One tip with these. They rely on being housed right next to the
blower where the blower air passes over the heat sink fins.
When I replaced mine, I tried to test it, to make sure it works,
with it just hanging down, instead of mounted. I didn't realize
that where it goes, the heat sink fins wind up in the air stream.
If you test it hanging, it will work fine at high speed. If you
slow it to low speed, it gets too hot without the air and will
start to malfunction. So, it's OK to test it for 30 secs or so
like that, but don't run it much longer. Also, if you ever start
to have any issues with yours, remember that it gets hotter
when it runs at less than full speed, so if it's acting up, you
may get it to run better at full speed.
