No Medium Fan Speed

I have a new Vornado Whole House Ultra-sonic humidifier. I can only set the fan speed to high or to low. No medium. Is this a defect or something normal in the newer models

Oreck SL will not work on medium setting

Either your switch is not making a contact internally or the wire that runs from the motor to the switch is loose or not connected, or that speed is burned out on the motor. Those motors have a separate wire for each speed, so it's either not getting power to the motor from the switch or the that speed setting is burned out on the motor its self. I would just work around it and use the low or high setting until you can take it apart to test if the motor is getting power from the switch, if so then the motor is bad, usually the bearings go out on the motors before the wiring does. Unless your motor was on medium and was stopped for a long period and overheated that setting which will melt the wires and cause it to not work. They have a safety switch on the motors now to keep this from happening.

Ep9r 500 speed button won't work keeps flashing f

The water level sensor fell into the fan. Unplug the humidifier from the wall, stick your hand in between the fan blade and locate the sensor. It is a small black rectangular piece the size of a nickel but rectangular and 3 nickels thick. It also has a 2 inch stem sticking out of that clicks back and forth when you push it. Stick the sensor back into the sensor whole and the flashing f will go away and the humidifier will come on again.

Check all connections. Most likely, something is not firmly in place. Unplug the machine.
1) Make sure the plate is inserted into the grooves, top and bottom.
2) Make sure the contact "fingers" press firmly onto both sides of the plate.
3) Make sure the plug is inserted FIRMLY into the back (MOST COMMON PROBLEM).
4) Make sure the back screen is inserted firmly, and that the safety switch is depressed by it.
5) Make sure that the outlet is not on a line with heavy power users, like a furnace or refrigerator.

Home Depot Switch Doesn't Work. Does anyone know where to get a

Google search Hunter Fan Parts. Should find what you need, and have it in a few days.

The fan speed only works on whisper mode. Low, turbo and high do not work!

It may be faulty switch or it could be a bad fan sensor. Most likely the problem is in the switch.

Green light is on but will not operate

Hi Bran44dy,

Because this purifier is essentially a filter in a box with a fan pulling/pushing air through, I can only guess that "will not operate" means that the fan isn't moving the air.

1) Is there a fuse that you can check to see if it's blown?
2) Have you tried resetting the Filter Life Indicator button?
3) Is it still within warranty?

The instructions for this unit recommend operating it at MEDIUM level on a long-term basis - - evidently, it isn't designed for continuous high-speed operation. If it was running with a blanket over it, it's conceivable that the fan motor overheated and quit. Unless you are into repairing electric motors (probably not, the best you can do would be to replace it). Try contacting Jarden Consumer Solutions Customer Service at 1-800-546-5637 - - if they won't sell you a motor, you might be able to find a generic one on the Internet, but with a MSRP (Manufacturers Suggested Retail Price) of ~$90 (when new), it's going to be easy to spend more time & money fixing this than it's worth. There are lots more durable purifiers out there, though you'll likely have to pay for it.
