What is a dehumidifier?
A dehumidifier is a household appliance that removes humidity from the air. Since humidity can cause mold and mildew to grow, many households use the dehumidifier for health reasons. However, many times people do not know who to turn to when the dehumidifier stops working, or when there are other dehumidifier problems. Read below where some of the most common questions have been answered by the Experts regarding
What capacity dehumidifier is required for a 1000 sq. ft. basement?
The amount of dehumidification required is not solely dependent on the size of the basement. The part of the country where it is to be used and the amount of dampness will affect the size. A tightly sealed basement that restricts entry of damp outside air will require less dehumidification. In general it is best to check manufacturer’s specifications for the dehumidification capacity of different models and choose one size larger. If that is not completely effective, add another unit. If there are items that may be damaged by humidity, you can consider using two units so that if one fails there is a backup.
How do I clean the coils of the dehumidifier?
Start by using a narrow brush to remove the accumulated dirt and debris from the front and rear coil surfaces. Use a vertical motion to prevent any damage or distortion of the coils. Compressed air can also be used to blow away the dirt. Once this is done, spray an
coil cleaner on the coils. If these are not easily available you can use a degreaser or spray detergent. Gently pour water over the fins to wash away the dirt loosened by the spray. Be careful not to allow water to fall on to the electrical component or connections.
My basement is warm and the dehumidifier coils are clean but the dehumidifier stopped working and keeps freezing up. What is the reason and what can I do to fix this?
There are three common causes of dehumidifiers freezing up. The first is blocked coils which restrict the airflow and the second is low ambient temperature Most likely the cause is low refrigerant in the unit. Refrigerant leaks in the sealed system are not uncommon. Repairing this can be expensive – the service call could be in the range of $80, valve replacement could range around $10 and refilling the refrigerant may cost about $80 per pound. Even if you need less, most companies charge by the pound. It may be more economical to buy a new humidifier.
When I turn on my dehumidifier the light goes on but the unit does not start. What should I do? Is there a reset switch that could resolve the problem?
A dehumidifier not working is usually because of either a bad compressor or defective
. Since in this case the light comes on, it appears that the humidistat is working. There is usually an overload and capacitor on the side of the compressor which you can try resetting. But the most likely cause of the problem is that the compressor is damaged. If this is the case, repairing it is not a cost effective option and buying a new one may be better.
The fan on my dehumidifier is not working could the fan motor be burned out?
Before presuming that the fan motor has failed, you need to check if it is getting power. If you have a voltmeter, follow the two wires coming out from the back of the motor to where they end and check, with the compressor on, if 120 volts is being supplied. If there are more than two wires, follow the one that goes to a capacitor (a silver colored cylinder) and check the power supply there. If the power supply is there, that means the motor has gone bad. If there is no power supply, it could mean that a relay is defective and will have to be replaced. If you do not have a voltmeter, there is another option, but this should be done with great care and only if you are comfortable with it. Connect the two fan motor wires to an extension cord and then plug the cord into a wall outlet. If the motor runs, it is fine and the problem lie elsewhere.
My Honeywell model HDH-130 dehumidifier is running, but no water drains into the container. What could be wrong? Does this mean the dehumidifier is not working?
The most likely cause is a dirty condenser which more than likely needs to be cleaned. When a condenser is dirty and clogged it gets warm resulting a rise in the Freon pressure which reduces the evaporator’s ability to remove moisture from the air. Cleaning the condenser can be done by removing the screws around the panel and removing the front and back and then the “U” shaped side panel. You can now wash the dirt from the condenser coils. Check the condition of the removable filter as well, as a clogged filter can affect airflow, before re-assembling the unit. If there is no improvement, the Freon level may be low which is a repair that should be done by professionals. Since the cost of such a repair is high, replacing the unit may be a better option.
These are just some of the questions on humidifiers problems that Experts on JustAnswer have answered. Dehumidifiers are complex devices that operate on 120 volts. If you are not sure of your ability to clean or repair the dehumidifier safely, it is advisable to ask an Expert and get answers before you try to tackle dehumidifier problems in order to prevent injury or damage to the equipment.

We have a 400 sq/ft area of our basement that we're having finished to serve as an office/playroom in our home. We're having the work done professionally and to code to insulate properly for moisture ....
Being in Alabama, in the summertime, we tend to see condensation dripping off of some of our duct work. Our contractor is suggesting that we should install a whole-house dehumidifier, however, however I thought that we might only need to provide a dehumidifer for the one room.
Since the ductwork will soon be in a closed, climate controlled space ... am I right to assume that adding a dehumidifer to the space would help alleviate condensation from ruining the new drywall and ceiling?
SOmething like this perhaps?:
I was thinking we could duct it to an existing line or create a small duct circuit within a closet in the room that would cycle just the air from the basement room.
Am I completely off my rocker here?
Bought an 1170 sf ranch house in NJ two months ago. It has
Bought an 1170 sf ranch house in NJ two months ago. It has a model #92G1UH090CP16-02, serial #5911K33346. Since living in the house, there is awful condensation on windows (with mold now on sills), the underside of the attic wood sheathing is wet and there is new mold everywhere. There is only an exhaust PVC pipe on the furnace, but no intake pipe. There are end vents on the attic peaks, but the insulation has been packed down to the soffits. Could any of this be as a result of the furnace operation? Its only a couple of years old. I cannot find any water leak sources in the house. Is my only answer to open up the soffits and add a continuous attic fan? Seems like an inordinately high amount of moisture/humidity in the house now that its getting cold outside. Thank you.
