Why when I turn on my humidifier does it blow a fuse

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

If the fan is barely turning, it could be the fan is bad. This fan blows air across a 2 coils.

if it's working well it should , unit should be removing all the moisture from air expelling out back , so its dry air

its when coils freeze up then you have a indication of problems

Hello,

yes, its normal.

Apart from the heated air blowing out, do you notice any kind of fault from the unit or is it malfunction in anyway as a result of the heat?

If the answer to the above question is NO, then there is noting to worry about.

Take care.

It's probably a common problem with these models: the fan motor causing a thermal cut off fuse to blow. I have the same problem. See this link on another site: http://forum.doityourself.com/humidifiers-dehumidifiers/177549-kenmore-dehumidifier-fan-stopped.html

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.

It's on the right side under blue plastic cover.

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...
