Erc Failure Codes; Motorized Door Lock - GE JS760 Service Manual

ERC FAILURE CODES

The oven may stop operating but not give an F code on the display immediately.
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 displayed, 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.
if the door switch is in the "C" to "NC" position
(door open).
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 hook 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.
