I've got a Pitboss 820 i bought from lowes a few months back, we used it a few times with great results but after the fourth or so time, the device stopped heating. I did some research and settled on the hotrod not working. Ordered a new one and swapped it out. After which, it still did not heat up. After a few seconds i could reach in and touch the rod with no change in temp. I pulled it out through the auger tube/hopper and swapped the old back and decided to fiddle with it and turn it on. The old one started to heat up, turned it off. Swapped out with the new rod, cut it on, and almost immediately the rod heated up(faster and quicker than the original). Figuring i had a bad connection i threaded it back through the tube and set everything in place and tried cutting it on again....only to have the rod not heat back up. Does anyone have any suggestions or ideas on what may be causing this?
