Product review (2 stars): Exact fit to my humidifier
This is the exact replacement solenoid for my furnace mounted humidifier but I dare say it looks better made than the original. It looks like this one is built to last for quite a while. And I like that fact that it was cheaper to purchase here on Amazon than it was listed on Honeywell's website. I am very pleased with the quality, and the price. And not to mention how super easy it was to install. I had the old one off, installed the new one and had it working in about 15 minutes.
EDIT: It is now April 4, 2015 and I had to shut the water supply to my humidifier off. The solenoid is not closing completely and is allowing water to run continuously 24/7 nonstop. This is a replacement to the original one and now I need to order another one, which will make the third solenoid for this humidifier. At $80-$90 a pop, I just don't want to keep having to order this stupid part if it is only going to last 1 1/2-2 seasons. And I will also add to this update that this solenoid is so noisy compared to the original one. It makes a loud clack when turning on and again when turning off. And I had to turn the water supply way down because the solenoid was allowing the full amount of water into the humidifier causing it to overflow. You would think there would be some kind of limiter built into this solenoid to cut down on the amount of water going into the humidifier but it just seems to be wide open.
