Jay, I appreciate your expertise input. This is just awesome!
I have skimmed through the posts and find that most have much newer furnaces than I do. Mine has Air Ease on the front cover. On the data plate inside it shows Johnson Corporation Model HAS130BD . The following link is a photo of what is in my unit.
http://www.flickr.com/photos/21141685@N07/?saved=1 I have a question:
I do not see a terminal block with HUM C W R Y1 Y/Y2 or any such connections. In fact I see no terminal block at all. It looks like just a straight 120 coming down to the switch on one side and the step down transformer for 24v on the inside where the gas valve is fed 24v and 120v is passed down to the blower fan. I am interested in picking off voltage for the humidifer to kick in when the 24v is supplied to the valve and drop out when the 24v is removed. Is there a simple way of doing this without using the sail switch? I'm getting the sense that this sail switch can be common issue. I like low maintenance worries.;)
Note: The yellow jumper wire from one 24v leg to gas valve solenoid was put in there as a quick fix due to lack of wire connector availability. I'll be taking care of that.:D
Thanks again for your input. What seems such small and easy effort for you means a tremendous amound to those of us learning!
