There is ice on the filter and the filter will not come out. Tried turning off so it would melt, but filter still stuck. It is summer so why is ice forming?


I have had a AD75UST0 WHIRLPOOL Dehumidifier for several years. I had mine ice up once or twice particularly on very high humidity days > 90%. Once it thawed out. I was able to remove the filter. Most likely it is due to dust getting on coils & condenser Or actually has a Freon leak. to resolve the dirty coils you can easily dissemble (that is remove front & rear cover) it to give coils and condenser a good thorough cleaning. It the coils and condenser are not at all dirty, then is not the cause of the icing. The units are typically not serviceable - i.e. a disposable small appliance.

The compressor and fan are running, however, there is no water coming out. RH is 70, temp is 66. This is after replacing a blower that had already seized up 2 years ago.


The dehumidifier should be removing water at 66F 70%rh.

First make sure that the compressor and fan are running. If they are, then turn the dehumidifier off and unplug the cord from the wall outlet. Next remove the front cover from the dehumidifier. Examine the evaporator coil (about 1/2 way up) beneath the plastic heat exchanger and above the stainless steel drain pan.

If the evaporator coil is cold and completely covered with frost & ice, the defrost thermostat may be defective. Replace the front cover. turn the humidity dial to "off". Plug the dehumidifier in to the wall outlet and set the fan switch to on - the fan will run (no compressor). Run this way for one hour to defrost the evaporator. Now adjust the humidity dial to your desired humidity and keep an eye on the dehumidifier. If it freezes up again and does not automatically defrost, the defrost thermostat should be replaced. Call the manufacturer at 1-800-533-7533 for parts and instructions.

If the evaporator coil is (mostly) warm and free of frost and ice, it is likely that some of the dehumidifier refrigerant has leaked out. this type of service should be done by a (refrigerant) certified technician. Call the manufacturer at 1-800-533-7533 for help with this service.

The coil is freezing. While it may be a freon problem, isn't there a thermocouple on the coil to detect freezing? Do these things go bad?

Error Code CH 01


I have a Comfortaire BHD501 dehumidifier. A couple weeks ago I noticed ice building up on top of the unit,so I unplugged it to defrost. I plugged it back in and it worked until I noticed the "CH" "01" code. It would run a few seconds then shut off with that code showing. I took off the front of the unit and noticed rust on some of the metal parts. Then I took the cover off the circuit board for the front read out. I noticed corrosion on some of the solder points. When I looked closer at the plastic cover for the circuit board I noticed a small burn mark. The water from the melting ice must have run behind the cover and shorted out the circuitboard. At this point I don't know if new boards are available.

Dehumidifier -- LG LHD45EL


If everything is clean on the coils and the filter is clean it should work. I would contact LG because they have a 5 year warranty on these dehumidifiers. Make sure that you have your reciept. Usually what they will do is locate a shop near you and it can be serviced there. LG will pay the bill. Or if there is no local shop they will send you a service tag for your old unit and ship you a replacement unit. Contact LG and explain this problem to you. Everything should be covered under warranty still.

Good luck - Tech101
