Well, the tech and I replaced the WH today. At first it made no noise, after cycling a few times this afternoon, it makes a little noise when it lights but not every time and not nearly as loud as before. If/when I ever have to by another one, it will not be a GE. I am questioning my vent out the roof. I changed it a little in the WH closet today but it goes from 3″ in the closet to 4″ the rest of the way out. Maybe it is too much draw. However I just read the manual again and it says the same size should be used as the draft hood (3″) or larger but never smaller, so I should be good. GE is 1-800-432-8373. For service under the warranty, they list 800-431-1549. I am going to monitor it for a few days.
