Humidifier ., condenser system ok but fan fails to run.

its going to drip when it is off,it has built up humidity and has nowhere to go,leave it running and let it cycle by itself or cause damage to the system

the condenser (air intake) is blocked, most likely with dust, and the fan isn't passing enough air flow. either the fan is overworking and making noise or the compressor is overheating. if it can't cool down, the evaporator (cold coil) won't get cold enough to collect condensation. unplug the unit, take it outside, open the front, and hose the condenser down. if you can see light through it, it's ok. if not, spray some simple green degreaser on it and hose it down again after about 5 minutes. if you have a stiff bristled brush, use that, too.

clean the condenser in the front or the filter if it has one. no air flow to cool it down will result in overheating and no condensation collection across the evaporator coil.

My brand new frigidaire 50 liter dehumidifier has been on for two days and has not collected water from my damp basement. It is on the factory settings: high fan and "CO" (continuous).

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.

ok Carmo

first remove the back of the unit and turn it on. it sounds like the fan motor may not be working.there by making the dehum get hot. make sure your filter and coils are cleaned. you may need a new motor. if so buy a new motor and fan blade.be careful with the 5/16th nut holding the fan blade. the blade might look good but you have to check the hole where it rides on the motor shaft. if you into the hole it should look like the letter "D" because the motor shat is shaped that way.---good luck

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...

check compressor is running
