SM025 Won't Hold Temperature

Decided to try some tests rather than just shut it down.

Set at 225°, climbs to 257/259°, which is really 270° according to my ThermoPen®, I have seen other posts that theirs goes to the high limit and shuts off.  270° is too high for ribs in my opinion, may have to opt for the Pit Barrel tomorrow.

Will keep monitoring it for a while to be sure.

Check out Auber PID controllers if you don't want to stay stock.

Thanks I'll do that, I saw an earlier post that mentioned inkbird I kind of glanced at their website but I've been pretty busy today.

I like the look of the stock controller but I'm not hard pressed to actually keep it, it fits in my built-in set up but I'm sure I could probably put almost anything in that enclosure.

Make sure your internal box probe is clean and free of debris.

You do know don't you that the 025's are hard wired to run at max for about 20 minutes at startup to get the smoke going.  Maybe that's what you are seeing.  Just my $.02

After the rise on initial heating, does it ever come back to set? If not, I suspect the smoker box probe. Either some coating or build-up preventing it from accurately reporting temp to the controller, or a bad probe, which should be easy to replace. I'd try that before replacing the entire controller, which may not correct the bad probe reading, and leave you with the same problem..
