Error codeF5
ApplianceRange
Quick answer
F5 means the watchdog circuit was active when it should be disabled, on older Frigidaire electronic oven controls.
Model compatibility: Frigidaire reuses codes across series and model years, so F5 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
Watchdog circuit active when it should be disabled; EOC relay failed operation test after Bake, Broil or Clean selection.
F5 comes from an older series of Frigidaire electronic oven controls (EOC). It means the watchdog circuit was active when it should be disabled.
When the control raises it
After you select Bake, Broil or Clean, the microprocessor tests that the EOC relay operates. F5 appears when the relay fails that test.
What a technician checks
The fault sheet tells a technician to look for a shorted keypad, or pushbuttons binding in the glass and stuck. If neither is the cause, the EOC is replaced.

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.
