I got my humidifer last year for my office. It worked just fine and I when I turned it all the way up I would be able to see the moist air blowing from it. But I plugged it into and nothing. It does not seem to be making any noise, but it is blowing "air". What should I do?

You may be havig problemm w/ the current sensing relay, try bupassing the current relay and see if the hum. comes on and if it comes on the try rapping the wite wire from the main blower 2 times. hope that helps
theholts220 - Sounds like they needed to install a bit larger transformer . You can also buy a A 50 Sensing relay that attaches to the wires for your motor and when you turn on the furnace it will allow the power to go to the humidistat. Very strange though they do not use a lot of power. Check and make sure the wires are not pinched or touching metal somewhere.
TLuzzo - The humidistat seems to be working when you turn it down. The wires for the solenoid should be hooked up to your furnace circuit board. The instruction manual will tell you where. If you dont have a spot on your circut board the A 50 sensing reley is they way to go. They are inexpensive
When your unit is on normal the outside unit works and the inside only the fan runs. your heat pump does not remove any humidity when it operates so the installation cotractor did not wire it to operate then. you can change the wiring on the humidifier to operate all the time by wiring it to the fan (g) terminal then it should work just turn it all the way to the lowest humidity when you are in cooling mode.
Depending on the age, transformers do go bad. It will have a odor to it if it is burned out, I just checked and the doorbell transformer at home depot is sufficient to run the humidifer. Dont worry that it is 20VA instead of 10VA. The VA is just the load it can handle, the higher the number, the higher the load. The transformer at home depot is around $15 dollars. You will use the 2 outer of the 3 screw terminals for the low voltage. I hope the helps. Steve
Mine had the same problem no water through the solenoid. It turned out to be the little adapter with the needle hole on it, attached to the solenoid on the intake side. It was clogged, cleaned it out and works great now.
