Product review (5 stars): Fixed our problem
We inherited a Hotpoint side-by-side refrigerator when we bought our current house. It's model number HSM25gfrfsa and definitely not something I would recommend you buy. First the icemaker died and then we found that we had to have the freezer cranked at the '9' setting for it to make any ice. Soon after that I changed the water filter and it developed a leak (this turned out to be a cracked water line). All the while the sides of the front doors were HOT and the unit was running all the time. Something was not right.

I thought that the condenser coils might be dirty so I opened up the back and took a look. Sure enough, there was considerable dust on the coil and on the coil fan as well. When I moved the fan blades to wipe them clean I noticed that it was not moving freely. When I plugged the unit back in the fan did not turn.  I thought I had found the problem.

This motor arrived quickly and was relatively easy to install. The fan now turns, the doors are no longer hot and we can turn the thermostat down from 9 and still get lots of ice. It fixed the problem.

I can't comment on the noise level as I don't think the old fan was ever working in the 11 months we lived here. But it is certainly an acceptable level of sound.
