It sounds like the Dehumidifier has a problem somewhere on the circuit board. You could try and find a local humidifier repair shop in your area otherwise it may be cheaper to purchase a new replacement instead of having it fixed. Good luck.

When my dehumidifier is on, it says there is 90 humidity. I come back an hour later, it is still running and no water in the bucket.


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.

Start up instruction for dehumidifier


A dehumidifier does not need water in the tank.It takes humidity out of the air and the moisture goes into the bucket. A humidifier has to have water in the tank.Note ,a humidifier puts moisture in the air, and a dehumidifier takes the moisture takes moisture out of the air.

Adjusting dehumidifier on furnace


This model furnace does not come with a built in humidifier. Humidifiers are normally an optional add on. If you have a by-pass type humidifier it is none adjustable. Water level is normally float controlled and operation is control by blower circuit. When ever the blower runs the humidifier operates when in the heating mode.

Maytag M7DH45B2A freezing problem


Is this a humidifier or dehumidifier?

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...
