Error codeF3
ApplianceRange
Quick answer
F3 is a general external fault location on legacy Dacor ER ranges, usually followed by a specific code.
Model compatibility: Dacor reuses codes across series and model years, so F3 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
General fault location: external; usually followed by a specific code.
F3 tells you where to look, not what failed. In the Dacor range Technical Manual it is a general fault location: external. A specific code usually follows it on the display, and that second code carries the real detail. The list is for the legacy ER30D, ER36D and ER48D ranges.
What to do
Write down the code that appears after F3. Check the basics the manual names first: a main power switch that has been turned off, or a locked control panel.
Codes that may follow
F30: shorted temperature sensor or shorted sensor wiring.
F31: open temperature sensor or open sensor wiring.
F90: door latch cables loose or defective, or a defective door latch assembly.
