The control display 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 lit in the display.
The cam on the motor performs two functions:
• Positions the lock hook in the door to prevent
opening during the CLEAN operation.
• 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.

Motorized Door Lock Circuit Information

The lock motor circuits and the lock switch circuit
control the locking and unlocking of the door.
The lock motor circuit applies voltage (120 VAC)
to the lock motor. This circuit is from L, through
the door switch, lock relay, and lock motor to
neutral.
For this circuit to be complete, the lock relay must
be energized by the ERC and the door must be
closed. An open oven door results in LOCK
DOOR flashing in the display after the control has
been programmed for clean and START has
been depressed.
