Six months ago I replaced the auger in my RT380. Since then the temperature control has been all over the map. I have no fewer than 30 emails with Support at a dozen troubleshooting calls and 20 pounds of pellets with no resolution. Prior to changing the auger I would grill at 475. The temperature may dip 5 or 10 degrees when I would flip the meat but that's it. Now, when I set for 475, the grill will heat to 483 and jump to 535, then slowly drop back down to around 475. When I flip the meat it will drop to around 400 then crawl back up. I can't find the sweet shot and things are a crap shoot. I have videos and sent same to support. Support just tells me it's weather or old pellets or not a big deal. I am about ready to trash the grill and drop another $400 since these are $100 off. I am just so disappointed in the excellent customer support and lack of what I feel to be a care or concern. So before I give up I thought I would see if anyone has encountered a similar issue.
