Lower Oven Door Lock Assembly
Note:
1. If only the lock motor and switch assembly and/
or cam has failed, it may not be necessary to
remove the door lock assembly from the range.
It is advisable to transfer these parts from a new
door lock assembly. Verify proper operation of
the lock assembly after transferring these parts.
2. The frame plate of the lower oven door lock
assembly is surrounded by insulation that will
block installation of the replacement door lock
assembly. Before extracting the lower oven door
lock assembly, it is necessary to create a path
for installing the replacement lock assembly by
inserting stiff cardboard or thin slats of wood
above and below the frame plate.
3. If insulation blocks installation of the lower oven
door lock assembly, it may be necessary to
remove the upper oven liner to replace the lower
oven door lock assembly. (See
Upper Oven Liner.)
