    Hi, I have a Frigidaire Model FAD704DWD 70 pint dehumidifier.
    I have had this for 2 months now.
    But, a few days ago it started to display 88 on the display.
    Sometimes a number 99.
    What does that mean?
    Thank you

    why does the Dehumidifier FAD704DWD keep showing a 99 and a 88 code?
    those codes are not shown in the owners manual??
    thanks

    Thanks for the info on your website! The question I have is regarding the amount of water that a dehumidifier can remove.
    I want to install a dehumidifier in a small bathroom with no ventilation. The bathroom gets mold on the walls because of this. What size should we be getting? There is not a lot of space, but the smaller units do not extract a lot of water (measured in ounces and not pints), and I’m concerned that the smaller units won’t extract enough water.

    Thank you

      Sorry, what I was I was trying to get at with that poorly-phrased question was that I’m trying to come up with a very rough idea of cost per day to run a dehumidifier. If dehumidifiers pull an average of 570 watts when running, and let’s say I assume it runs 8 hours per day on average at that 570 watt level, and my electricity costs 15-cents per kwh (kilowatt hour), can I translate that into cost per day with this equation?: [(570 X 8) divided by 1000] X fifteen cents = ~ 69 cents per day. I realize from your articles that there are many variables that make actual cost to run impossible to calculate, but I’d like to at least estimate it using those assumptions.

    Hello. You have a great, informative website here! I have a 2014 Frigidaire FAD504DWD unit that I brought over from my parents house. It worked well last summer but now it always seems to have the compressor on and generate heat whether the fan is on or not. I turn it on and set the humidistat to 50. The fan runs for a brief time, then shuts off and the digital readout is “30”. Am I just now noticing the auto-defrost capability, or is this unit malfunctioning? Thanks for your assistance!

      It sounds like your unit is malfunctioning. I advise calling the manufacturer to troubleshoot the issue.

    I read & comprehend why using a larger than needed 70 pint for the size room is more efficient to run and less costly than the 50 pint Frigidaire. I want to determine if this concept would still apply to only roughly 310sf space with medium to high summer humidity. It is a storage style building made livable efficiency. Due to age of building the construction materials and insulation is poor and shower area not adequately ventilated. This and Oklahoma summers lend to its humidity issues.

    Hi,

    You have an awesome blog here, convinced me to get a 70 pint over 50 pint.

    My question is what is the energy-efficient and proper way to use the dehumidifier every day? I don’t want to leave it on 24 hours/day and don’t feel the need to. However, should I set the 70 pint dehumidifier to 50% and leave it on for 1 hr every day? I’m not sure what’s the best way to use the dehumidifier.

    Thanks,
    Chris

      The dehumidifier will automatically shut off when the room reaches the desired humidity level so you can leave it on 24/7 and it will only run at full power draw when necessary.

    Hi,

    I’m using the Frigidaire 70 pint degimidifier to dehumidfy an area of 1,100 SF. The equipment took a lot of time to go from 80% to 55% RH. Once it reach the set pint it shuts off for about 10 minutes when RH rises to 60% and keep workong for about 25 minutes. It seems that in an hour it is working for 50 minutes. If I project these to a 24hr period (please, correct me if I’m wrong) the equipment is on for 20 hrs. That represent a lot of consumotion. Here in Puerto Rico the kwh cost is 22 cents and is expected to increase. If I put another 70pint dehumidifier what energy consumption should I expect having both working together? Half less (say 10 hours on?) if so, the cost would be the same as there is the double of energy consumption. Please advise. Thanks in advance.

      In your case we would look towards better insulating the environment where the dehumidifier is being used and/or working to remove the source of the humidity if that’s applicable here.

    I question the effectiveness of packaged desiccant dehumidifiers used in clothes closets and similar closed spaces. These spaces are clearly air permeable. They leak around doors and possible through their walls. Outside humid air intrusion will be a continuing action. The desiccants will rapidly reach their saturation point and lose any possible effectiveness. I find the recommendation and advertising of these products misleading. In a hermetically sealed enclosure they would be expected to work.

