Humidifier gets ice on top of cabinate. It still produces water.

if your saying that the voltage drops to around 4 volts at the supply transformer at anytime , then id say the load (device connected) is too much for the transformer to supply this most likely is caused by an internal fault in the load (humidifier) also since its a water appliance id say a water leak might be a factor in that as well , taking a look under the cover of the humidifier 4 signs of a water leak (or past one) would be where id start

It sounds like the feed has been shut off or pluged. Be sure the feed is off, remove the feed from the humidifier. open the fill valve slowly and run water into a bucket or whatever. If it does not run you found the problem, if it does then it is probably the fill solenoid valve on the humidifier.

Kathryn, if you are operating it in a basement application, the problem is that air temperature at floor level, is colder than at shoulder level. Dehumidifiers struggle to work at temperatures between 40 & 65 degrees F (Unless they are Low Temp model designed for basement applications). And will ice up at times. Raising the unit up off the floor onto a sturdy table, counter top, etc that can handle the weight of the unit, plus a full bucket of water, will usually resolve the problem.

If it's not a basement application, try lowering the humidity extraction level to 35%. In you have an analog unit, turn the control knob to Maximum.

I hope this helps you and thanks for choosing FixYa.

Hi,

Here is a tip that I wrote that will help you understand why and what you cando with a dehumidifier that ices up.

Dehumidifier is Freezing up and not working

Hello,

If there's no water in the reservoir, first make sure that water is getting to the humidifier. The humidifier must have a good stream of water available to it. If there's water in the water line but the reservoir doesn't fill, replace the float mechanism inside the humidifier.

Take care.

Basically there is a drainage blockage from the humidifier to the bucket. Take one for the boys and **** hard on the pipe which very possibly will release the blockage.

fill with water - the water conducts electricity and in a few minutes will produce steam

Are you talking about a dehumidifier or a humidifier. If you are talking about a dehumidifier, it works by blowing air across a cooling coil causing condensation and the water will drip and pool. The cooling is caused by a compressor working like refrigerator, but using the effect to dehumidify. To check if the cooling coil is working there will be a metal can like in it with tubes in and out. One of the tubes should be warm(input) and the other tube should be cold, if not your compressor is not working. If freezing up, low freon. Check to see if the compressor shuts off very quickly, that would be too much freon. This is not user servicable. Now a humidifier works several different ways. One way is a fan with cloth belts rolling through water using evaporation to humidify. Another way is for a circular fan like on a motor to turn. It has a hollow piece into the water. It picks up water and then through centrifugal force aerates. One way is for a sonic humidifier. All the types have a problem with eventual calcification or mineral build up in the water handling paths. Lime-away or Concentrated Lemon Juice will dissolve this. The lemon juice is the most fun. It will turn your toilet bowl white and also remove rust stains from laundry...
