NOTE

: Before servicing, make

sure to discharge electric charge
remaining on the high voltage
capacitors or wait for more than 5
min.

Remove the back cover.

Disconnect all leadwires from the
magnetron.

Remove screws securing the duct-
MGT and duct-fan.

Remove the nut-

anges securing

the magnetron by using a box
wrench.

Take out the magnetron very
carefully.

NOTE1:

When removing the magnetron, make sure that its antenna does not hit any adjacent parts, or it may be

damaged.

NOTE2:

When replacing the magnetron, be sure to remount the magnetron gasket in the correct position and

make sure the gasket is in good condition.