    • Admin says

      Yes, humid air will leak through but not fast enough to make much of an impact. Small desiccants do work effectively in very small spaces like closets.

    Our new house is on top of a cross space. The cross space is large. I myself are able to access it. I have a HISENSE UNIT. SERIAL# K-GG1YJ0580.
    I was going to place the unit in the cross space to dry it out. In the cross space is sealed with heavy plastic. Would it be advisable to use the unit for that purpose?

    Thank You
    George

    I am so grateful to have found your site. We designed and had our small (1650 sq. ft.) home built just 10 years ago. There have been problems since the beginning of the second year with incorrect air conditioning installation resulting in mold in nearly every corner and ceiling in the house. The a/c duct work and the handler have all been replaced brand new TWICE!. Mold inspector/s have thoroughly tested the entire house for evidence and all had the same opinion … lots of mold everywhere behind gypsum walls and ceilings. Did not have the option to move out after the financial investment so have cleaned and tried everything reasonable recommended to us. Ceiling fans, return airs and light fixtures have mold accumulation and have to be cleaned very frequently.
    We should own stock in the DAMP RID company because we keep two hanging ones in every closet and several in the containers in each room. (They are dated when placed and very seldom do they go past 4-5 weeks without requiring new ones!
    The master bedroom, closet, bath and laundry on the north side; kitchen, living & dining in the center and the guest room, bath and office on the south. Just this week it was pointed out that we really needed to get a couple of dehumidifiers (one for each side of the house). Do we get two 50 pints or one 70 put just in the center?
    I’m sorry to be so “wordy” we just need to resolve the problem as best we can. The house cannot be leased or sold until the problem is completely eliminated.
    Thank you for your wonderful guide, but I still need more specific direction. Carolyne

    Gravity drainage I am getting the bucket filling up same time as the drain to floor. IS this possibly caused by lack of fall or gravity?

    We live in coastal Carolina. Our house is 3000 sq feet built with a crawl space. crawl space iis currently enclosed (previous owner did this) and the Advance dehumidifier just broke.
    What would you recommend to replace it? Someone said to get a unit with ducting….. very confusing.

    Hello,
    I have two young children under 4yo and they love pushing buttons and shutting off the deep freeze etc. Do you recommend a dehumidifier with a “child proof” feature so they can’t shut off the unit? Or a wall mounted dehumidifier?

    Thank you for all your thorough reviews.

  14. Marianne says

    My 2000 sq ft house has an average humidity around 50-52%, but the large bathroom, small enclosed laundry room, and the large bedroom between the two have a higher humidity than the other side of the house, which negatively affects my chronic neurological condition.

    I don’t want to get the whole house so dry that it aggravates the children’s eczema so am concerned about overdoing it. I do want to reduce the humidity in the areas most affecting me, especially during peak activity times. As it stands now, if my spouse showers first, I can’t shower after without being affected. If I’m washing clothes, I can’t then be active enough to hang them to dry in the same space.

    Would I be doing better to use multiple smaller dehumidifiers than to use one big one? My spouse is interested in humidifiers that are installed in the ceiling’s vent fan (if I understand correctly, and I might not) but says they create heat, which also affects me. This has left me without any dehumidification for years. I don’t believe what I have is the best it can be so I’m trying to learn for myself. What are my options?

    I own a Keystone Dehumidifier model number SD52PE and have a troubleshooting code of E6. What does this code mean and is it worth getting repaired?

    • Admin says

      We recommend that you contact the manufacturer directly with this question. A customer service phone number should be listed in the manual that accompanied the dehumidifier when you bought it.

    Hello,
    I just have a question about house size/dehumidifier capacity.
    I live in a yurt ( large insulated tent ) that is about 700 square feet, with a vaulted ceiling.

    I’m wondering if you could give me any advice on what size unit would be best suited for this space? Because of the nature of the building, it tends to be fairly humid.

    Thanks so much for your time. Your site has been fantastic. :)
