6.2 Door Latch/Motor Assembly

The motorized door latch (MDL) mechanism (120VAC 60Hz 4.3W)
has 2 switches - the door switch and the lock/unlock switch. The latch
will automatically lock when mode and temperature selectors are set
to Self Clean, and unlock when the oven cools to ~490°F. The latch
and motor are serviced as an assembly.
