5.1.2.2 Door Lock Related Issues
The customer may not be initially aware of a failure of the door lock mechanism and the first
indication the customer will have is when the control display shows the flashing “DOOR” symbol or
an audible sound can be heard.
Under normal circumstances, the door lock is very reliable and has a life cycle of many thousands
of operations. However, customer misuse or incorrect assembly after service could give rise to
problems.
If the door is shut with great force, or the customer tries to open the door when it is locked closed,
it may in some circumstances be possible to break the door latch. To ensure that the oven will not
work in the self-clean” mode if the door is forced open, the door latch is designed in such a way
that the latch body will break at a defined break point before the latch head (figure 3).
Figure 3
The breaking of the latch body will ensure that the microwswitch will register a door open condition
and disable the self-clean” mode, instead of breaking the latch head and allowing the door to be
opened.
5.1.2.3 Door Latch Adjustments
Although no adjustment to the internal mechanism of the door lock is required, adjustment and
positioning of the whole assembly after the unit has been removed or tested is critical for its correct
functioning.
The following tests and adjustments should be made whenever a door lock mechanism is removed
or replaced.
5.1.2.3.1 Door Locking Adjustment
When removing the door lock mechanism, it is important to ensure that the shim washers are
retained and correctly positioned as shown (Figure 4).
