Frigidaire Dehumidifier: not running
What is this symptom?
Is your Frigidaire dehumidifier not running? If it fails to power on with no fan or lights, you may be facing a common issue. Potential causes include a faulty water bucket switch, incorrect humidity settings, or a power supply problem. Follow our guide to troubleshoot and restore your dehumidifier's functionality.
Important Tips for Frigidaire Models
- Bucket switch failures and humidistat issues are common fault points preventing the dehumidifier from starting.
Possible Causes
Faulty or full water bucket switch
How to Identify: Unit does not start even when bucket is empty; test switch for continuity with multimeter.
Part: Bucket float switch
Incorrect or low humidity setting
How to Identify: Unit shows settings that may prevent starting; humidity set above desired level.
Part: Humidistat/control panel
Dirty or clogged air filter restricting airflow
How to Identify: Visible dust buildup on filter; cleaning restores normal operation.
Part: Air filter
Faulty humidistat or humidity sensor
How to Identify: Humidity sensor does not detect or signal desired humidity change; no running even under high humidity.
Part: Humidistat/humidity sensor
Power supply or outlet issue
How to Identify: No power to unit; another appliance works in same outlet when tested.
Part: Power cord/outlet
Internal control board failure
How to Identify: Humidistat contacts close but unit still won’t start; board may be defective.
Part: Control board
Compressor or motor failure
How to Identify: Unusual noises or no component activity when power applied; requires advanced diagnosis.
Part: Compressor/fan motor
DIY Solutions
Check and reset bucket switch
- Unplug the dehumidifier and remove the bucket.
- Locate the float switch and test continuity with a multimeter.
- If faulty, remove and replace the bucket switch.

- Typical part-only price
- $20 - $100
- DIY difficulty
- Medium
- Estimated time
- 20-60 mins
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.

User Suggested Solutions
-
Check the power supply by plugging the dehumidifier into a different outlet or checking the circuit breaker. Ensure the unit is properly plugged in.
-
Test the humidistat by setting the dehumidifier to a lower humidity level. If it does not turn on, the humidistat may need replacement.
