REASON
When replacing the oven cavity in any of the above models, it is important that the
following notes are taken into consideration.
ACTION
1.  Safety first.  Ensure that the oven is disconnected from the mains supply and that
the high voltage capacitors have been discharged.
2.  When replacing the cavity, it is necessary to remove all parts from around the
cavity, as well as the base plate (item 2-1).  In most cases this operation can be
achieved without disconnecting the main wiring harness.
3. There are a number of cushions attached to the cavity and its peripheral
components that control the airflow around the oven and to minimise noise.  It is
possible that when replacing the cavity, that these cushions can become damaged.
Therefore it is recommended that they be replaced when the cavity is replaced.
It is important that cushion 4-12 is attached to the cavity before it is installed.
Cushion 4-12 is located on the bottom left hand edge of the cavity (as viewed from
the front).
A list of cushions to order when replacing the cavity is given on page 2 of this
Technical Bulletin.
4.  Fit the oven light screen (item 4-4), as this is not provided with the new cavity.
5.  Fit the insulation sheet (item 2-8) that is fitted underneath the top magnetron
temperature fuse.
