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, heat
barrier, and mounting plate.
Access to this assembly, for single and upper
ovens, is behind the control panel. For lower
ovens, access is behind the trim cover between
the 2 ovens.
Motorized Door Lock Operation
The lock motor is energized when the control is
set for Clean and Clean Time selected. The relay
contact will close and complete the circuit that
supplies the voltage to the lock motor. (See table
for relay identification.)
