Product review (5 stars): Timely delivery and works fine
The part arrived quickly and in working condition.  Fixed a problem with my heat pump where the indoor blower would occasionally stop blowing while the system was cooling, resulting in an iced up unit.  (Note that other things can cause this condition too; it required some logic tracing and a multimeter to diagnose... my old relay switch was receiving a signal to run the fan, but the fan was not receiving power from it, so replacing the switch seemed like the thing to do.)
