Error codeF9
ApplianceRange
F9 is a pointer, not a diagnosis
In the Technical Manual for the Dacor ER30D, ER36D and ER48D ranges, F9 does not name a part. It names an area, the door lock, and a second, specific code is normally shown after it.
What to do when F9 shows
Watch the display for the code that follows F9 and write it down.
Check the simple things the manual lists first: the main power switch may be off, or the control panel may be locked.
Where to look next
F90 is the door latch entry: loose or defective latch cables, or a defective latch assembly.
F3 is a different general location, external faults.
