Great replacement

MRβ€”January 29, 2025

The humidistat that was installed when my humidifier was installed went bad so I replaced it with this. It was very easy to install myself which saved me a bundle that I’d have had to shell out to a furnace repairman. Works just as good as the original. Price was very reasonable. Read more

Replacement for my Aprilaire humidifier which happened to be the same one a Serviceman was going to charge me much more than what I got from Amazon and it was the same exact one. Read more

Still have the problem

Raggβ€”January 12, 2025

After a few years of use the valve that's controlled by the humidistat started to chatter. Cleaning the unit and check the wiring didn't help so I finally decided to replace the humidistat. It didn't help. I then replaced the valve and it helped some, but I can still hear a muffled chatter. What's up with that? Be aware: if you have "chatter" replacing your humidistat may not be the answer. Read more
