Smoker not heating correctly

[PAS]

Maybe throw a short stack on the vent for the rear control panel models. Soup can blah blah.

I ended up setting at 250. After several hours running finally about right. Decided no foil. 5.5 hours now and they at 180. Should be long now. My 30 is dead on from the beginning but the channel type pellet smoker hard to find room for.

Which generation do you have?
Gen #1, the tray goes on the support rods in the bottom, to the left of the chip burner.
I'm not sure which one is the 140S. If that's the one with the Gen #2.5 interior, I'd put the tray on the right end of the bottom rack, just above the chip dumper. Then you can pull the dumper out a couple inches for more air flow.

Got a picture of yours (Inside & Outside)?

The temp got more correct the longer it ran. After 7 hours finally gave up on ribs. They where to tough to eat. May try to save them in my pressure cooker today. I will go back to foiling. I am about to give up on electric and just go back to my wsm. What little I ate of the ribs did not have much smoke. Used lumber jack hickory. The wsm is a great smoker and I don't know why I am messing around with electric. I do like my toys though.
