 3rd time no charcoal and same issue. They seemed to light a little too easy. Not overfilling. Also, seemed a little weak on wood smell for hickory.
Well a few things could be going on here.
1. If you happened to have a flame up then all of the pellets would/could catch fire and burn up real quick. It happens every now and again.
2. if you refilled over existing burned down pellet cherries... well they will continue to completely burn up super quickly. I tell you this from experience :)
3. If you fill and light the
AMNPS sometimes the the 2nd row can begin to catch from the bottom. If this happens and is not rectified then you can/will end up with basically all 3 rows burning at once.
Row 1 burning because you lit it.
Row 2 burning because flame creeped under from a strong flame while lighting row 1.
Row 3 burning because if Row 2 catches and starts burning, well it burns in both directions. Up row 2 and around the bend and up row 3.
I too ran into an
AMNPS burn issue last night. It was all my fault.
The first thing I did wrong was I microwaved 100% Mesquite pellets 3 times (rather than 2) because I had some different pellets not burn all the way through on my last smoke so I went for overkill this time.
Well 100% Mesquite pellets burn hotter and better than most other pellets and don't need so much babying.
When I lit row 1, a little of row 2 seemed to catch some flame. I remove the pellets quickly but not thoroughly.
After about 3 1/2 hours I went to check and saw no smoke and looked to find all 3 rows burned out.
I believe that I fix row 2 thoroughly enough when it caught a little fire and the result turned into all 3 rows burning at once lol.
I EMPTIED the cherries and ash, refilled, and tried again (only 2 microwave cycles) and everything ran perfectly.
It happens :)
As for Pit Boss Hickory being week, I've never used it but I use the Competition Blend and like it. I can tell you that PB Hickory is probably no more than 25-30% hickory and likely all Oak, Maple, or Alder for the rest :(
Lumberjack Hickory or Perfect Pellet Hickory will be two perfect examples of good 100% Hickory pellets.
I hope this long post of info helps :)
