Error codeF1
ApplianceRange
F1 is a location, not a diagnosis
Type: general fault location.
Location: internal, meaning the controller board in the control panel.
Series: the ER30D, ER36D and ER48D, an older range line.
Read the display twice
A specific code normally appears after F1, and that one names the real problem, so write both down. F2, F3 and F9 (door lock) are the other general codes in the same list.
F20 is a loose or defective data cable, or a control panel circuit board.
Dacor range service in San Francisco
Dacor range owners in San Francisco and around the Bay Area can ring (415) 687-5926 and read about Dacor range repair. Give both codes from the display plus the model number.
Model compatibility: Dacor 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.
