My air King Air humidifier number 9929 is not getting power/turning on. No green light or LCD display. Would that have anything to do with a bad filter

I had this problem several years ago. In order for the water to flow, the outside temperature sending unit must indicate to the controller that it is less than 60F. If not, the unit will not operate outside of test mode. Check the temp outside where your sending unit is (could the sun be heating that side of the house?) and ensure that the circuit to the sending unit is working. I had a bad wire splice inside a wire nut stopping the circuit. Took me a long while to figure it out.

If the outside temp and your sending unit circuit is ok, I wish you luck on your troubleshooting.

This is an old post, but you can make sure the humidity adjustment is full high. Perhaps it is defective or possibly, the environment is as humid as the high setting will allow.

I would suggest turning up the humidistat (usually located on the the return air duct to a higher setting and listening for a "click" noise on the supply valve. If you do hear a click but dont see / hear any water than the culprit is likely the valve itself.

the lubracation used in the fan motor has an expected life of 5 years... once the lub is gone from the oillite bearings then the fan will stop .. you can put a couple of drops of oil on the motor bearings if you can get to them .. spin it by hand a few times to distribute the oil ... dont use WD40 or Teflon filled Oil .. use a light non gumming machine oil .. since you cant get that oil to permiate the porous bearings (done in a vacuum) then you will have to relube every year or so to keep it going .. you could replace the motor but that might not save much over a new unit .

SOURCE: how to clean air-o-swiss humidifier?

Gererally according to the booklet in the box.
If you no longer have those instructions, simply clean out the
basin, make sure no mold, dust, hardwater or calcium is deposited.
Use a 10% bleach water solution to kill bacteria, and thats is basically it.
Just dont miss any spots, but humdifiers should be cleaned every few uses.
