Stampede Huge swings

[Brian0527]

I’m really new to pellet grills but I’ve done 5-6 coats oks now on my 590 and this time the temp is making drastic swings in temp. I get an alert it’s overheating 50 or more then alert that it’s cooling down seconds later then back the other way. I am just leaving it alone but wonder why it’s suddenly doing this when it held perfect the last time I cooked the same thing. Driving me crazy. Thoughts/suggestions welcome for this Egg convert.

I had swings when my 410 was new. I called RT and they determined it was likely a pellet issue. It was a new bag of bear mountain I bought.
I removed all pellets, poured in a new bag of Troeger pellets and everything was then fine.
Good starting point maybe?

Not familiar with that unit but make sure the RTD temp probe is not real dirty or touching the side.

Had the same problem. Brian Kieth at Recteq worked me through a feed adjustment. Not perfect but much better. For me the issue was holding low temps for overnight brisket cooks.

I've had the same issues with my 340. Turns out if I let a little too much residue (ash, etc) build up in the burn chamber it will start doing that. Once I vacuumed out the excess it went right back to staying right on temp. Now that I keep it clean it works well.
