Question about Lasko 1128 Humidifier

2 Answers

Humidifier occasionally runs in spurts (on for 2 secs and then turns off)

It does this constantly until i either turn it of or change the humidity level.

    The problem with mine is that it sputters, like it's switching on and off several times a second. I'm guessing it's on the hairy edge of wanting to turn on, but only has 1 threshold level and can't decide whether or not to actually run.

    It could be a dirty sensor or something, but I'm guess it's just a bad design.

    Had this problem on my 1128, and bought a second for the office thinking my first was just defective. Within a few months, second one did the same thing. Its a really poor design AFAICT. Hoping to find out what to take apart or clean to get both of them operating properly again. Constantly changing the humidity levels is NOT an option.

It's just trying to keep the humidity level you set it at. By dropping the temperature in your home or changing the humidity level you want you can avoid this.

Good Luck.

Check the thermo protector fuse at the bottom near the heating pad. The fuse must not be open circuit. If it is, replace it. You can order the fuse for $1 from eBay or Amazon. Good luck!

We noticed the humidity went down to 30% and I adjusted the rate to increase Now our Aprilaire 400 says to change the filter. I did that, and it still says to change the filter. The furnace runs fine....


If your humidifier is equipped with a Digital Humidifier Control with Water

Panel change indicator, after replacing the Water Panel, turn the control

knob to the "Test/Reset" position until the "Humidifier On" light blinks to

reset its timer. (Blower must be operating and HVAC calling for heat.) Be sure

to turn the control knob back to it's original setting. If the "Humidifier On"

light continues to blink, your humidifier is in Test mode. DO NOT LEAVE THE
CONTROL IN TEST MODE OR HUMIDIFIER WILL NOT OPERATE.

The humidifier says "desired humidity" when turned


I would say, either the humidity level in the room is hi or the humidifier is defective, In my house the humidity is about 42% to 45% when we use the humidifier, and can drop to 30% or less if we don't, we leave in DC area,
I hope this helps.

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.

We have an Aprilaire whole house humidifier that is functioning, but it does not have the ability to humidify our home. We have 3000 sq ft. When the heat comes on, the temperature must be high enough then...


Hi,
You can turn the blower on so that the humidifier will run more... there should be a manual on detting on your t-stat that will run the blower constantly. The humdifier should be wired to go on withthe blower.
The other option would be to install a stem humidifier which will produce more humidity faster...

Aprilaire 440 won't stop running


Disconnect the two low voltage wirings going into the solenoid valve. If the water does not stop running after a few minutes the valve is bad. When you check your local area to price a new valve. Also get a price for a new humidifier. You will be surprised to find that a whole new unit isn't that much more. Or should I say that you will find that the replacement parts are overpriced.
Good Luck

Aprilaire 700 never shuts off


Thanks for your question,
Sounds to me like you have a bad solenoid valve in your Humidifier, this will need replaced, the solenoid is supposed to open and close when there is a call for humidity only when the furnace is running, then when the proper amount of humidity is sensed by the humidistat, then will it shut off, with the solenoid not working it will let water flow through like an open faucet, the solenoid is the componet that the 1/4in copper tubing connects to at the humidifier, has two wires running from it, you will need to shut the power off before changing this out, also shut the water off at the valve at the other end of the 1/4in copper line, or you might get soaked,please be careful when installing the new solenoid, making sure the water line connection is secure, or you will have leaks, hope this was helpful, please leave a rating, thanks again for your question,

Aprilaire 600 humidity level too low


The max the aprilaire can put out is 45% Rh. Your humidifier may wired up to run only when the heat is on. In some cases this is not enough time to maintain your humidity level your seeking. To correct this, the hum. has to hooked up the hot side of the water supply. And the humidifier has to be hooked up when the fan runs and leave the fan run constantly

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.

Located My Manual:
Hope this helps!

1. Remove tank from base. Turn upside down and unscrew filling cap. Fill tank with clean, cool, distilled, or tap water. Water temp should NEVER be too hot or too cold. Return tank to base and let sit for a few minutes. Be sure the filling cap of the tank is tightened firmly.

2. Plug power cord into a 110-120V AC wall outlet only. Turn power switch to "on" position. Power light will illuminate. Turn mist nozzle until desired level is being released. Aim nozzle away from furniture and walls.

3. Always turn humidifier off when water runs* out. Unit will continue to operate when tank is empty.
*Humidifier will run up to 12 hrs on low; 6 hrs on high.

DO NOT LET WATER SIT IN TANK FOR LONG. THIS CAN ENCOURAGE BACTERIAL GROWTH.
Place unit on level surface away from direct sunlight.
DO NOT ADD MEDICATION OF ANY TYPE INTO THE NOZZLE, BASE, OR WATER TANK.
ALWAYS LEAVE ROOM DOOR PARTLY OPEN. DO NOT MOVE, TILT, OR EMPTY WHILE OPERATING.

Mild bleach and water solution for cleaning, never detergent.
Clean every 3rd day during use. Clean after long storage
Humidity varies from room to room. Aim for 30 - 50% relative humidity. If windows/ walls fog or frost, reduce mist intensity. If room too humid, ventilate by opening door or window; adjust mist intensity.
