Quick answer
F1-A, F1-C, F9-1, F9-2 and F9-3 are all listed by JennAir under the oven door latch, lock switch and wiring.
Model compatibility: JennAir reuses codes across series and model years, so F1-A / F1-C / F9-1 / F9-2 / F9-3 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
A possible problem with the Oven Door Latch, the Door Lock Switch, or the associated wiring.
On the range page, JennAir gives five codes one explanation: F1-A, F1-C, F9-1, F9-2 and F9-3. All concern the oven door lock, and wall ovens are not part of this group.
Named for every code
The oven door latch
The door lock switch
The wiring that belongs to them
JennAir does not say how the five numbers differ.
A note on terms
Other door entries from JennAir use the phrase “Door Switch”. This one uses “Door Lock Switch”. As general background, that switch is the contact that reports whether the lock is engaged.
Steps for owners
Switch the range off at the breaker for sixty seconds.
Switch the power back on.
Give the range a minute and see if the code comes again.
Run the oven and check that it works.
No waiting period comes before the reset; the first instruction is to take the power away for a minute.
Results
A clean display with a working oven means JennAir expects nothing more. If any of the five codes returns, the latch, the lock switch and the wiring are all still possible, and the source offers no further steps. That means service.
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.
