Frigidaire Dehumidifier: not condensing
What is this symptom?
If your Frigidaire dehumidifier is running but not condensing moisture, it may be due to low temperatures, a clogged filter, or incorrect settings. Check the unit's airflow and ensure it’s set to the right humidity level to effectively reduce moisture in the air.
Important Tips for Frigidaire Models
- Frigidaire specifically recommends checking RH% settings and airflow as primary troubleshooting steps for no water collection.
Possible Causes
Low ambient temperature reducing condensation effectiveness
How to Identify: Occurs in cooler environments; coils may frost up and unit stops removing moisture. Humidity stays high.
Part: Cooling coils / refrigeration cycle
Clogged or dirty air filter reducing airflow across coils
How to Identify: Visible dust/debris on filter; weak airflow; minimal condensation.
Part: Air filter
Improper humidity setting on the control panel
How to Identify: Setpoint too high (unit thinks desired humidity already met; dehumidifier runs but collects little water.
Part: Control settings / humidistat
Full water bucket or stuck float switch
How to Identify: Bucket is full or float is stuck triggering shut-off; unit runs without collecting water.
Part: Float switch / water bucket
Faulty compressor or refrigerant issue
How to Identify: Compressor does not start or audible, coils fail to cool; unit runs fan but no condensing.
Part: Compressor / refrigerant system
Faulty control board or humidity sensor
How to Identify: Settings changes not affecting operation; no compressor activation despite high humidity.
Part: Control board / humidity sensor
DIY Solutions
Clean or replace air filter
- Unplug the dehumidifier.
- Remove the air filter.
- Clean with a soft brush or vacuum; wash and dry if washable.
- Reinstall the filter and power on the unit.
Adjust humidity setpoint
- Check the current humidity setting on control panel.
- Lower target RH% to a more aggressive moisture removal level (e.g., 40%-50%).
- Allow unit to run for several hours.
- Observe for water collection.
Move unit to warmer location
- Determine room temperature with a thermometer.
- Relocate unit to an area that stays above about 65°F.
- Ensure airflow around unit is unobstructed.
- Run unit and check water collection.
Check water bucket and float switch
- Ensure water bucket is empty.
- Check float moves freely and isn’t stuck.
- Reinsert bucket ensuring it sits correctly.
- Run unit; verify operation resumes.

Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Humidity Sensor
Measures relative humidity so the appliance can regulate drying or moisture removal.
Compressor
Compresses refrigerant within the sealed cooling system and requires specialized service equipment.
HVAC Control Board
Controls fan, compressor, sensor, and communication functions in the HVAC unit.

User Suggested Solutions
-
Clean or replace the air filter. Turn off the dehumidifier, remove the filter, and clean it with warm soapy water. Allow it to dry completely before reinstalling.
-
Check for refrigerant leaks. If low refrigerant is suspected, contact a professional technician to inspect and recharge the refrigerant.
-
Test and replace faulty sensors. Use a multimeter to check sensor functionality. If faulty, replace with a compatible part.
