NOTE:
Control display will flash “LOCK DOOR”
if the door switch is in the “C” to “NC” position
(door open).
●
The words “LOCK DOOR” will flash on and
off in the display while the lock motor is in
motion, When the door is locked, the words
“LOCKED DOOR” remain illuminated in the
display.
●
CAM - The cam on the motor performs two
functions:
1. Positions the lock hokk in the door to
prevent opening during clean operation.
2. Operates the lock switches which tell the
control if the door is unlocked or locked
and ready for Clean operation.
FAILURE
CODE
MEANING
CORRECTION
-F0- Shorted OFF key (Mem-
brane) or GT Error
Perform glass touch board key panel test.
-F2- Over temperature
1. Inside oven cavity as measured
by sensor over 650°F unlatched or
915°F latched
-F3- Open oven sensor (under
950 ohms)
-F4- Shorted oven sensor (over
2900 ohms)
-F7- Shorted matrix or START
key
-F8- EEPROM data shift failure
-F9- Cooling fan stalls while above
650°F; open thermal switch in
yellow lead
-FC- Loss of latch motor safety
circuit
- Welded relay contacts
- Cooling fan stalled or blocked
- Airflow to rear of unit
- High resistance in oven sensor leads/connectors
(especially at sensor in rear)
- Disconnect power. Disconnect sensor harness from
control. Measure sensor resistance (white leads) to
be ~ 1080 ohms at room temperature with 2 ohms
per degrees change.
- Look for damaged harness terminals is not a bad
sensor.
Replace control.
Cooling fan or airflow to control area.
If repeated, replace control.
Determine if problem is with keyt panel or control by
disconnecting ribbon cable and measuring flat cable using
pinout chart. Allow up to 1000 ohms when pressing a key.
- Disconmect power Disconnect sensor harness from
control. Measure sensor resistance (white leads) to
be ~1080 ohms at room temperature with 2 ohms per
degree change.
- Separate sensor from harness to determine fault.
ERC FAILURE CODES
The oven may stop operating but not give an F code on the display inmediately.
F codes are stored in nonvolatile EEPROM memory until the same fault occurs
twice consecutively. F codes can be recalled by pressing together TIMER, CLOCK
and 9. While F codes are desplayed, pressing 8 and 6 together will clear them. A
fault must exist continuously for 5 minutes before an F code is recorded (F2 and
F8 are Sooner).
MOTORIZED DOOR LOCK
The motorized door lock assembly is located above the oven. The assembly
consists of a lock motor cam and switch assembly, lock hook and mounting
plate.
MOTORIZED DOOR LOCK OPERATION
The lock motor is energized when the control is set for Clean and Clean Time
is selected. The K4 Relay contacts will close and complete the circuit that
supplies the voltage to the lock motor.

Motorized Door Lock Operation
:
NOTE:
To enable proper operation of the door lock, ensure that the door jamb switch
is in “common” to “normally closed” (door closed). This enables power to be delivered
when the door lock closes.
NOTE:
Display of Control will flash “
LOCK
” if the door switch is in the “
C
” (common)
to “
NO
” (normally open) position (door open).
• The words “
LOCK
” will flash on and off in the display while the lock motor is in
motion. When the door is locked, the word “
LOCK
” remain illuminated in the dis-
play.
• CAM - The ca, on the motor performs two functions:
1. Positions the lock in the door to prevent opening during clean operation.
2. Operates the lock switches which tell the control if the door is unlocked or locked
and ready for clean operation.
NOTE:
The door lock switch will be open when the latch is locking. Once locked, the
door switch will be closed.
