F-CODE GUIDELINES
F0 = If the most recent F-code is recalled via user input, F0 indicates no failure has occurred.
F1 = Electronics Subsystem Failure.
Replace electronic control board.
E0 = EEPROM communication error.
E1 = EEPROM checksum error.
E2 = A/D converter error (is there an error bit in the micro?; does this mean lost a voltage
rail?).
E5 = Calibration shifted.
E9 = Stack overflow.
F2 = Keypad Subsystem Failure. Replace keypad if properly connected and this F-code is
displayed.
E0 = Shorted key / key stuck.
E1 = Keypad / keytail not connected.
E5 = Cancel key low or open.
F3 = Cavity Temperature Sensor Failure.
Check for welded relays; if OK then replace temperature sensor.
E0 = Sensor open.
E1 = Sensor shorted.
E2 = Non-self-clean over temperature (usually 550˚F).
E3 = Self-clean over temperature (usually 900˚F).
F5 = Latch Subsystem Failure.
Check for proper latch movement; check for proper switch actuation; check for proper
clearance between latch and door.
E0 = Latch switch does not agree with door switch (i.e. Iatch in locked position with door
open).
E1 = Latch will not lock.
E5 = Self-clean temperature set point not reached within required time range (usually
30 to 45 minutes).
E7 = Latch will not unlock.
NOTE: Never lock the door in association with an F-code. The door should only lock at high
temperatures (usually above 550˚F) or while in Self Clean. The door should unlock immediately
when the cavity falls below the unsafe temperature.
