Question about Aprilaire 600 Humidifier

1 Answer

Aprilaire 110 We bought my father in law's house after he passed away. The Aprilaire humidifier (Model 110) is attached to the furnace. When the furnace came on, I didn't see any water draining out of the exit port. I went to the plumbing supply house and bought a new water panel and a new orifice and installed them. When I plugged the thing in, it was running without the furnace being on. No matter if the furnace is on or off, the humidifier keeps running. What can be the cause of this?
