SOURCE: Aprilaire 760 Humidifier water continues to run

You need to determine whether the problem is in the solenoid or in the furnace electronics. You could put a voltmeter on the solenoid connection to see if the furnace is still holding the solenoid open after the blower stops. This will tell you whether it is the solenoid or not.

SOURCE: 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.

SOURCE: The Aprilaire is leaking around the casing attached to furnace

How old is the filter? Filters should be replaced every year. If its a new filter check to make sure the little hose is inside the hole at the tom of the filter.

SOURCE: 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!

SOURCE: Humidifier won't turn on with furnace fan set to Auto.

There is a devise called a current sensing relay (a little black box that hangs on a blower motor wire that senses current from that wire) If you have such a devise it should hang from the white (common) wire. Loop the wire through twice.

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.

When furnace kicks on the air seems cold at first, is that the humidifier?


There are two sensors on the burner box of the furnace that control the fan. One tells it when the furnace has warmed up and the other tells the furnace has cooled down. If it blows before the box is hot enough, the limit switch is bad. Any heating and cooling company can get one for you and you can probably switch it out yourself.

Aprilaire 550 has exploded with water


No water should not just sit there in the system. It is supposed to recirculate itself. You should really call a tech out and have them check your system.

J-

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.
