DOOR LOCK MECHANISM

The purpose of the door lock mechanism is
to secure the door during the spin cycle.
When the door is shut, the wire loop on the
door engages the rotating gear in the door
lock mechanism (Figure 5-7) . When the
proper water level is reached and the pres-
sure switch is satisfied, 120 VAC is applied to
the wax motor. The piston in the wax motor
will extend, pushing the latch axle and sliding
gear from left to right. Teeth on the face of
the sliding gear will intermesh with the teeth
on the side of the rotating gear (normally takes
about 45-60 seconds). This interlocking of
teeth provides the locking action of the lock
mechanism.
At the end of the spin cycle, when tumbler
speed drops below 90 RPM, voltage is no
longer applied to the wax motor. The wax
motor will cool and relax the piston on the
wax motor. The latch axle and sliding gear
are then pulled from right to left, disengaging
the teeth of the sliding gear from the rotating
gear (normally takes 1 - 1½ minutes). This al-
lows the rotating gear to be in a position to
rotate if necessary, should the door be
opened.
