I bought a Pro 780 last October and everything was working great up to this summer. When I set my grill at 165 the lowest my grill will reach is 195. If I set my grill over 200, it has no problems keeping temp. At first I thought I was the summer months not letting my grill get that low. I recently just tried smoking some meat on a cool morning and I had the same issue. I clean my grill regularly and clean out the heating pan. I am using Cabalas brand pellets. When I first started using them I didn’t have any issues with keeping the temp at 165 if I remember correctly. Its possible it could be the pellets and I plan on buying some Traeger pellets to see if that fixes the issue. Other than the pellets any other suggestions? Help would be apricated!
