Error codeF9
ApplianceRange
Quick answer
F9 is a general door lock fault location on legacy Dacor ER ranges, usually followed by a specific code.
Model compatibility: Dacor reuses codes across series and model years, so F9 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: door lock; usually followed by a specific code.
F9 on a Dacor range points to the door lock area. The Technical Manual calls it a general fault location: door lock. A specific code usually follows it, which is where the detail is. The entry applies to the legacy ER30D, ER36D and ER48D ranges.
What to do
Read the display for the code after F9 and keep a note of it. The manual’s first advice is to look for obvious problems such as a main power switch that is off or a locked control panel.
Related codes
F90: door latch cables loose or defective, or a defective door latch assembly.
If F9 stays on a Dacor range in Los Angeles, call (310) 742-1907 for Dacor range repair. Give the technician F9, the specific code after it and the model number.
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.
