Product review (5 stars): That noise is driving me nuts!!!
Evap fan was rubbing and making all kinds of noise when running, I've never experienced this before, but found plenty of troubleshooting videos to fix this problem.  Must be a common problem with GE and it's sister brands.  These were slightly thicker than the originals (more isolation), R & R took maybe 45min to 1hr.  Now the fan is as quiet as the day we bought it.  There are cheaper ones on the internet, but with the convenience of FREE 2 day shipping this was the better deal.
