‘Why does my basement dehumidifier ice up?’ – Unlock the secrets behind the common issue of basement dehumidifiers icing up with our comprehensive guide. Icing can be a result of several mistakes you make when handling and maintaining the unit. Understanding why your dehumidifier forms ice on its coils is crucial to maintaining a dry and healthy basement environment. In this exploration, we’ll uncover the root causes, offering insights into how temperature settings, dirty filters, and other factors contribute to the freezing phenomenon. So, stay ahead of potential damage and ensure your dehumidifier operates at its best by unraveling the mysteries behind the ice buildup. Without further introductory utterances, let’s start discussing the problem!

Why does My Basement Dehumidifier Ice Up?

Your basement dehumidifier can ice up because of low-temperature settings, dirty coils or filters, etc. Let’s discuss each cause in detail. 

  1. Low-Temperature Settings: If the dehumidifier is set to operate in colder temperatures, it may lead to the freezing of the coils, causing ice buildup.
  2. Inadequate Room Temperature: Operating the dehumidifier in an excessively cold basement can result in the coils dropping below the dew point, leading to condensation and ice formation.
  3. Dirty or Blocked Coils: Accumulated dirt, dust, or debris on the coils can reduce heat exchange efficiency; as a result, the coils become colder and promote ice formation.
  4. Inadequate Airflow: Insufficient airflow prevents water from draining off the coils rapidly, potentially obstructing your dehumidifier. If this occurs, it could be due to an obstruction. 
  5. Dirty Filters: Dirty filters can result in restricted airflow, causing the dehumidifier to freeze up. A clogged air filter, filled with dirt and dust, can impede airflow, resulting in inadequate air circulation. Consequently, the coils can freeze due to the insufficient movement of air.
  6. Broken Fan: Another cause is a malfunctioning fan. Regularly inspecting the operational elements of your dehumidifier is crucial to ensure everything functions correctly. If the fan malfunctions, it can disrupt airflow, potentially causing permanent damage to the appliance.
  7. Refrigerant Issues: Low refrigerant levels or malfunctions in the refrigeration system can hinder the proper functioning of the dehumidifier, leading to icing.
  8. High Humidity Levels: In certain conditions, high humidity levels can overwhelm the dehumidifier’s capacity, causing the coils to become excessively cold and freeze too.
  9. Faulty Defrost Control: If the defrost control mechanism is malfunctioning, it may not effectively prevent ice buildup on the coils.

How to Fix When your Basement Dehumidifier Ices Up?

When your basement dehumidifier ices up, you will need a systematic approach to identify the root cause and fix it. The following guide will surely be helpful, so keep reading. 

  1. Turn Off and Unplug: First of all, power off the dehumidifier and unplug it from the electrical outlet to ensure safety during troubleshooting.
  2. Allow Thawing: Then, let the iced coils thaw naturally. Removing the ice buildup is essential for the dehumidifier to function optimally.
  3. Check Temperature Settings: Adjust the temperature settings on the dehumidifier to ensure they are appropriate for the ambient conditions in your basement.
  4. Inspect Airflow: Examine the unit for any obstructions hindering airflow. Ensure there’s ample space around the dehumidifier for proper ventilation.
  5. Clean or Replace Air Filter: If the air filter is dirty or clogged, clean it or replace it according to the manufacturer’s instructions. Then, there will be better airflow.
  6. Examine Refrigerant Levels: If you suspect refrigerant issues, consult a professional technician to inspect and replenish refrigerant levels.
  7. Check for Mechanical Issues: Inspect the fan and other mechanical components for any malfunctions. Sometimes, you will have to replace such malfunctioning components, especially if the dehumidifier is an aged one.
  8. Monitor Humidity Levels: Keep an eye on the humidity levels in the basement. Adjust the settings on the dehumidifier accordingly to prevent over-drying or excessive moisture.
  9. Regular Maintenance: It is highly important to establish a routine for regular maintenance, including cleaning coils, checking filters, and ensuring proper functioning to prevent future icing issues.

If the dehumidifier still ices up, it’s advisable to consult the dehumidifier’s user manual or seek professional assistance for a thorough assessment and repair.

How Do I Clean the Coils On My Dehumidifier

How Do I Clean the Coils On My Dehumidifier?

Cleaning the coils on your dehumidifier is essential, especially if there is ice buildup. So, let’s see what steps you need to follow. 

  1. Turn Off and Unplug: First, ensure the dehumidifier is powered off and unplugged to guarantee safety during cleaning. Wait some time until the ice melts. 
  2. Access the Coils: Next, remove the front grille or access panel to reach the coils. Refer to your dehumidifier’s manual for specific instructions.
  3. Use a Soft Brush or Vacuum: Gently wipe or vacuum the coils to remove any ice residue. Be cautious to avoid bending or damaging the fragile fins.
  4. Damp Cloth or Sponge: If the coils are particularly dirty, use a damp cloth or sponge to wipe away stubborn residues. Avoid excessive moisture to prevent damage.
  5. Air Dry: Allow the coils to air dry completely before reassembling the dehumidifier.

Remember to consult your dehumidifier’s manual for specific guidelines and safety precautions during the cleaning process.
