IMPORTANT NOTICE [NEW H.V.]
1.The following components have potentials above
2000V while the appliance is operated.
* Magnetron
* High voltage transformer
* High voltage diode
* High voltage capacitor
Pay special attention to these components.
2.When the appliance is operated with the door
hinge or magnetron fixed incorrectly, the
microwave leakage can reach more than 5mW/cm
2
.
After repair or exchange, it is very important to
check if magnetron and the door hinge is correctly
fixed.
9. DISASSEMBLY AND PARTS REPLACEMENT
PROCEDURE
9.1. Magnetron
1. Discharge the high voltage capacitor.
2. Disconnect 2 connectors from fan motor B.
3. Remove 4 screws holing fan motor B (U) assembly.
4. Remove 3 screws which holding exhaust guide (U) onto oven.
5. Tilt exhaust guide (U).
6. Remove 1 screw holding air guide A and then remove air guide A.
7. Remove 2 high voltage lead wires from magnetron filament terminal.
8. Remove 4 screws holding magnetron.
NOTE:
After replacing the magnetron, tighten mounting screws properly
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.
9.2. Digital programmer circuit (DPC) and membrane key board.
NOTE:
Be sure to ground any static electric charge built up on your body
