Meaning of F1
Five other codes sit with F1 under one heading in the dehumidifier error code guide: AS, ES, F2, L1 and F5. The heading states that a temperature or humidity sensor has failed.
Steps listed
Book a technician visit.
A unit installed in the past 30 days returns to the installer.
Homes in San Francisco and the rest of the Bay Area can reach us about an F1 on (415) 319-6371, or through Frigidaire dehumidifier repair. Say which model you have and when the code first showed.
Model compatibility: Frigidaire reuses codes across series and model years, so F1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
