5.3. When parts must be replaced,
remove the power plug from
the outlet.
5.4. When the 10A 250V fuse is
blown due to the operation of
short switch:
1. This
is
mandatory.
Refer
to
"Adjustments
and
Measurement" for these switches.
2. When replacing the fuse, confirm that it has the appropriate
rating for these models.
3. When replacing faulty switches, be sure mounting tabs are
not bent, broken or otherwise deficient in their ability to hold
the switches.
5.5. Avoid inserting nails, wire, etc.
through any holes in the unit
during operation.
Never insert a wire, nail or any other metal object through the
lamp holes on the cavity or any other holes gaps, because such
objects may work as an antenna and cause microwave
leakage.

screws of the oven, etc. are neither loose nor missing.
Microwaves might leak if screws are not properly tightened.
2. Make sure that all electrical connections are tight before
inserting the plug into the wall outlet.
