Product review (5 stars): Pretty easy to install on our 632 model
Pretty easy to install on our 632 model, took a little work to get the broken one out but no big deal.  As others may have mentioned here, these switches are for the refrigerator light and **not** for the fan.  They come in a pair and I thought I was being efficient by replacing the light *and* fan switches with these new ones, but I was very wrong and it cost me some coin to find out that indeed the fan switch opens and closes opposite the light switch.  An expensive lesson to learn.
