Erc Failure Codes; Motorized Door Lock - GE JCSS630 Quick Start Manual

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.
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.

Motorized Door Lock Operation :
Lock Switch
Door Switch
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.
