Humidifier turns on, but is not humidifying

Can't figure this one out. The humidifer turns on, LCD powers up, the fan runs, but the water is not evaporating...even after leaving it on for a day. It's just blowing dry air. The tank and bottom tray are full of water. Any ideas?

SOURCE: Humidifier blows out dust

the manual says that you may have hard water - so minerals in your water. This may be the "dust". Try filtered or purified water.

SOURCE: How do I know my aprilair 760 humidifier is working?

A simple check you can perform on your aprilaire 760 is the following:
1) locate the two brown wires coming out of the 760 (these wires will be wired to tell the 760 to turn on when the hvac bower is on and the humidistat is calling for moisture).
2) temprarily disconnect the two brown wires from the external wiring and then short the wires together. All you're doing here is bypassing the your thermostat and bower-on indicator.

With the 70 unit plugged in to the wall outlet and the two brown wires connected together, both the fan and the solenoid valve (water inlet valve) should both be activated.

SOURCE: Testing a Aprilaire Humidifier 600 Controller

if it works in the test mode then it should be okay but you can get a humidity gauge from radio shack and set in the house to see how high or low its is. the humidifier is only going to give a max of 45% humidity

SOURCE: Kenmore Humidifier not operating?

Turn the unit off, lift the fan assembly off the base, and push the connector together that goes to the float switch on the bottom of the fan motor. If you hold the switch in with your finger (careful not to get into the fan blades) and turn the unit on, the F indication should go away. F (as in Fill), apparently, means the base has no water. The plastic tube that sticks up out of the base floats on the water and pushes the switch. Put it back together, it should work!

SOURCE: What is the saddle valve?

Your humidifier will have either a copper or plastic tubing attached to it. This tubing is the water tubing. If you follow that line to where it "taps" into a water line (near the water heater or a water line under your house), there should be a water shut-off valve. The water shut-off valve could be any type of valve but is normally a saddle valve. You could skip the step of shutting off this valve; however, it is good practice to shut the valve off for two reasons: 1. in the event of a water leak, you will be able to easily locate the valve to shut off the water. 2. if the valve is not "excercised" from time to time, the seals will dry rot and the valve will not be capable of doing it's job when the need arises.

Here is a video showing you how to trace your water line to your saddle valve. There is additional information on the video that you might find helpful as well.

When does the humidifier fan start? Does the water flow trigger it? Will the fan nt start if I turn off the water supply?

Humidifier should be powered from the furnace heating 24 volt terminals through a humidistat and then to your humidifier. The fan and the water solenoid on the unit should come on together. if the water is not turned on the fan should still run, unless the unit is not plugged in.

I installed a 700A model on my furnace (does not have a bypass but has a fan built in). It is insallted on the supply side per the instructions. The "humidifier on" light is on when the funace is running....

try tying the 2 yellow wires together that come out of it and as long as door is on properly and unit is not defective it should start if not most likely the control board inside is bad

Aprilair 760 Humidfier will not stop water flow to EV panel

If the water continues runs nonstop even when the heater is turned off, you might have either a bad solenoid valve or a bad humidistat. Simply disconnect one of the two low voltage wires going into the unit. If the water turns off then your problem is most likely your humidistat or the low voltage wiring. If the water continues to run even when the low voltage is disconnected you have a defective solenoid valve.
Good luck.......

Kenmore HW305 Humidifier putting out hot steam...Is that normal?

this is a steam and misting type humidifier, the water tanks will not heat up, the heating element is internal to the unit, just make sure you clean it periodically and I would suggest having a fan asst to help move the humidification around the room, hope that helps

Aprilaire 600: water only runs in "Emergency" Heat mode

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.

Turning on the humidifier shuts off the furnace

It is possible you may have wired it wrong. Make sure your humidifer is not robbing power from your thermostat. This would explain when your humidifer makes a demand to come on it robs power from your t-stat making it lose its call for heat. Wire your humidistat to the "w" terminal and the common terminal so it only runs on a call for heat. With the bypass type of humidifier you purchased it wont do you any good to run when the heat isn't running anyway. If you want an independent operation humidifier you need a steam type.

Continuous water draining from my General 1042 Humidifier.....

This type of humidifer is known as a flow through humidifer, when running water flows through it instead of sitting in a pan. The water draining is normal. This type of humidifer will use more water than a pan type but is much healthier due to the fact that you do not get all the build up of the pan type if you ever cleaned one. also change the water panel every year. to change the water panel there will be 2 screws on the bottom pan. Remove them and the panel will come out, buy a replacement at home depot or such store if available, otherwise from a htg company. Replacement is a little tricky to get it to line up so be patient. If you cant remove the bottom panel due to lack of room, it will come out through the top. You will have to loosen and swing the water feed tube out of the way. That is the only maintainace to this humdifier. Also with this humidifier all you have to do is turn the humidistat to off in the summer, you do not have to turn off the water as with float types.

Humidifier not collecting water

To both, these sound like de-humidifiers. Is your goal to reduce humidity and dry your room?

If so, if the humidity is low, then the de-humidifier has no work to do. A cheap battery or dial humidistat will help.

If not, check for a clogged filter. No air moving spells no de-humidification.

Also check for a frozen evaporator coil. Same as above but this requires repairs.

Electric dehumidifiers are similar to refrigerators and window AC's. With the fan running, adjust the setting to a lower humidity setting until you hear the compressor kick in. If it does not even at the lowest setting, check the space relative humidity to make sure it has work to do. If it does, repairs may be as simple as cleaning electric contacts in controls or as bad as a refrigerant leak or compressor failure. If its bad, better to replace.

A humidifier adds moisture. If you have a humidifier and want to keep the static off your clothes and keep your nose from drying out, fill the tanks with water and add biocide.

Please do not view my comments as patronizing. Even seasoned engineers have difficulty grasping humidification.
