Error codeF12
ApplianceRange
Ranges and wall ovens with an electronic oven control (EOC) show F12 for a bad micro identification. Owner support words the same fault as “Micro Identification”.
Try this first
Take power away from the oven.
Wait out thirty seconds.
Restore power and watch the display at start-up.
If F12 comes straight back
The fault code sheet answers a start-up repeat with a replacement control, carried out by a technician.
A fresh installation
For an oven installed in the last 30 days, the owner support guide says to go back to whoever installed it. Past that window the next step is arranging service.
When F12 will not clear, a booking for a San Francisco kitchen starts at (415) 319-6371. Have the code, the oven’s model number and the outcome of the reset to hand. The Frigidaire range repair page lists the rest.
Model compatibility: Frigidaire reuses codes across series and model years, so F12 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
F12 is a bad micro identification fault on the oven's electronic control.
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.
