UNIVERSAL FAILURE & ERROR CODES
F F F F F 1 1 1 1 1 =
Electronics Subsystem Failure. Replace the electronic control board.
E0 = EEPROM communication error.
E1 = EEPROM checksum error.
E2 = A/D converter error (is there an error bit in the microprocessor?; does this mean
lost a voltage rail?)
E3 = Configuration jumper (cavity size or gas/electric) does not match setting defined
in EEPROM (this was designed to notify the installer that the jumpers were not
reconnected properly).
E5 = Calibration shifted.
E9 = Stack overflow.
F F F F F 2 2 2 2 2 = Keypad Subsystem Failure. Replace the keypad if properly connected and this F code
is displayed.
E0 = Shorted keypad or keypad stuck.
E1 = Keypad or keytail not connected.
E4 = Keypads unsettled (applies to capacitive glass when a constant reading cannot
be taken).
E5 = Cancel key low or open.
F F F F F 3 3 3 3 3 =
Cavity Temperature Sensor Failure. Check for welded relays. If okay, replace the tem-
perature sensor.
E0 = Sensor open.
E1 = Sensor shorted.
E2 = Non self-clean over-temperature (usually 550˚F).
E3 = Self-clean over-temperature (usually 900˚F).
F F F F F 4 4 4 4 4 = Meat Probe Failure. Check for proper resistance on probe. If okay, replace the meat
probe jack.
E1 = Meat probe shorted.
F F F F F 5 5 5 5 5 = Latch Subsystem Failure. Check for proper latch movement, switch actuation, and
clearance between the 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.
E3 = Loss of ground or L1 to N is reversed. Check to make sure that the voltage from
L1 to ground is 120-volts AC.
E5 = Self-clean temperature set point is not reached within the required time range
(usually 30 - 45 minutes).
E7 = Latch will not unlock.
F F F F F 6 6 6 6 6 = Electronics Over-Temperature. Check the blower and ventilation system.
E0 = Over-temperature with blower on high speed.
E1 = Over-temperature with blower on low speed.
E2 = Over-temperature with blower off.
F F F F F 7 7 7 7 7 =
Digital Switch Signal (i.e. 5 vdc @ 1kHz) Failure. Check for shorted door or latch switch
wiring to chassis ground.
E0 = Signal line shorted to ground.
