I swapped mine out. I had some odd temp fluctuations around the time the started sending out the welded chutes. Ultimately I think was probably firmware related but very had zero issues since replacing it. It’s not too hard to do but I did have to remove the hopper to do it. I completely get the don’t mess with it if working fine though. One thing I remember reading at the time was people thought the two piece was allowing smoke to impact the motor but I don’t know if that was the case or not. I went with the thought of there must be something wrong with the two piece ones for them to make the change and ship them out so I went ahead and installed it hoping would prevent whatever issue the new design was for.
