Re: Mildew

If you are keeping your humidifier set to 76, this is far too high. A humidifier setting of 40 to 50 percent is about right. Depending on your window insulation, you may have to reduce the setting in very cold weather if you start getting condensation on or around the windows.
Hope this helps.

Humidity setting of the 152Z27KGM

You should have a dial setting usually on the return duct box near where your filter goes. It is probably about the size of your thermostat. Set at around 40%

Fan and tank lights won't run

I would look at the floating switch actuator. It's common for the float to bind up in the holder which keeps it in place. If the actuator is floating free, then look at the switch itself. Could be corroded or otherwise malfunctioning.

HI, Troubleshooting an Aprilaire Humidifier

Aprilaire, a manufacturer of indoor air quality products including thermostats, air cleaners and dehumidifiers, also offers a line of whole house humidifiers. Installed in your existing heating and cooling system, humidity is produced by a supplied water source that flows over a water panel before being distributed throughout your air through the heating and cooling system. Issues you may need to troubleshoot with your Aprilaire humidifier include error messages and the unit producing too little or too much humidity.

Things You'll Need:

Replacement water panel

Turn down the control dial by one setting if condensation appears on your windows or walls.

Turn up the control dial by one setting if there is a lack of humidity, often indicated by dry skin or peeling wallpaper or paint.

Turn the control dial to "Test/Reset" if the humidifier does not run. Verify the heating and air conditioning unit blower is operating. If the heating and air conditioning unit is not operating or you are unable to resolve the issue contact a heating contractor.

Contact a heating contractor if you turn the control dial to "Off" and the humidifier continues to run.

Contact your Aprilaire dealer (see Resources) if you notice an error code on the display and the "Call Dealer for Service" light flashes.

Turn the control dial to "Off" and turn off the water supply if the yellow "Change Water Panel" light flashes. Lift the front panel off of the humidifier. Slide out the water panel. Insert a new water panel. Replace the front cover. Turn the control dial to "Test/Reset" until the "Humidifier On" light flashes. If you feel uncomfortable changing the water panel, contact a heating contractor.

Tips & Warnings

Purchase replacement water panels through your Aprilaire dealer or a heating contractor.

Cleaning internal humidifier

Try using vinegar and distilled water.
If this does not work try using a little bleach and water. Repeat till mildew is gone.
Rinse thoroughly Again & Again.
Everyday humidifiers should be cleaned.
After your last uses try blow drying it. Before you put it away. If it's dry it will not mold or mildew.
Mold & mildew will cause you to get very sick.
If the mildew does not go away replace your unit.

760 aprilaire humidifier does not let water to the filter. I have cleaned and checked the lines in and out of solenoid.

Most installers wire a humidifier to operate when the furnace is calling for heat. To determine if your Aprilaire Humidifier is maintaining proper humidity, turn up the heat temperature 5 degrees above the current room temperature on your thermostat and set your humidifier control to call for humidity. The humidifier control is located on the cold air return duct. To set your humidifier control to call for humidity, turn the control dial to the off position and slowly rotate the dial until you hear a “click” on the control. You should also hear a click at the solenoid valve located on your Aprilaire unit. The humidifier control will have a click point at the current relative humidity level in your home. If the current relative humidity is 45% or the outdoor temperature is above 60F, the control will only operate the humidifier in the test mode.

  1. No click at the solenoid valve indicates an electrical problem. Contact your heating and air conditioning dealer to further check the electrical components of your Aprilaire Humidifier.

  1. The click sound at the solenoid valve indicates there is electricity to the solenoid valve. By turning the dial of your humidifier control to a setting above the “click point” you should see water coming out of the drain line within a few minutes which would indicate your humidifier is working.

  1. If the solenoid valve makes a click sound and there is no water draining from the unit, this would indicate the flow of water is being obstructed.

