When Parts Must Be Replaced, Remove The Power Plug From The Outlet; When The 10A Fuse Is Blown Due To The Operation Of Short Switch; Avoid Inserting Nails, Wire, Etc. Through Any Holes In The Unit During Operation; Confirm After Repair - Panasonic NN-T559WB Service Manual

5.3 When parts must be replaced, remove
the power plug from the outlet.
5.4 When the 10A fuse is blown due to the
operation of short switch:
When the 10A 250V. fuse is blown due to the operation of
short switch, you must replace Primary latch switch and short
switch. Also replace power relay 1 (RY1) when the continuity
check reads shorted contacts (1-2).
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 or gaps, because
such objects may work as an antenna and cause microwave
leakage.
WARNING

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).

IMPORTANT NOTICE
1. The following components have potentials above 250V
while the appliance is operated.
• 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 on these areas.
When the appliance is operated with the door hinges or
magnetron is 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.
