Just stopped working. Tested switch,all contacts have power, capacitor is good. Need a wiring diagram so I can open motor and see what's wrong. Had very little use in ten years.


Can't help you, but I've read they have as high as a 20% burn out rate. Most report failure if they operate with the window screen on (creates too much airflow restriction) and most failures are with the capacitor. Other than that, you need to contact the company and try to get it replaced under warranty.
If you need to replace the motor, you can call the parts department at 800-233-0268 (M-F 8 to 4 EST.)

Aprilaire humidifier 110


Hello, typically solenoid valves should be replaced every 7 years and they are not very difficult to replace. Just need to shut off water at saddle valve, turn off power to humidifier, and remove mounting hardware. Here is a link to store which sells the solenoid needed for your humidifier. http://www.aprilairehumidifierparts.com/product.php?p=aprilaire_4005&product=111011&category=1686

Our Aprilaire is over 14 years old. Two


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.

Is it worth fixing my aprilaire 112 which is 17 years old or replace it with a model 700


I would advise you to replace your old humidifier. The reason for this, is that at 17 years old, you will probably find that parts are scarce, and fixing one thing only breaks another. Also, the old humidifiers, by design, are a perfect breeding place for mold and algae, and switching to a new flow through type is advisable.

Coleman kersene furnace in mbile home, (furnace is only 4 years old--just inspected 3 months ago) However,it ran fine last night, now it will not come on unless you hit the ret switch, then it tuns 20-30...


Sounds like a fuel or ignition problem. If the unit does ignite when its reset it could be a bad Cad eye or primary control. If it does not light off when reset,DO NOT re-rest anymore and call the Heating contractor back to inspect and repair.

Water only runs with humidistat in test/reset mode. Aprilaire 600 with an Aprilaire 56 Automatic Humidistat, both about 5 years old. Water line is clear, and test mode runs fine for the 1 minute interval....


you need to make sure your humidity level in the house isnt higher then what your humidifier will provide at any givin outdoor temp. this chart is in the owners manual. you cant remove the wires going to the ODS or it will give an error unless you have a resistor to put in its place. Anyway if the humidifier works in test mode according to AA it works so you may have higher humidity than you think, the highest your gonna get is 45% as the temp outside drops it will allow less humidity so it doesnt cause window condinsation (property damage) here is a copy of the chart. the #s on the left are the dial setting

NEED MOTOR, EATON 416 025 20 FOR SEARS FURNACE HUMIDIFIER


It`s pretty expensive but Appliance Factory Parts has the same motor except at 24 volt and you have to use the gear from your old unit and a step down transformer..as yours is 115 volt..

Around $80 as they will combine the shipping if you call them..

Local electric motor shop repaired my 1994 motor for $35 after I explained to them I could not find a replacement..

I talked to Sears repair service man, he said our units are too expensive to produce today but are better than these new high flow models they use allot of water that just goes down your drain..

Turn off the saddle valve going to the humidifier. Remove the water lines going into the solenoid valve. Clean the filter screen and the orifice in the water lines right next to the solenoid valve.

First of all the white build up is hard water residue. If you haven't replaced the filter in 3 and a half years you NEED to replace it. They have a safety switch may not be satisfied because of your filter.

Fan is running but humidity is not changing


Q: My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the tank decreasing.
A:
First, check the filter to ensure it is wet. If the pad appears dry, remove it from the Base and gently rinse under cool water. Reposition wet filter in the Base. You may also want to note the current moisture level in your home. If the humidity level is over 60% the unit will not put out much moisture
as your air is already saturated.

UV bulb and filter are user replacement items

OK?
Comment by Soulvisitor, posted on Jan 20, 2008 Q: I hear the fan turning, but I don’t see any mist. Is my humidifier operating properly?
A:
Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no
“mist” emitted. When operating normally you will feel only cool air coming from the unit. Monitor the
water level in your Tank/ Base. If you notice a decrease in the Water Tank over 24 hours then the unit
is operating normally.
