Question about Skuttle 55UD Humidifier

1 Answer

I have a skuttle 55-ud humidifier. I know that there is a small hole that gets clogged from my hard water. What I can't figure out is how to unclog it. How do you get to it? I take the solenoid off but it doesn't seem like anything else comes apart.

    I take the solenoid sleeve off. It just has one nut holding it on. My question is how do you get the plunger out that the solenoid moves? The plunger is the part that has the hole in it that I need to clean, right? It has a flat head screw driver slot on the end of it but it won't move at all. It's barely two years old it can't be that stuck so I don't want to force it even though I tried pretty hard.

The hole that gets clogged is the solenoid one - it's the one that control the water flow. The only way to clean it is with a sharp , pointy instrument - you manually remove the lime deposits from the intake and outtake water connectors. Make sure to clean as well as possible the interior of the water passage thru the body of the solenoid - use a nail if necessary to scape everything from there.

    Yes, that is the input hole you need to clean, on its side, it should have a filter attached to it. The output hole is at the top, you should also clean it. If you can't move the water plug by hand (which is odd, the effort required should be very small) you must check if the solenoid is still operational: just activate it by connecting it directly to the transformer. If it doesn't open then it has been completely clogged by deposits. The only way to clean it is to submerge it while powered in hot vinegar.

My humidifier is not working first times worked great

The manufacturer states you can use tap water in these devices, but then goes on the disclaim that if you have water with minerals or hard water then white "dust" deposits can occur. Theses deposits are supposed to be noted and if seem, you are to change to filtered or distilled water or purchase one of their filter cartridges. These devices use very tiny holes to produce the mist you get out of them. It takes almost nothing to clog them. You should always use distilled water in these devices to prevent clogging. They also require very regular cleaning to stay clean and thus prevent them from becoming mold fountains. White vinegar and water should be used for cleaning. Avoid detergents as they can gum up the inner workings of the unit.

Unclog personal humidifier doesn't work

If this is an ultrasonic humidifier, in the bottom of the humidifier is a little disk that vibrates to turn water to vapor. This gets covered in mineral deposits and won't vibrate properly. They usually suggest something like vinegar to clean it. I found that this didn't work for me. What did work was cleaning it with my Waterpic on the highest setting. It chipped away the deposits and allowed it to work. HOWEVER, once you get it running again, buy the slant fin mineral absorption pads to keep it running. If you have mineral-rich water like me, you'll go through them quickly, but you also won't have white deposits on your walls anymore.

No water flow through solenoid

The water flow through the humidifier is limited/controlled by an orifice. This small opening can easily clog. After disassembly use a small wire to clear the debris trapped in the small hole,

Hope this helps?

My furnace is about 5 years old and the humidifier(skuttle190) has not been used in several years. I just ordered a new filter as the present one that I have does not fit properly on the wheel, its too...

Hello, if this is a drum type humidifier the small motor that turns the drum might be bad, take the drum off and see if the small shaft of the motor turn without the drum on it. if it does not turn than most likey the shaft or the internal parts of the motor are craked and must be replaced. If it does turn without the drum on it than either the filter is causing the problem or the drum is not seated properly. I hope this helps

Can the solenoid valve be taken apart?

no not the valveitself but if you know you are getting water to the valve there is a pin hole sized orifice in the tube that comes out of the valve that clogs easily

Unit blows air but doesn't dispence water

If you know you are getting water to the water valve, check the out put tube that goes into the humidifier, in the end of the tube that attaches to the valve the is a metering fitting that has just a pin hole opening to restrict the water flow, it is probably clogged.

No water going to humidifier

Easy fix: Check the solenoid. Turn off the power to your humidifier and the central air unit. On the side of your humidifier is a brass solenoid. It can get clogged with lime and calcium. Most videos and instruction manuals tell you to replace the solenoid. No need if you can turn a wrench.

1. After all power is off turn the water off to the humidifier and disconnect the top line water line at the nut.

2. Disconnect the bottom line water line that will go to your humidifier.

3. Take a Philips screw driver and remove the two screws that hold the solenoid on the side of the plastic housing of the humidifier.

4. Leave the wires connected unless you need more room to work. If you disconnect the wires then label them with tape (colored) so you put them back on correctly.

5. In the inlet or outlet water pip of the solenoid is a trainer that may be clogged. With a paper clip pull it out and clean it. If it’s clearly clogged then stop and put all back together. That may have been your problem.

6. If it’s not clogged then it may be clogged inside the solenoid.

7. The nut on the end of the solenoid is silver. Take it off and the magnet (main power unit) will slide off.

8. Notice the flat head screw post on the end of the solenoid. Turn it and remove. Be careful as a small spring loaded plunger is inside.

9. Take apart and clean all parts. You should be able to blow air in the intake water line tube and it go out the out water line tube as well as were the plunger hits in the center of the solenoid. If not then it’s clogged.

10. If clogged then just soak all but any parts with rubber or plastic in a small white vinegar solution for a couple of hours to eat away that lime. If it’s not clogged then you probably have a bad solenoid.

11. To check and see if the solenoid is bad just put it all back together but do not re-wire the solenoid to the humidifier.

12. Turn on everything without the wires going to the solenoid (turn on meaning put power back to the unit.

13. When the system is running as it should without the humidifier and solenoid wires attached check the two lead wires with a volt meter for 24v. If you have 24v then you have a bad solenoid and need a new one. If no 24v then you may need a new control panel.

Hope this helps you out.

The Hunter 33202 uses a recirculating pump to keep the aluminum mesh wicks (filters) wet. There is a vinyl hose which runs from the pump outlet to the top of the main unit (you will need to lift the main unit off the base to see any of this, much less do anything to fix the noise). The top of the hose meets the diffuser, which has several small holes to drain into that V-shaped double trough (located directly above the two wicks) which has larger drain holes on either side. If any of the holes in the diffuser or the trough become clogged, the other holes will tend to release a higher volume of water, which could lead to that running faucet sound. The clogs are easy to dislodge-- they're usually mineral deposits from the water. Another likely cause is the filters becoming clogged from dust that's being sucked in from the fan. Easy fix, also-- remove the wicks every week or so and thoroughly rinse them under running water.
