Don't blame the xhildren, or any of the children either, it's not their fault. (Sorry, couldn't resist) Placing a book on top would have no adverse affect on the dehumidifier. Have it checked at a repair service provider. Bring a copy of your proof of purchase if possible.

We just bought a new Friedrichs dehumidifier for our damp basement. The temp is reading 81 and the humidity 63 and it's been running for 2 hours. The basement is about 1000 sq feet and the outdoor temp...


Iris, all dehumidifiers generate some heat while in operation. However, it may be generating higher temps because of it's location. Dehumidifiers don't work well in temperatures below 65 degrees, In fact they struggle below that temp. Unless it's a Low Temperature unit, designed specifically for basement applications.

For example, the ambient air temperature never changes more than 10 degrees F throughout the year.
The air temperature at floor level (where the dehumidifier is placed) is colder then the air temperature at shoulder level. Raising the unit up off the floor onto a sturdy table, counter top, etc, that can handle the weight of the unit, plus a bull bucket of water, will generally solve the problem.

Be sure to clean the air intake filter regularly. At least once every 2 weeks. And wipe off the cabinet and the front louvers, when you change the filter. Always, turn the unit OFF & Unplug it, before removing the filter. Never operate the unit without the filter in place. Doing so could cause damage to the unit.

I hope this information has helped you and thanks for choosing FixYa.

My GE basement dehumidifier is overheating. The bucket still collects water and the fan works, but the unit is putting out alot of heat. My dad is visiting and has taken the whole thing apart. Any...


Yes, the first suggestion is I hope your dad can get it back together without any parts left over (LOL). Over heating is generally caused by an clogged or dirty air intake filter. Simply removing it and vacuuming it or if it's really dirty, washing it in warm water and mild dish washing liquid will clean it. Rinse it thoroughly, shake off excess water and allow to dry completely. Never operate the unit without the filter in place. Doing so, can damage the unit.

Getting back to the heat for a moment and where you're using your dehumidifier. Dehumidifiers do generate heat, it's not abnormal. Operating it in a basement can cause it to over heat. This happens because the air temperature at floor level is colder than at shoulder level. Dehumidifiers struggle in temperatures below 65 degrees F (unless you have a Low temp unit, designed for basement applications). Raising the unit up off the floor, on to a sturdy table, counter top, etc, that an handle the weight of the unit, plus a full bucket of water, will generally resolve the problem.
Actually, a basement application , higher is better.

There are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder
level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this helped you to troubleshoot and solve the problem. Thanks for choosing FixYa.

Coils freeze up. completely blocked. have to shut off to thaw coils. located in basement.


After the unit is totally thawed and dried, turn the unit Off if you haven't already and unplug it. Remove the filter and clean it. If it's really dirty wash it with warm water and dish washing liquid, thoroughly rinse it and allow it to completely dry, before reinstalling. DO NOT operate the unit without the filter in place.

Because the air temperature in a basement is colder at floor level, than at shoulder level, this caused the coils to freeze. Dehumidifiers do not work well at temperatures at or below 60 degrees F. That is, unless, it's a Low Temperature model, designed especially for basement applications. Obviously, yours isn't a Low Temp model.

To overcome this, place the unit up on a sturdy table, counter top, etc, that can handle the weight of the unit, as well as a full bucket of water. The higher off the floor the better. This way, the ambient operational temperature will be higher and the coils will have less of chance to freeze again.

I would suggest that continue to monitor the unit and if you notice that it's doing more than a little frosting on the coils, turn the unit OFF immediately. A little frosting is normal and the deforst mode should kick in and thaw the coils. When this happens, the compressor should automatically shut OFF, but the fan will continue to run. Once it's defrosted, the compressor will start again, if necessary.

I hope this helped you to troubleshoot and solve the problem. Please let me know.

How do I change the air filter


To remove the filter:
1. Turn the unit OFF & Unplug it from the wall receptacle.
2. Remove the water collection bucket and set aside.
3. Just inside the water collection bucket holder at the top, you should see the a plastic frame
behind the front louvers of the unit. It may have a plastic pull tab. That's the filter.
4. Pull it straight down and then remove it from the unit.
5. Wash it in warm water and mild dish washing liquid. Rinse thoroughly and dry thoroughly before
reinstalling it. The filter should be cleaned regularly. NEVER operate the unit without the filter in
place. As this can cause damage to the unit.

Hope this helped you. Please let me know. Thanks.

It keeps getting ice build up on the outside, on top, in the front.


Several things can cause this problem. So, I'll start with the most common first

1. Dirty or clogged air intake filter. Remove and clean the filter per the Owner's Manual directions.

2. No enough clear air space surrounding the unit. Maintain a minimum of 12" around the entire unit.

3, The ambient air temperature at floor level is between 40 & 60 degrees F. This usually happens in basement applications. The air temp at the floor is just to cool for the unit to operate as it should. Place the unit up on a sturdy table or counter top, that's strong enough to handle the weight, with a full bucket of water.

The more critical things would be - Low refrigerant gas in the cooling system and the compressor needs to be recharged. Or the Defrost Cycle Sensor has failed and the unit has frozen up.

In any of the above situations, you should turn the unit OFF and unplug it from the wall and allow it to thoroughly thaw, before attempting any maintenance I described above. You should put some old towels under the unit to absorb the water as the unit thaws out.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

Danby dehumidifier ddr4588ee ices up. Humidifier located in basement with temp around 60degrees. Unit is 1 1/2 years old.


According to your Owners Manual, the coils may start to frost at 60 degrees and the defrost sensor should turn ON and cycle periodically. However, the air temperature at the floor level in a basement, is colder than the air temperature by 5 to 8 degrees. So this may be causing the problem. In addition, if the air intake filter is dirty or clogged, the unit has to strain to keep up and will not function as it should.

If the unit is totally iced up, turn the unit Off and unplug it from the wall outlet. Allow is to thaw completely before attempting to clean the filter. You may want to put some old towels under it while it thaws. Once it's thawed, move it to a bathroom that has a shower. Plug it it in and set the humidity level at 45%. Turn the shower ON at a Medium hot temperature (enough to generate steam) and as you exit the batroom, close the door. DO NOT operate the bathroom's exhaust fan. Allow the unit to operate for 15 to 20 minutes, before returning to the bathroom. Then turn the shower OFF and check the unit for any frost and the amount of water collected in the bucket. If there is no frost on the unit and there's water in the bucket the unit is operating properly.

When you move it back to the basement, place it up off the floor on something sturdy, that can hold the weight and not be bothered by the vibration of the unit, when it's running. (ie a work bench, a counter top, etc.) Operate the unit as you normally do and monitor it for frost or icing up. And, whether or not the defrost sensor is cycling as it should. If you get no frost or just minor frost, it was the air temperature at the floor level, that was causing the problem.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

My dehumidifer is freezing up what could b wrong


If the air intake filter is dirty, that can affect the operation and cause it to freeze up. Operating in temperatures below 40 degrees will also cause it. Or a low refrigerant level can also cause it. Turn the unit OFF and unplug it. Place some old towels under the unit to absorb any dripping water. Once the unit has completely thawed, remove the filter and clean it. Carefully replace the filter (be sure it's dry) and give the unit a try.
