Why Does My Dehumidifier Ice Up? Find Out What Causes it and How to Fix it

Contents

Is your dehumidifier forming ice buildup and not functioning correctly? Keep reading to learn why your dehumidifier is icing up and the best portable air conditioners to help prevent this issue in the future.

Quick Summary

Ice buildup on dehumidifiers is a common issue, best avoided by regular maintenance and inspection. It can happen due to many different causes — from an unclean filter to cold temperatures, a buildup of frost can form on the unit. It is important to regularly check for foreign objects, debris, dust and any other blockages in the dehumidifier’s air vents and filter. Also, make sure the room temperature is neither too hot or too cold. If temperatures become too cold, the unit will become more prone to frosting up. If your dehumidifier is already showing signs of frost, you can reset the unit. Turn it off and unplug it, then let it sit for at least one hour before restarting it. To avoid this problem in the long-term, make sure to properly maintain and keep the dehumidifier dust- and debris-free.

What Causes My Dehumidifier to Ice Up?

Dehumidifiers are a great solution for controlling humidity levels in your home and keeping your air clean and healthy. But what happens when something goes wrong and your dehumidifier starts to ice up? It’s an issue that can cause your dehumidifier to become inefficient, or even break down. Fortunately, understanding why your dehumidifier is icing up is the first step in solving the problem.

What Causes My Dehumidifier to Ice Up?

The most common cause of your dehumidifier icing up is that it is not cooling the air enough. When the air is not cooled properly, the humidity in the air is higher than normal and this can cause the coils in the dehumidifier to freeze up. Other causes of your dehumidifier icing up can include the accumulation of dust and dirt on the coils, a blocked air filter, low refrigerant levels, a faulty fan motor, or an obstructed air intake.

How to Fix an Icing Up Dehumidifier

  • Clean or replace the air filter.
  • Check the refrigerant levels and refill, if necessary.
  • Clean the coils, if necessary.
  • Check and replace the fan motor, if necessary.
  • Clear the air intake if it’s blocked.
  • Invest in a more powerful portable air conditioner for your camper trailer.

  Solve the Mystery: Why Does My Dehumidifier Ice Up? Learn What Causes it and How to Fix it

My dehumidifier icing up can be a common issue. This issue can be caused by many factors, including low temperature in the room and low humidity levels in the air. Icing up can reduce the dehumidifier’s efficiency, so it’s important to identify and address the underlying cause.

If the dehumidifier is set to a temperature below 65 degrees or the room is naturally cold, the air may not be able to absorb adequate moisture. This can lead to ice buildup as the dehumidifier works to withdraw moisture from the air. If this is the case, I recommend raising the temperature to above 65 degrees to improve air circulation and keep the dehumidifier from icing up.

Besides temperature, low humidity levels can prevent the dehumidifier from removing enough moisture from the air. If the relative humidity is below 40%, the dehumidifier won’t be able to remove sufficient moisture. In this situation, I recommend turning the dehumidifier’s humidity control to a higher setting (although this will reduce the device’s energy efficiency).

Along with these causes, I suggest checking the air filters of your dehumidifier, as they may be clogged or dirty. If they are, they won’t be able to remove enough moisture, resulting in ice buildup. To solve this, I recommend that you clean or replace the air filters on a regular basis.

Frequently Asked Questions

How do I stop my dehumidifier from icing up?

To stop a dehumidifier from icing up, check the room temperature and make sure there is at least one foot of clearance around the dehumidifier with good airflow. Clean the coils, or have a professional do it, and replace the filter if it is full. This will help keep the dehumidifier from icing up.

Why does my dehumidifier keep icing up?

Low room temperature, a faulty humidity sensor, or inadequate airflow can all cause a dehumidifier to icing up. To fix this issue, you should try moving the dehumidifier to a warmer room, replacing the humidity sensor, changing the filters, or replacing the blower fan. Taking the necessary steps to fix the issue will help ensure that your dehumidifier does not keep icing up.

Why does my Whirlpool dehumidifier freeze up?

The answer to why your Whirlpool dehumidifier is freezing up is likely due to one of three things: a low room temperature, an issue with the humidity sensor, or airflow issues like a broken blower fan or dirty filters. You should fix the culprit by moving the dehumidifier to a warmer room, replacing the humidity sensor, replacing the blower fan, or changing the filters. This should help resolve your freezing issue.

Why is my dehumidifier frosting up?

The moisture in the air may be causing your dehumidifier to freeze up. This commonly occurs when the room temperature is too cold and the water condenses and freezes on the cold coils. Another possible cause is poor airflow which prevents the water from draining quickly enough. To avoid frosting up, keep the room temperature at a comfortable level and ensure proper airflow for the dehumidifier.

How do you clean the coils on a Whirlpool dehumidifier?

To clean the coils on a Whirlpool dehumidifier, vacuum the top layer of dust and grime, or scrape it off with your hand. Use a soft-bristled brush, cloth, or spray detergent or a mix of vinegar and water to clean the coils. Rinse away any residue and make sure they dry before using the dehumidifier again.

Why is my Frigidaire dehumidifier icing up?

The likely cause of a Frigidaire dehumidifier icing up is that the room it is in is too cold. This causes the water to freeze on the coils instead of draining away. Poor airflow can also affect the ability of the water to drain quickly enough off the coils, leading to icing.

Why do the coils on my dehumidifier freeze up?

The coils on your dehumidifier may freeze up if the humidistat is not reading the humidity correctly. This causes the compressor to stay on, which may cause the electrical contacts to become welded shut. All of these occurrences can result in the coils freezing up.

Can a dehumidifier freeze up?

Answer: Yes, a dehumidifier can freeze up. The room temperature must stay above 41°F (5°C) otherwise the dehumidifier will freeze up due to faulty components, a dirty air filter, or bad airflow. Poor maintenance and the wrong environment are the most common causes of a frozen dehumidifier.

What is the best portable air conditioner for a campervan?

Can you use a portable AC unit for camping?

Yes, you can use a portable AC unit for camping. There are two types available – one that uses electricity and one that is battery-powered. If a campsite has an electric hookup, an electric powered AC unit is the most reliable and efficient option. However, battery-powered units are also available for those camping areas without electric hookups.

Final Thoughts

Humidifiers are essential appliances used to add moisture back into the air, and when they start to ice up it can be quite alarming. It’s important to understand the cause of the ice buildup and to address the root cause quickly and effectively. In some cases, the humidity level is simply set too high, while in others there may be a failure of the automatic shut off. Either way, it’s important to address the issue promptly, as continued icing can prevent your dehumidifier from functioning properly. Fortunately, troubleshooting the issue is simple and can be completed using these steps. With proper care, your dehumidifier will be functioning properly for years to come.
