Product review (4 stars): This is my third one
In as many as 12 years with my Bryant furnace, my general humidifier uses this solenoid to control the water, I'm on the third one which has either burned out or plugged up so bad I found it easier to replace.  Much to expensive for what it does, but there aren't to many choices on the market.  I guess it's failed more than my furnace which has never had a service issue thus far.  Not a good track record for this valve.
