Product review (5 stars): Noisy fan?  BEWARE - try fixing it yourself first
I haven't installed this item but I know it's a good price since I shopped around and I like Amazon's return policies.  My message is this: if you have the "noisy cooling fan" problem like I did - try to fix it yourself first.  I took the fan out to make sure I was ordering the correct part, I ordered it, and then noticed the fan itself had edged past the end of the fan shaft.  Over 14 years the plastic fan had worked its way down to the end of the shaft that spins it,  and it was hitting the fan grill which was making the noise. I pushed the fan back up the fan shaft to what I guessed was the original position, re-installed it, tested it, and found out the problem was fixed.  If it happens again, I will apply some super glue to hold it in place on the shaft.  But I don't expect to hear anything for another 14 years.
A day earlier my local appliance guy told me he had heard of this noisy fan problem before and it was definitely a bad fan and would cost around $120 for the fan and a minimum of $130 for the labor.  That's why the five stars for this price.  Also the local parts guys would not have taken this part back since it is "electrical".  So you really want to make sure it is broken before you order the part - and when you do order it, make sure your seller will take a return if it turns out to be something else.
