| Ok, I pulled the manual, and you did it right.. Take the wire off of the HUM at the humidistat, and take a OHM meter and see if you have complete circuit With one probe on the first HUM, and other probe on the 2nd HUM. Turn it up to make it call for humididty. If you are not getting a reading, the you got a bad humidistat. My question is, is the transformer always hot, or cycling with the furnace? __________________ -Jay If you can do it, We can help. |
