Error codeEF1
ApplianceDryer
What EF1 means
A blocked vent is the meaning the sheets give, for the current dryers behind sheet 137559700C (1302 edition) and sheet 137265000B (1202 edition).
Four possible conditions
Heavy restriction in the vent
The Exhaust Control Thermistor is faulty
The Inlet Control Thermistor is faulty
The electronic control board is defective
Owner steps
Stop starting new cycles while EF1 is displayed, and disconnect the dryer until someone finds the cause. Testing the thermistors and board is technician work.
Other EF codes
EF3 (max timeout timer) draws on the same exhaust and thermistor entries, while EF8 reports a stuck key.
Frigidaire dryer service for San Francisco
Starting a visit takes one call to (415) 319-6371. Say the dryer shows EF1, supply the model number and mention anything you tried, then see Frigidaire dryer repair.
Model compatibility: Frigidaire reuses codes across series and model years, so EF1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Vent blocked.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
