9.3. When parts must be replaced,
remove the power plug from
the outlet.
9.4. 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 short switch, the primary latch switch and short switch
must be replaced. It is also important to change the power
relay 1 (RY1) when the continuity test shows shorted con-
tacts.
1. This is mandatory. Refer to "adjustments and measure-
ments" for the location of these switches.
2. When replacing the fuse, confirm that it has the appropri-
ate 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.
9.5. 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 leak-
age.

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 tight-
ened.
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 proce-
dure for measuring microwave energy leakage).

IMPORTANT NOTICE
The following components have potentials above 250V
while the appliance is in operation.
• Magnetron
• High voltage transformer (Located on inverter (U))
• High voltage diodes (Located on inverter (U))
• High voltage capacitors (Located on inverter (U))
Pay special attention in these areas.
When the appliance is operated with the door hinges or
magnetron fixed incorrectly, the microwave leakage can
reach more than 5mW/cm
very important to check if the magnetron and the door
hinges are correctly fixed.
9.7. Sharp Edges
Caution
