Universal Failure & Error Codes

F 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 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 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 4 = Meat Probe Failure. Check for proper resistance on probe. If okay, replace the meat probe jack.

E1 = Meat probe shorted.

F 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 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 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.
