How long can my 640 run non stop?
Posted: July 2nd, 2017, 11:07 am
I did my longest cook yet yesterday on the 640. I typically do 12hr ish cooks with 10-12lbs packers but the only prime packer I found this weekend was 17.25lbs. I fired my cooker up and put the brisket on at 11pm and pulled at 5pm the next day (was amazing btw). Toward the end of the 18hr cook my temps where quite unstable. In fact I had to run the cooker at 300* to get my Thermoworks Smoke to register 230*. Every cook I have ever done in two years the grate temp, door gauge and controller are within 10 degrees.
This morning I went to clean the beast and found that the firebox grate is so full I think I was close to having a hopper fire.
I burn 100% hickory pellets. BBQers Delight. Buy locally at ATBBQ. I store them properly, just like Herb suggests.
My question: How long can I really run this cooker before I need to shut off and clean the firebox? Based off this experience I'm saying 15-17hrs max?
Looking for feedback. See attached pics after my cook.
