Dehumidifiers are devices that absorb excess moisture from the air using a rather simple principle that involves cooling and warming the air in order to condensate water vapors. Although their operating mode is not too complicated and they manage to do a very good job without causing too much hassle, there are times when they stop working or they become faulty. In order to avoid situations in which your dehumidifier will not be able to adjust air humidity at the highest standards, here are the most common troubleshooting tips.
The unit is very noisy
There are many reasons why the operating can become louder than it usually is and one of those reasons is that it hasn’t been placed on a plane area. If yours makes a loud sound while operating, adjust its legs until it will sit straight on the floor. Also, look for loose screws that could make noise and make sure all the covers are tightly screwed. Another reason for it to make a humming sound is dirt than can often gather on the internal parts thus, forcing the unit to work. By cleaning and vacuuming it, you will make sure it will work for many years to come.
The coils have frozen
One of the most often problems encountered in a dehumidifier is that its coils could freeze. Given that its working depends on the coils, it’s essential to keep them in a perfect condition but, unluckily, differences in temperature can create a layer of ice on the coils. If you place it in a room with a temperature that is lower than the one suggested by the manufacturer, the coils might freeze and the unit might stop working. This can also happen if you place the device on a lower level with a temperature that is lower compared to air level, so it’s best to put it on a higher level. Cleaning the coils every once in a while can also help prevent freezing. Use a simple brush to remove dirt from the coils and spray them with a mixture of water and vinegar.
There are leaks in the tank
Given that the tank is constantly being filled with water removed from the air, no wonder leaks might appear occasionally. If you don’t empty the water tank in time, water might spill and it could reach the important components. In order to prevent this, empty the water tank as soon as it gets filled and clean it very well to prevent dirt. If you will place it in a room with limited access, connect the drain to allow the water to evacuate on its own and prevent any tank leaks. Always check to see if the drain is clogged because this could also cause leaks.
The motor is no longer running
A dehumidifier’s motor is the most important component that is actually powering the device so if the motor is not running, neither will the dehumidifier. In this case, it’s advisable to get the unit to a professional who will know how to fix or replace it. If you are not an authorized technician, you should not try to fix it yourself because you could not only void the warranty but you could also cause more damage.
The fan doesn’t work properly
The fan that absorbs and ventilates the air could also be faulty after a while because it runs almost continuously while the unit is plugged in. If it stops working for some reason, check to see if any of the fan blades are broken or loose. Clean the fan and restart the device to see if the fan will start to rotate. If the manufacturer suggests so, you can even lubricate the fan to allow it to rotate smoother. If the problem persists, it’s best to call a technician.
It smells bad
If your unit has a filter that you haven’t replaced or cleaned in a while, chances are it will create a heavy, musty smell that will soon be spread into the air. The simplest way to prevent that is to remove the filter, give it a shake, spray it with some vinegar or hydrogen peroxide, and allow it to dry before reinstalling it. Use baking soda in the water tank to prevent mold and mildew in the future.
