CAUTION
Please use caution when unpacking, installing or
moving the unit, as some exposed edges may be
sharp to touch and cause injury if not handled with
care.
8. DISASSEMBLY AND PARTS REPLACEMENT
PROCEDURE
8.1. Magnetron
1. Discharge the high voltage capacitor.
2. Remove 2 screws holding magnetron thermal cutout.
3. Remove 1 screw holding air guide A.
4. Disconnect 2 high voltage lead wires from magnetron filament
terminals.
5. Remove 2 screws holding the 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.
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
voltage transformer should be connected to “F
terminal” and the lead wire from high voltage
capacitor should be connected to “FA terminal”.
