4. Remove the 4 screws holding magnetron.

5. Remove 2 screws holding thermal cutout.

6. Remove the air guide from magnetron and install it on the new

magnetron.

NOTE

To prevent microwave leakage, tighten mounting screws properly making sure there is no gap between
the waveguide and the magnetron.

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 with
blue connector should be connected to “FA
terminal” and white one should be connected to “F
terminal”. (See Figure)
