WARNING
Never touch any circuit wiring with your hand or with an insulated
tool during operation.
2.3. Part replacement.
When any part or component is to be replaced, always ensure that the power cord is removed
from the wall outlet.
2.4. When the 10A fuse is blown due to the operation of the short
switch:
WARNING
When the 10A 250V fuse is blown due to the operation of the
interlock monitor switch, replace all of the components (primary
latch switch, door switch, short switch and power relay B (RY1)).
1. This is mandatory. Refer to “adjustments and measurements” for
the location of these switches.
2. When replacing the fuse, confirm that it has the appropriate rating
for these models.
3. When replacing faulty switches, be sure the mounting tabs are not
bent, broken or deficient in their ability to hold the switches.
2.5. 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
holes or gaps, because such objects may work as an antenna and cause microwave leakage.
2.6. Confirm after repair
1. After repair or replacement of parts, make sure that the 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.
3. Check for microwave energy leakage. (Refer to procedure for
measuring microwave energy leakage).
