Motor runs but wheels don't turn

I love this humidifier but at some point the wheels stopped turning, therefore no humidity. Can you help? Rosemary

    The answer makes no sense to me. I can take the cover off and open it all up but that doesn't answer the question of why the wheels don't move. What should I be looking for.

The manual available on this page is very helpful: http://www.venta-airwasher.com/html/technical_data.html

Here's what is says about the disc stack not turning:

Problem: Disk stack not turning
Check that the rubber coupling is properly inserted into the bottom of the gear.

It also indicates that there is a 10 year limited warranty, if your unit is younger than 10 years you should probably call Venta at 1-888-333-8218 to inquire about service.

    There is also some very detailed instuctions on removing and replacing the gear and bushing and on cleaning it thoroughly which is probably what you need done to get your machine running again.



    Here is what the manual has to say (without the pictures):



    Servicing your Venta-Airwasher

    Cleaning the gear

    Do not submerse the gear in water. To clean any buildup of calcium or lime from the

    gear “teeth”, brush with a soft bristled brush. The gear teeth should be pointed

    toward the floor while brushing, otherwise deposits will fall into the gear and cause it

    to malfunction.

    Removal of gear and coupling

    1
    Switch the unit off (to ZERO position).

    2
    Unplug the power cord from the A/C outlet.

    3
    Remove the motor housing from the upper housing.

    4
    Remove the coupling from the gear by pushing the coupling down toward the fan and

    away from the gear.

    5
    Pivot (turn) the gear 90 degrees so it is laying on its side.

    6
    Gently pull one of the two motor housing arms approximately 1/8 of an inch away from

    the gear and remove the gear from the motor housing.

    7
    Remove the locking ring from the center shaft of the fan by prying it up using a small

    screwdriver.

    14

    4 5

    6 7

    Replacement of gear and coupling

    1
    Place the rubber coupling into the locking ring so the rubber feet from the coupling

    hang below the ring. When placing the coupling and ring on the center shaft of the

    fan the rubber feet should line up with the notch marks on the fan.

    2
    Snap the ring and coupling into place.

    3
    With the gear laying on its side place it between the motor housing arms that

    suspend it above the fan.

    4
    While placing the palms of your hands against the motor housing arms, apply slight

    pressure, and pivot the gear to the operating (upright) position. Check that the

    locking knob (flange) is properly seated.
    The locking knob, on either side of the

    gear, should fit tightly behind the ridge of the motor housing suspension arm.

    5
    Insert the rubber coupling into the bottom of the gear and push it up into the gear

    until it fits tight. On models with a small white pin, first insert the pin through the

    rubber coupling and then push both up into the gear until it fits tight. Check that

    this is properly seated by spinning the fan with your hand. The teeth in the gear

    should slowly move in and out.

Ok Rosemary...some of the information here is helpful.

What makes the wheels turn(unlinke Washington DC, where it's lobbyists)....are these..

motor inside driven by actuators(hard to check without tearing maching down almost to skeleton)

gears that interact with those mechanisms(can lock or bind, from wear or calcification)

loss of power to entire unit(from input cord).

so, with that, methinks that some of what you've seen here is fine. The real question I have for you, are you intending to tear this item apart?

Or are you the sort that likes to have a professional on hand for the messy efforts?

Let us know, and we may be able to either get you some repair assistance(did you check the repair listings here?)

or you may find that a schematic, a screwdriver, and a cold ale, will go a long way to making this work forya,

now..it's your turn. What's your pleasure, ma'am.

and thankya for using fixya

Hello,

Yes, you need to adjust the knob that controls the amount of maximum humidity the unit will saturate the air with. The unit may be pointed in a direction that isolates the ambient air surrounding it incorrectly. Move it so the air points to the center of the room with no obstacles in its way of airflow.

If it is in a location that aerates an entire room with no obstacles in its way and the air saturation control is set to its highest setting, then when the unit stops it is because the humidity in the area immediately surrounding the unit is saturated but areas distant from the device are not.

If you have a ceiling fan in the room, set it for upflow and then a low setting. This will help keep the air in the room circulating. Otherwise a small fan pointed at the ceiling somewhere will accomplish the same thing eventually. This mixing from a ceiling fan or small fan takes some time to get the air in the room at even saturation.

If you have tried all this, please comment back with the Maker and model as well as serial number if you can find it. Please include the date of purchase as well and if you purchased this wit a credit card as it may double your warranty period

Then, I'll be glad to assist you further. OK?

Regards,
Worldvet

    Hello,

    Based on the myriad of responses you have heard and your now realizing your machine is not emitting any humidity because the wheels will not turn, you have two things plaguing your situation. Mineral build up on the bushing the wheels are mounted on and/or plastic gear teeth that have worn down and have caused the drive wheels to jam.

    You can empty the unit of water and see if you can manage to turn the wheels yourself to break the jam, while being very careful of your hands and wearing gloves. Protect your hands from being pinched accidentally.

    If the rods the wheels are mounted on have a lot of white crust on them you may have a frozen wheel due to the corrosion and they need to have the corrosion removed and be lubricated with the proper lubricant.

