Lock Motor Assembly
The lock motor assembly is located at the center
top of the oven front frame. The assembly
consists of the mounting plate, motor, micro
switches, cam and hook assembly.
To access the assembly:
1. Open the oven door.
2. Remove the 2 Torx screws securing the
mounting plate to the front frame and pull the
assembly out.
Door lock motor operation:
1. When the oven controls are set for CLEAN,
power is applied to the K3 relay coil, which
will energize the lock motor.
2. The lock motor drives the cam that closes
the latch CLOSED switch. As the lock hook
engages, the motor position switch will open,
supplying power to the K1 relay, which turns
the clean timer on.
3. At the end of the clean cycle, when the select
switch is pushed to off or another mode of
operation, the K4 relay will energize the lock
motor to drive the cam to the unlock position.
