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.

Aprilaire 700. It works on fan on mode but not otherwise. It's never on and the humidity reading is always way below the setting. It should turn on automatically to bring the humidity up, right?


It appears your Aprilaire model 700 is wired to only operate when your HVAC fan is operated by your thermostat. Your HVAC installer can wire the humidifier control to operate the humidifier during a heat call, fan call or to turn on the fan when there is a need for humidification. Please contact your HVAC installer to have them change the wiring.

Thank you for giving us the opportunity to be of service

If your humidifier is working properly, then the problem lies outside of the humidifier. For example how long does your furnance run when the thermostat calls for heat? If your furnace is oversized for your home, it will heat your home relatively quickly, and turn off, while your humidifier does not have a chance to work long enough for it to increase the humidity. If this is the case, you could try to set the thermostat to run the fan in manual mode instead of automatic. This will give the humidifier a chance to increase the humidity.

Hope this helps.

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.