    If you can move the wheels yourself and they appear unjammed you will want to lubricate the section where the rods pass through the wheels. The lubricant to use is rather specific to your machine and you should call the manufacturer for advice on which lubricant to use and should the teeth on the plastic wheels have worn down to the point they jam easy, you will need to seek professional service from a company who has the facility to remove the corrosion, replace any wheels that need it and lubricate the wheels properly.

    Sorry, to be the bearer of bad news and sorry my first offer was off base and misunderstood. I would return it to the place of purchase and explain your problem. If they give you a stonewall to climb I would ask for a manager or supervisor. Then, you'll have to decide if the cost of repair outweighs the cost of replacement.

    Thank you for using Fix Ya and I hope this information is more clear.

    Regards,
    Worldvet

    Hello,

    Oh and by the way, there may simply be a set screw or bolt head that holds the drive wheel to the main motor drive rod. If you see one, turn the drive rod until you see a flat spot, position the main drive wheel over this and screw it won with a proper screwdriver to hex head which ever it is, if you don't know and this is the case describe it's look for me and I'll advise you.

If you have used it for a long time then minerals in the water may have built up somewhere and now needs to be removed wither by cycling a cleaner of some sort or physically scrubbing the moving parts yourself.  The first ting to try is unplug the machine, remove all the filters, and try cleaning with vinegar. Smells bad I know but following up by cleaning with a regular detergent should remove the smell. Detergent alone will not break up the calcium, the acid in the vinegar does that. Next we need to find out what gears may have slipped or if there is a belt out of place. If everything mechanical is in working order then the cam from the motor to the rest of the unit may be shucked in which case it would depend on where it is broken to determine the best repair. Please, if you could as some problems like this are not always simple, take a look at your particular unit and provide me with some further description of what is going on.

Hello, in order for the humidifier to turn on and off with the furnace you need either a sail switch or current sensing relay. A sail switch mounts in the return air duct and senses the return air when the furnace turns on thus turning on the humidifier and turning it off when the airflow stops. A current sensing relay works the same way but instaed of sensing airflow in senses current on the blower motors common lead and is easier to install than a sail switch. I will post a pic of both

Yes there is a thermal cutoff that will shut the motor off for a period of time to protect it from getting to hot. If this is what happened after 20-30 mins. the motor should come back on and run again.

Is rainmate good for sinus problems


If you are having issues associated with dry sinus, and it is cold where you are located (with heating unit running), then yes, a humidifier will increase the relative humidity of the air and possibly decrease the issues you have with dry sinus, regardless of manufacturer.
You need to look for a humidifier that provides for a decent humidification rate, in terms of gallons per hour. The higher, the better. And, with that, you want a decent water tank storage amount, or you will be refilling all the time (the smaller the tank, the more often you have to refill.).
Also look for a humidity control, but don't pay a lot for it. The more humid the air, the harder it is for more water to evaporate into it. You would really like around 50%-60% RH in your home.

My honeywell air purifier is emmiting an awful


Mine quit too... The led screen went blank so I changed the battery. Now it does nothing. I totally disassembled it as the fan was turning stiffly.(should spin very easilly) The grease in the end bearing was stiff. I washed the gummy grease off the shaft and reoiled with synthetic oil. Your smell is probably motor windings overheating. I disassembled the electronic control and was disgusted to see that there is a glass fuse soldered to the circuit board. I believe the only reason for this fuse is to cause us consumers to needlessly replace otherwise good equipment. (It cost more to pay a repairman to replace the hidden fuse than to purchase a new unit)The fuse is not blown. At least this fuse actually looks lide a fuse unlife the stealth fuses most electronics have hidden in them. I can not obtain a wireing diagram on my 17005 unit but it has a black box inside behind the control panel. It looks like a small start capacitor, but it has a temp rating on it of 70*C. I suspicion it is a single use over heat safety which triggered when my motor got hot due to stiff bearings. I refuse to play their game and purchase a new air cleaner. I love this one... So, if I can not determine what that little black box is, I am going to bypass all the crappy electronics and just drill a hole on top by the handle and install a hi/lo/off manual switch directly to the motors wire hasness. This machine will never give me problems ever again, and if I oil the motor every couple of years with synthetic (Ander oil) this unit WILL last me for the rest of my life...

I have the same problem. The one thing that I DID notice is that it seems to occur more often in winter. Thus, I attributed it to dryer air conditions--too much static electricity being the culprit.

Venta l44 motor won't run less than a yr. old


I own a 3-year old Venta L44 in which the motor stopped turning the wheels inside. It just sat there humming and eventually got hot. I sent an email to the Venta web site asking if they had a recycling program -- they don't. Instead, they replied (after a few days) stating that the motor was covered under the 10-year warranty. They sent me a new motor which was super easy to install. It didn't cost me a thing. It nows works perfectly.

Water wheels do not turn


Unplug the unit from the A/C outlet.  Turn the fan unit over, and with your finger, spin the fan as fast as you easily can.  Tooth like projections should rotate out of the lower most part of the assembly.  These teeth drive the wheel.  If they don't come out, the problem might be in the seating of that silicon rubber nipple, or the "tooth" assembly could be gummed up with algae and deposits.  You can wash it out.  The problem with mine is the teeth work, but the wheel still doesn't move.  I have emailed the sales office for help.  I love the unit's performance, but it is temperamental.  Good luck, and please post, if you fix it.
