How far should the humidastate be from the main unit on an aprilaire 550 to get an acurate reading


The humidistat should be mounted in the return air duct, does not really matter how far it is from humidifier as long as it is in the return air duct.

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.

Have aprilaire #760 ,changed water panel, and turned furnace on and water started pouring out of the bottom of furnce? lots of water---


Typically, we find that the most common reason that you start to see leaking from the humidifier is that the water panel is not changed frequently enough. We do recommend that the water panel be changed once every humidifying season. We find a majority of our customers do this maintenance typically at the start of the humidifying season.

Here are the things to check when troubleshooting a power humidifier, which is leaking:

1.Position Of Unit On Plenum
Is the unit level (let to right)?
Is it plumb (front to back)?

2.Feed Tube
Is the Feed Tube tightened or is there a crack in the tube?

3.Position Of Scale control insert-
Is the base of the scale control insert sitting firmly in the drain spud at the base of the housing?
Does the bottom of the scale control insert have a taper to it to direct water to the drain spud?
Is the Scale control insert positioned correctly? The scale control insert has a front and a back. The back of the water distribution tray has an indentation in it to allow for clearance of the nozzle, which is attached to the top of the base. If reversed, and forced into place, the water distribution tray will break off the nozzle attached to the water feed tube and potentially the housing, causing water to leak

4.Water Panel Assembly-
Are there aluminum strands hanging out of the scale control insert?
Is there a gap between the top of the water panel and the water distribution tray for air to go through?
Is the colored dot on the water panel, up?
Is there a consistent coating on the Water panel, or are there shinny spots or clumps of coating?

5.Water Entrainment (Water Blowing out of the Humidifier)-
Are there signs of entrainment? Mineral build-up on fan blade, shroud, inside of cover?
Is the static pressure in the plenum over .4w.c.? If so, entrainment and leaking could occur.

6.Missing Orifice
If there is no orifice in the unit, the water entering the system could flood the panel. To check
for proper water flow, a quart jar should fill at the drain line in about 2 ½ minutes for a red or blue orifice, 5 minutes for a white or yellow orifice.

7.Drain line-
Is the drain line plugged?
Does it have a good downward slope?
Is it teed with any other drain lines?

If the above items do not resolve the existing leaking we would recommend contacting the customer service line at 800-334-6011 for further technical support.

Hello,All the pads have a protectant(white) coating because the pad is aluminum and would rot out fairly quickly from getting wet.The slime is bacteria(fungus) not from the coating that forms from stagnant (sitting) water.Make sure the unit is draining out dry after each cycle.With the pad out pour vinegar OR bleach & water (10:1) to kill the mold in the drain pipe.Do not clean the pad at all ,it gets replaced.They sell an inexpensive wet floor alarm at the store that makes noise when wet.

WHAT SETTING DO NEED MY BASEMENT IS MOLDY %SMELLY I HAVE IT SET AT 35


Hi! is it a humidifier or dehumidifier? if you want to remove mold you need a dehumidifier to absorb the moisture on the air. provided that the unit is capable of absorbing the moisture on your basement floor area. because a typical dehumidifier can only accommodate a 21 square meters floor area.
