Whirlpool 4322452 manual Code Guidelines, F0 =

		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.
