Question about Lasko Humidifiers

Open Question

My Lasko 5000L won't work.

I changed the filter on my humidifier. The filter was full of lime. Now the light will not come on and the water will not flow thru the filter. It seems to have power because I can hear it click when I turn the Humidstat. I think it stopped working long before I changed the filter. There is water going up to the units control. Can anybody help? The unit is about 2 years old and I can't find the manual.

SOURCE: No Water flow thru Humidifier

Loosen the brass fitting where it connects to the soleniod valve. If water comes out your saddle valve is ok. Carefully retighten this fitting. With the humidifier turned on loosen the first fitting down stream from the valve see if water comes out. if it does turn the humidifier off and see if it stops, it should. That will tell you the the valve is ok then, just clean the filter and the oriface. if it does not turn on and off check the wiring. if ok replace the valve.
Good luck

SOURCE: The humidstat light is on when I first try to get

This is normal, based on where you have the humidistat knob set to, it will go out only after reaching the humidity level set on the knob. Also if you have it setting in a fairly large open area of your home, it may take a loooong time to reach the proper humidity level. My cousin has one of these units setting in his living room, which has a cathedral ceiling, the unit's humidistat light never goes off, and the unit runs continually, unless the resevoir runs low. But the unit operates fine.

Hope this answers your question. You may refer to your user's manual regarding this, or if you don't have a copy, you may download one at this link: http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000006709.pdf

SOURCE: I have a aprilaire model

I installed a new unit, and the fan and solenoid would not operate. I checked that the board H leads closed during test, all the wiring continuity, and the solenoid by applying 24vac to open and close it. Because components checked, and wiring checked, I finally looked at the connections to the fan, at the current sensing relay switch. The human error was a loose spade connection from factory assembly! Once all those connections were tight, the unit is functioning properly.

Lime scale build up and slime in bottom of filter tray


If your water is suddenly evaporating into limescale, your local water company may have switched to a different water source, or your water softener device is out of salt. The limescale can be easily cleaned with vinegar and a sponge, but this will keep occuring unless you use water that doesn't contain disolved calcium. Try getting an RO water filter and use that water.

Water leaking / running from top of humidifier


humidifiers have a drain and if there is water going in it will be coming out the drain. check drain to see if it is clear, check hoses going into top of humidifier for cracks, check filter in humidifier.

Lime build up on coil has to be cleaned weekly how do i prevent so much and many times cleaning the coils is their a additive i can add or device to prevent


You could add an inline water supply filter. That would help some, since it appears you have a hard water situation. A 50/50 solution of white vinegar and water will clean the existing lime scale. Adding a whole house water softener is also a good solution.

Hope this helps solve your problem.

Blowing air, no mist and there is no diference between on full blast or on low


From the troubleshooting section of the manual (http://www.crane-usa.com/manuals/HumidifierManual2008.pdf):
The power light is green but there is no mist being emitted: ? Check that there is water in the tank. ? Check for possible lime deposits on the water level sensor or the nebulizer (see page 8 and 9). ? Make sure that nothing blocks the vapor output slots. ? Check that the fan vent on bottom of humidifier is not blocked. ? Empty the humidifier and rinse the water basin with cool tap water and allow to dry for 15 to 30 min.

GET NO FLOW. CAN FEEL THE SOLENOID GETTING POWER AND CLICK


I would suggest that you locate supply valve to humidifier and loosen compression nut on outlet side to see if you have water at that point. If you do shut valve off and disconnect supply line on incoming water line and make sure it is clean. Check for plugged screens or lime build up. Clean as needed. If you aren't getting any flow thru shut off valve then turn off water supply to the valve and replace it. I hope this helps you. Thanks

Our aprilaire humidifier is only 4 years old and it does not seem to be working. We have static in the house and when I did test mode it never drained water like it was supposed to. Any ideas what I can do...


Hope this helps, check and see if humidistat is set to 35% humidity and that bypass damper on humidifier is in the open position or winter position.(humidistat is usually located on cold air return duct near furnace). Next, replace humidifier media pad, remember to replace media pad (filter) annually, you also may want to clean any lime deposit out of humidifier housing with a solution of warm water and white vinegar before installing your new media filter.Remember to turn power off at side of furnace when cleaning humidifier and replacing media. Before installing new media turn power back on to furnace, set humidistat to the on position, turn furnace thermostat above room temp., and inspect humidifier to see if water is running from top,(you may want to have a bucket under humidifier when checking for water), if you see water running, turn power back off to furnace, properly install new media filter, reconnect humidifier cover & set humidistat to 35%. If you do not see water present, check water supply valve to humidifier and make sure its turned on. If water supply valve is open, then check water supply tubing for blockage.And the last things to check is to make sure all registers through out your home are open and not blocked by any objects, also make sure furnace filter is cleaned, if none of this works refer to installation manual to see if humidifier was sized and installed properly, Good luck.
