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.
Figure 29 Oven door latch
If the latch becomes stuck in the locked position, turning the unit off
and back on will open the latch if the cavity temperature <491°F. If
latch is stuck in a partially locked position, turn the mode and
temperature selectors to Self Clean, then turn them to Off.
If these measures fail, run a thin wire or wire coat hanger in between
the door and the front face of the oven. Figure 30 shows where to
position the wire between the latch hook (1) and the plunger (2). Slide
the wire to the left, pushing the latch hook left and releasing the latch.
