Humidifier does not turn on


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

My dehumidifier is making a power surge every few minutes. why?


A dehumidifier is functionally the same as an air conditioner. It has a compressor motor, which is a fairly high current draw item.

First of all, unless you are well versed in electrical repairs, you should unplug this unit and do not use it. This is a dangerous condition and a fire or electrocution could result.

One of four things is happening:

1) You have a wiring fault in the circuit your humidifier is plugged into. There is a loose connection in the circuit, causing a voltage drop, and the humidifier therefore has to pull much more current to start it's compressor. This is a very dangerous condition, as an electrical fire could result. Try plugging the unit into another circuit and see if it does the same thing.

2) the compressor of the humidifier is going bad and is shorting out internally. Time for a new unit.

3) Many compressor motors use a 'start capacitor' to help the motor get going. If this part has failed, the motor will try to start, but it will not be able to.

4) There is a fault in the power cord or controls of the humidifier. Just like #1 above, a loose connection could cause a voltage drop, making the unit draw high current.

most of these units are standard 110V units. If yours uses 220V (like an electric dryer), then it could have 'lost a phase' which is also a similar electrical issue.

Humidifier Fan Doesn't Stop


RH at 70 % seems to me a little excessive you really should be working somewhere around 50 to 56% the fan has to move Air through the system.
I would like to know your room Air temp what is the Air temp comming off the system. what are your parameters.

This unit has had a lot of problems. It has come up in other forums. The fan motor is thermally protected. Could be the printed circuit board is bad. Check out this forum:

De Longhi DE220 De-Humidifier not collecting water


Hi there - you have to vacuum the filter several times. You can pull it out of the back left hand side of the unit. Vacuum it several times, and then start the unit on the lower fan setting, at a humidity level of around 60%. It will kick in after a bit, and then you can start adjusting the humidity level to where you would normally use it.

Sometimes - after you have vacuumed the filter, it still doesn't work. I used my fingers to pick lint off the filter, and ran a BIC safety razor over it as well, to try and get more out of the filter. You can also wash the filter in warm water, and leave it to dry over night. Don't put it back in until it's completely dry.

This will work! Cheers... E

Humidifier Runs but no water collected


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...
