Louisiana Grill C5450 temp drop

Sounds like you may be starving it for pellets.  It may need a auger speed adjustment.  I would call their customer service, describe to them the problem and let them walk you through the adjustments to be made.

I have one of those smokers. That Louisiana doesn't have an independent feed control, so you can only set temp, Iunless yours is an older analog model - then you just set a dial).

However, louisiana's also don't relight automatically if the fire goes out. They just go out and throw an error code. Only way to trigger the "light" function is to push the start button - then it goes through the whole start up cycle.

My suggestion: first, make sure you are cleaning ash out after every use. Ash buildup can be an issue. Second, check that your pellets are good (not gone back to powder). Third, inspect that your pellets are feeding properly (push "prime" and see that pellets are feeding). If those are all good, you probably have a controller problem. Call Danson. Great service.
