Lock Assembly

A motorized door lock assembly is located above
each oven, and they are identical. The assembly
consists of a lock motor and switch assembly, cam,
lock hook, heat barrier, and mounting plate.
The lock motor is energized when the control is
set for clean and clean time selected. The K1 relay
contact will close and complete the circuit that
supplies the voltage to the lock motor.

Note: Display of control will fl ash "LOCK DOOR" if the
door switch is in the "C" to "NC" position (door open).
• The word "LOCKED DOOR" will fl ash on and off
in the display while the lock motor is in motion.
When the door is locked, the word "LOCKED DOOR"
remains 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.
Note: When the door is either being locked or
unlocked, both lock switches will be in the open
position.
The upper oven latch is controlled by the upper
oven relay board located on the back of the range.
The lower oven latch is controlled by the ERC/lower
oven control board located in the control panel
assembly.
