Wasn't sure where to post this, so decided to use my grill arrival thread.
Weber rep came this morning and swapped out my auger assembly. Super nice guy. Took about an hour. He said there was something wrong with the gasket. Fired it up and it hit 500 in 11 minutes and 600 in less than 20. It is 40 and quite windy today.
I have nothing bad to say about the experience. He even let slip that a front and side shelf are coming.
I'm not sure if Lowes return window is 30 or 90 days, but either way I have a couple weeks to make a decision on whether to return it knowing about the other issues (grease fires, pellet feeding, app, etc.). I have to believe that Weber will step up and address them given the attention they are getting.
At this point, I guess I'll wait and see how the situation develops and then make a decision.
Lowes return policy is 90 days
