Full Answer

If a Frigidaire dehumidifier doesn’t start, first check to confirm that the device is switched on and that the power cord is connected to a working electrical outlet. Reset tripped circuit breakers and replace any blown fuses. Remove and test the humidistat for continuity using an ohmmeter and replace if defective. If the problem persists, examine the relay, compressor motor and overload switch, and replace any of them if defective.

If the dehumidifier overflows or leaks, examine the float switch. The float switch prevents the unit from spilling water that has been drawn from the air. A faulty float switch is irreparable and must be replaced. Inspect the drain tube to see whether it is broken or blocked, and replace or clean it as needed. Additionally, straighten any bends or kinks in the drain hose.

If a Frigidaire dehumidifier is not working efficiently, clean the condenser and evaporator coils if dirty.

Check whether the fan is blowing air across the coils as required. If not, use an ohmmeter to test the fan motor for continuity and replace the fan if necessary. If the above repair methods do not solve the problem, contact a Frigidaire professional for assistance.
