Why Is your Dehumidifier Icing Up?
A dehumidifier works by pulling moisture out of the air and condensing it so that it can be removed. The dehumidifier absorbs this water vapor, which creates a slight amount of heat as a byproduct of the absorption process.
This heat starts to warm up the inner components of the dehumidifier, but if there isn’t a reliable method of removing the built-up heat, it can lead to dehumidifier freezing or dehumidifier iced up problems.
When this happens, you need to know how to fix dehumidifier freezing before it becomes a bigger problem.
Common Reasons That Causes Dehumidifier Freezing Up
1. A Lack of Drainage or Venting Option
Many dehumidifiers are designed to be vented to the exterior, but if your dehumidifier doesn’t have this option, it can’t get rid of moisture.
If you dehumidify in a room that lacks sufficient ventilation, then your dehumidifier freezing will become much more likely.
If you dehumidify in a basement or other space that doesn’t have proper ventilation, then your dehumidifier can run into dehumidifier freezing problems without being able to release the built-up heat.
This is why it’s important to properly vent dehumidifiers even if they are placed where there isn’t a dehumidifier draining option.
2. Not enough airflow is present to remove the built-up heat
As the dehumidifier is running, it’s going to pull a small amount of moisture out of the air and then use that water vapor in its cooling process.
If there isn’t a way for this water vapor to escape, then the dehumidifier will start to accumulate a small amount of heat as a result of this process.
If there isn’t a way for the dehumidifier to release that built-up heat, then dehumidifier freezing is likely to occur. To avoid dehumidifier iced up problems, make sure that your dehumidifier has plenty of room to breathe.
3. The dehumidifier is not set up properly
The dehumidifier might be dehumidifying just fine, but if it’s not dehumidifying at the right rate or in the right way, then dehumidifier freezing will become much more likely.
This is why it’s important to dehumidify the right area and dehumidify only as much as needed. If you have a dehumidifier that is set up improperly, then dehumidifier freezing will become more likely if you don’t do anything about it.
4. The dehumidifier’s mode is set incorrectly
The dehumidifier might dehumidify efficiently, but if it’s dehumidifying in a mode that isn’t suited for your needs or the humidity level in the room, then dehumidifier freezing could become a much more likely outcome.
If you want to avoid dehumidifier iced up problems, then dehumidify in an efficient way and dehumidify at the right humidity.
5. The dehumidifier’s filter is not clean
Dehumidifiers need to have filters that are working well, or dehumidifier iced up problems may become more likely as time goes on.
If your dehumidifier’s filter is dirty, then dehumidifier freezing will become more likely because the dehumidifier won’t function properly.
Clean dehumidifier filters are something that you should pay attention to if dehumidifier iced up problems become a noticeable issue.
6. Running at Low temperature for Long Periods
Running dehumidifiers at a low temperature for long periods of time increases dehumidifier freezing by making dehumidification less efficient.
If you want to avoid dehumidifier iced up problems, then you should dehumidify at the proper temperature and turn your dehumidifier off when it’s going to low temperature.
7. The humidity sensor isn’t working
Another reason could be faulty humidistat, because if the humidity sensor isn’t working, then it won’t be able to detect when the proper humidity has been reached.
If this is happening, then you will avoid dehumidifier iced up problems by making sure that the sensor is properly working every time that you use your dehumidifiers.
8. The dehumidifier condensation drain is not connected
If your dehumidifier doesn’t have a condensation drain, then it won’t release any moisture at all. If you run this type of dehumidifier for long periods of time in an area that’s relatively warm, then it will start to build up heat, and dehumidifier freezing will become much more likely. Avoid this by connecting a condensation drain to your dehumidifier before you turn it on.
9. Dehumidifier accumulates water in the tank or bucket
If your dehumidifier’s tank fills up, then it won’t have anywhere to store the actual water that has been pulled from the air.
If this is what’s happening, then dehumidifier freezing will become more likely because your dehumidifier won’t be able to pull in any moisture until the tank has been emptied.
Make sure you empty the tank every day so that dehumidifier iced up problems don’t become an issue.
10. Not using the right dehumidifier for the job
If you’re using an oversized dehumidifier, then running it at low temperatures will lead to faster dehumidifier iced up problems.
The same can be said about undersized dehumidifiers – if you run them for long periods of time without enough humidity in the air, then they will become less efficient and dehumidifier freezing will become more likely. Make sure you use the right-sized dehumidifier in the right setting to avoid dehumidifier iced up problems.
Since we already know the most common reasons that cause the dehumidifier freezing problem, let’s find out its solutions.
How To Fix A Frozen Dehumidifier
1. Turn the dehumidifier off for a couple of days
If your dehumidifier has frozen up, however, you should leave it turned off for a few days. Let it thaw out, and make sure that your dehumidifier is in an area where the temperature won’t drop below freezing again anytime soon.
If this doesn’t work, then you can try these solutions below:
2. Make certain that the condensation drain is working properly
It’s possible that the condensation drain is clogged up or broken. You should make sure that this isn’t what’s causing your dehumidifier to freeze up because if it is, then you won’t be able to solve your problem until you get a replacement draining system fixed in place.
3. Try restarting the dehumidifier
If your dehumidifier is frozen up, then you should restart it. Let it run for a few minutes or hours before you turn it off, and this will give it the opportunity to thaw itself out again. This is a good solution if leaving your dehumidifier turned on overnight isn’t an option.
4. Keep the dehumidifier in a warmer room
If you have your dehumidifier stored in a cold room, then it will be more likely to freeze up. You can avoid this by moving it to a warmer area where the temperature won’t drop below freezing again anytime soon.
Make sure that you don’t turn on your frozen dehumidifier while it’s in a warm room, or you’ll have to deal with dehumidifier iced up problems all over again.
5. Empty the water tank completely
The tank doesn’t hold a lot of water, so if your dehumidifier fills up and then freezes before you can empty it, then you may be headed for dehumidifier iced up problems.
Make sure that you empty the tank every single time that it fills up if you want to avoid them altogether.
6. Drain your dehumidifier before storing it away
It’s not always necessary to drain your water tank if you’re going to turn your dehumidifier off for a long period of time, but if you do this before storing it away, then you’ll reduce the chances that your dehumidifier will freeze up while it’s turned off. It’s never a bad idea to drain your water tank completely on a regular basis anyway.
These solutions will help you to unfreeze your dehumidifier.
It’s easy to unfreeze your dehumidifier if you know how, but it can be just as easy to avoid problems in the first place by following these tips. If you’re not sure which solution is best for your specific frozen dehumidifier problem, then simply try them all out one by one until you find the one that works for you.
