Hello!

Just picked up the KC Combo earlier this month and been cooking on it every weekend

First few cooks went well. Then one time I noticed smoke coming out of my pellet box during shutdown process when the fan runs high. It's done this on several other occasions since.

I've cleaned out the burn pot where the pellets drop in (the brush underneath doesn't do anything), so I've vacuumed the dust up with a shop vac. Then this can happen with as little as an hour and half cook for some burgers.

This won't happen when I'm actually cooking, only during the shutdown process. I've tried leaving my lid open and closed during shutdown, it still starts smoking through the auger to the pellet box.

I've had to resort to pulling the plug while the shutdown is still occurring, which I assume isn't good either.

I'm just using the PItBoss brand competition pellets

Any assistance or insight on what I'm doing wrong or should look at would be appreciated.

Hopefully someone will help you because your not the only one that had this problem. Can you see if the pellets are burned in your auger tube.

Personally I do not think PB fully tested there Platinum series grills.

Thanks for the response, though disappointing to hear.

Yes, the first couple of pellets that come out during the next cook are already burned/blackened.

I saw the post a few days ago about a pellet box entirely catching fire, thankfully I haven't had that happen, and this hasn't happened during an actual cook, only during shutdown. But now I'm concerned about that too and doing all day cooks or starting a brisket in the middle of the night.

Is there any hope of fixing this or do i just need to watch every shutdown and be ready to pull the plug if it happens again.

I can't return it to the store now, and I'm only on day 33 with this. :(

I am having the same issue. This is now the fourth time it has happened to me. My grill was a little over 1 month old with the pellet side completely failed. Support from PitBoss during the “Coronacation” has been less than ideal. Took five days to get a call back, and almost a month for them to ship a new controll board, fan and thermostat. Second smoke after full replacement of the three parts and I am getting smoke blow back and burnt pellets in the auger.
My control board actually has a fried diod and the fan was shot. Every time this happens I completely clean out the hopper. Burn all pellets still in the auger and shut down. Thankfully I still have ole faithful my 10 year old master forge smoker otherwise I was unable to produce brisket and pulled pork on the Fourth of July.
pitboss did not think it was funny when I emailed them Picts if ole faithful in action with a lame KC Combo in the background.

Just started seeing this as well. Fan sounds like it is blowing well, but zero smoke in the smoker, full smoke in the hopper.

I would sacrifice a few pellets if I could run the auger without the element to clear out any smoldering remnants.. but I can't even use the thermometer on the grill side without the whole system turned on.
