Frigidaire Home Comfort Dehumidifier Not Collecting Water: How to Fix It Yourself
When a Frigidaire dehumidifier runs but does not collect water, the most common reasons are dirty coils, a room temperature that is too cold, or a full bucket sensor that is stuck. Cleaning the coils and filter restores performance in the majority of cases. Check the room temperature first — dehumidifiers struggle below 60 degrees.
⚠️ Safety First
- Unplug the dehumidifier before cleaning or inspecting internal parts.
- Do not operate the dehumidifier in temperatures below 60 degrees Fahrenheit — the coils will frost up.
- Empty the water bucket before moving the unit to avoid spills.

Step-by-Step Repair
- 1
Check the room temperature
Dehumidifiers work by cooling air until moisture condenses out of it. If the room is below 60 degrees Fahrenheit, the coils will frost over instead of collecting water. Check the room temperature. If it is cold, warm the room up before running the dehumidifier, or look for a model rated for low-temperature operation.

Clean or replace the air filter
Pull out the air filter — it is usually behind or under a front grille panel. If it is clogged with dust, the unit cannot pull in enough air to dehumidify effectively. Wash the filter with warm soapy water, let it dry, and put it back. Clean this filter every two weeks for best performance.
- 3
Clean the condenser and evaporator coils
Unplug the unit and remove the back panel if possible. You will see two sets of coils. Use a coil brush and vacuum to remove dust and debris from both sets. Dirty coils dramatically reduce the dehumidifier's ability to condense water. This is the most impactful maintenance you can do.
- 4
Check the bucket and float switch
Remove the water bucket and look at the float switch — a small arm or float that rises with the water level. If it is stuck in the up position, the dehumidifier thinks the bucket is full and will not collect water even though the bucket is empty. Move the float up and down by hand a few times to free it. Clean any mineral deposits off the float mechanism.
- 5
Verify the humidity settings and test
Set the desired humidity to the lowest setting (usually 35%). This forces the compressor to run continuously. Let the unit run for an hour. If it starts collecting water, the previous humidity setting may have been too close to the actual room humidity. If it still does not collect water and the compressor is running, there may be a refrigerant leak.
If That Didn't Work
- Low refrigerant from a sealed system leak
- Faulty compressor
- Defective humidity sensor giving incorrect readings
- Room humidity already at or below the set target
When to Call a Professional
If cleaning does not restore water collection and the compressor is running, the sealed refrigerant system may be leaking. This repair requires a certified HVAC technician and costs $100–$250. If your dehumidifier is more than 5 years old, replacing it is usually more economical than a refrigerant repair.
