Error codeF90
ApplianceRange
Quick answer
F90 on a legacy Dacor ER range means loose or defective door latch cables, or a defective door latch assembly.
Model compatibility: Dacor reuses codes across series and model years, so F90 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
Door latch cables loose or defective, or defective door latch assembly.
F90 on a Dacor range is tied to the door latch. The Technical Manual lists two causes: the cables to the door latch are loose or defective, or the door latch assembly is defective. The list covers the legacy ER30D, ER36D and ER48D ranges.
Manual remedies
For the cables, tighten the connections or repair the cable. For the latch assembly, replace it. This is technician work. Owners can check the main power switch and the control panel lock first.
