CAUTION
1.
Before repair or replacement of parts, ensure to take out the
water tank from microwave oven.
2.
After removing the water tank, select "drainage" function to drain
the water remaining in the water pipes and tubes into oven cavity
forcibly. (Operating method: keep pressing [Steam] pad for more
than 2 seconds). Then wipe up the oven cavity.
3.
The above procedure is to prevent the water from invading the
electric parts and resulting in short circuit even electric shock.
CAUTION
After repair or replacement of parts, make sure that all the water pipes
and tubes are properly connected, otherwise the water might invade
the electric parts and will cause short circuit even result in electric
shock.
4.1. Magnetron
1. Discharge the high voltage capacitor.
2. Remove 2 screws holding reinforce bracket A on oven
cavity.
3. Remove 2 screws holding reinforce bracket B on oven
cavity.
4. Remove 1 screw holding oven thermistor on cavity top
plate.
5. Release lead wire harness from locking tabs on inverter
bracket A.
6. Disconnect 2 high voltage lead wires from magnetron
filament terminals.
7. Remove 1 screw holding thermistor on magnetron.
8. Remove 1 screw holding air guide A on magnetron, then
remove air guide A.
9. Remove 2 screws holding air guide B on magnetron & on
base plate respectively, then remove air guide B.
10. Disconnect 2 lead wires from fan motor terminals.
11. Disconnect lead wires from noise filter (U) terminals.
12. Release locking tabs of reinforce bracket A hanging on both
sides of oven cavity, then withdraw the reinforce bracket A
outside slightly.
NOTE:
Pay attention to the sharp edges of reinforce
bracket A.
13. Hold the reinforce bracket A, then remove 4 screws holding
magnetron.
NOTE:
After replacement of the magnetron, tighten mounting
screws properly in an x pattern, making sure there is no
gap between the waveguide and the magnetron to
prevent microwave leakage.
CAUTION
When replacing the magnetron, be sure the antenna gasket is in
place.
CAUTION
When connecting 2 filament lead wires to the magnetron terminals,
be sure to connect the lead wires in the correct position. The lead wire
of high volatge transformer should be connected to “F terminal” and
the lead wire from high voltage capacitor should be connected to “FA
terminal”.