1. To determine if water flow is being obstructed, turn the dial of your humidifier control to the off position. The first location you would want to check for an obstruction would be at the saddle valve located on the water line supplying water to the humidifier. When checking the saddle valve, you want to make sure it is completely open. This can be done by turning the valve all the way to the left. If anything is clogged, it can be dislodged by turning the saddle valve all the way to the right and back to the left. Once this is done, turn the humidifier control dial above the click point and you should see water coming out the drain line.

If water is still not coming out of the drain, check the orifice and in-line strainer to make sure they are not clogged. The orifice is located in the tube on the discharge side of the solenoid valve and the in-line strainer is located on the inlet side of the solenoid valve. You may clear the orifice by inserting a needle through the small opening. Clean the strainer by running it under warm water to dislodge deposits or replace. After clearing and re-installing the orifice and strainer (be sure to double wrench all water connections), turn the humidifier control dial above the click point and you should see water coming out the drain line.

Hi I need help understanding the controls to my humidistat. I have a honeywell a/c unit so I'm assuming the gold colored humistat next to it is also honeywell. I bought a digital temperature and humitiy...

The higher the % of RH, (relative humidity), the more humid the house will be. I would disregard the temp part of the dial, and focus more on your comfort. Adjust it up daily until you reach a satisfactory humidity level. Hope this helps

No matter what setting is put on furnace humidifier, moisture forms on windows.House is only 6 years old and does have a lot of windows.

Hello WPwilkers, Well there's good news and good news!

First off, you should probably use the lowest possible setting as your house being so new, is likely pretty "air-tight" and as such, doesn't have a lot of air infiltration (gaps and drafts) hence the reason you're seeing moisture on the windows.

Now, I would also use a hygrometer, just like your parents likely had hanging on a wall somewhere in their house. It will give you a better idea of the moistur (humidity) around the house. My guess is that you're already at the 60%+ level of humidity.

I suggest that you turn "OFF" the furnace mounted humidifier, until you no longer see moisture on the windows. That will allow the house to adjust and get back to normal humidity levels.

Then you can start by setting the humidifier on the lowest possible setting and keep an eye on the moisture levels in your coldest room of the house, as that is where you'll first notice the excessive moisture on the windows (just the way it works - cold rooms get condensation on the cooler windows first).

If you don't have the humistat (the control for the furnance mounted humidifer) mounted next to your heating and cooling system thermostat, you should do that - it will make it easier to adjust and also will provide a more accurate reading for the humifier to operate properly.

Some Thermostats have the ability to add a humidifier on it for integrated controlling of the furnace humidifer. Check your Thermostat and Furnance owner's manual for details.

I used to have the same problem and found that by moving the humidifer control from the utility room (mine was in the basement of my house) to the living space, it made a big difference. Since most people's homes have unfinished basements and that's where the HVAC system is located, it doesn't get the same humidty readings as an occupied living space.

The other reason that you tend to get moisture (condensation) forming on windows is that the Percentage of humiditfication is set manually with the humidifier control, and yet, the outside (and inside) air temperature vary and the difference between them can cause the humidity levels to go from very dry to very moist, in a day or two.

I tend to wait until I notice that the air inside the house is getting dry and then turn on my humidifier, once the cold winter days have taken hold. In summary, nothing wrong with your unit, just mother nature and a well built (most air-tight) home are giving you higher levels of condensation than most older homes. Gradual adjustments, once you turn the humidifier off for awhile, should get you the desired results.

I hope you find this Very Helpful and best regards!

Looks like my humidistat calls for coil fan and for furnace heat

It sounds like the humidifier may be improperly wired.
It's hard to solve without checking the wiring, but it seems like the humidistat is wired so that as the dial is advanced, it incorrectly turns on the fan, or furnace, or both.  The contacts of the humidistat should be wired so that they turn on the solenoid only.  Also, the power to the humidistat, to turn on the solenoid, should come on only when the fan is on.
Hope this helps!

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.
