Error codeF90

Reading F90
F90 belongs to the door latch. Dacor’s Technical Manual lists it among the control panel error codes for the ER30D, ER36D and ER48D, with two possible explanations:
cables running to the door latch are loose or defective;
the door latch assembly is defective.
Remedies the manual prescribes
Cables: the connections are tightened, or the cable itself is repaired.
Latch assembly: a replacement goes in.
A technician carries out both remedies. All the manual asks of an owner is a glance at two things beforehand: that the main power switch is on and that the control panel is not locked.
Nearby entries
F9 is the general door lock location that a specific code such as F90 follows.
F32 is a separate cable code, tied to the control panel data link.
Repair for a Dacor range in the Bay Area
When F90 appears on a Dacor range in San Francisco, start at Dacor range repair and call (415) 687-5926. It helps to state the code, the model number and whichever checks you have already done.
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
F90 means the door latch cables are loose or defective, or the door latch assembly is defective.
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.
