You had chosen carefully to get a good dehumidifier and expected for a smooth running, but sometimes your dehumidifier did not work well and got some problems. These dehumidifier common mistakes may not cause from the manufacturers or product mistakes. This also depends on how you use a dehumidifier and its working condition such as the weather temperature. It is necessary to know some common dehumidifier problems so that you can avoid these problems or least you know how to fix them. The lists below are five common mistakes of dehumidifiers.
Most Common Dehumidifier Problems: It Does Not Turn On
If your dehumidifier doesn’t start, you need to check:
- The power source: make sure that the dehumidifier is plugged into a working outlet. You can try by plugging something else into the same outlet; if it works then you know you have the power for the dehumidifier.
- The power cord: if the other equipment can work well with that outlet except for your dehumidifier, you should check the power cord and replace it if necessary.
- The tank: when the tank is full, many dehumidifiers have a safety device which helps switch off to prevent any water damage to the unit. So you need to empty the tank if it is full. If the dehumidifier still does not work, you can remove or replace the switch.
- The humidistat: another reason that the dehumidifier cannot turn on may be the humidity level you set for the unit has been reached, so you have to adjust the humidistat to lower the humidity level. If there is something wrong with the humidistat, you can check it by using a simple volt-ohm meter. This device is also used to check the overflow switch. Set the meter to the RX1 scale and attach it to the humidistat, then you turn the knob as far as it will turn in both directions. If it stays at zero, the humidistat has a problem and must be replaced.
Dehumidifier Freezes Up
The next common dehumidifier problems are when it freezes up. Running a dehumidifier with iced up can damage the compressor. When the dehumidifier ices up, firstly you turn off the unit for a little bit and let everything thaw out.
Frosting can take 10 to 15 minutes. If frost or ice remains, your room temperature may be too low.
Thus, you need to do:
- Take a look at the room temperature: A dehumidifier will often frost up if room temperatures are colder than about 18°C. If your room temperature is too cold, you can raise the temperature slightly. Besides, you can try setting a small blower or heater at the unit so that it can get warmer air.
- Set the dehumidifier far enough from the wall: to ensure that the room air moves freely through the unit so that it can avoid freezing up.
- Check the fan: be sure that the fan is working. If the fan is faulty, it cannot blow air across the coils, and then the dehumidifier will freeze up.
- Clean the filter: if your dehumidifier has a filter, let follow the manufacture’s instruction to clean it.
- Check the dehumidifier: Finally, you plug the unit in and turn it on to see whether it freeze up again.
Dehumidifier Is Noisy
If your dehumidifier makes a strange noise, don’r worry! This is just one of the most common dehumidifier problems. In this case, you need to check some parts of the unit such as blower wheel, fan blade, fan motor. Usually, the noise is caused by loose and vibrating parts.
Look for loose screws or vibrating parts: Try turning these parts by hand. If it is loose, tighten it. In case it does not turn freely or damaged, replace the new one.
When the dehumidifier still makes noise, you can bring it to the repair shop.
The reservoir fills so fast. This happens because there is a lot of moisture in the air.
You can find the source of moisture near dehumidifier and control it. This may help reduce the filling process. This is not a big problem, but if you do not like emptying the tank frequently, there are drain hose attachment for most models.

Dehumidifier Smells Bad
The last common dehumidifier problems are their bad smell. If the dehumidifier smells bad, it’s time for you to clean it.
You should not use any types of chemicals because they can be harmful to the unit and yourself as well.
Instead, use vinegar and hydrogen peroxide to clean the reservoir, coils, and filter.
- Prepare spray bottles: one with white vinegar, another with hydrogen peroxide
- Clean the reservoir: firstly emptying the reservoir and mopping up any dirty areas. Then spray the inside of the reservoir with white vinegar and wait for about 10 minutes. Later rinse with clear water. Use a clean cloth to wipe it out. Continue with hydrogen peroxide in the same steps.
- Clean the coils: with the same process but allow the unit to dry in a warm place for at least 24 hours.
- Clean the filter: remove the filter and spray it with vinegar, also leave it for 10 minutes. Then rinse it and spray with hydrogen peroxide. Let it sit for 10 minutes, rinse it and wipe it with a clean cloth.
Remember empty the tank frequently and maintain cleaning, your dehumidifier will never smell bad. This also helps prevent mold and bacteria grow.
