F MAGNETRON REMOVAL
1) Disconnect the leadwire from the magnetron.
2) Carefully remove the mounting screws holding the
magnetron and the waveguide.
3) Remove the magnetron ASSEMBLY until the tube
is clear from the waveguide.
NOTE:
1. When removing the magnetron, make sure its
dome does not hit any adjacent parts, or it may be
damaged.
2. When replacing the magnetron, be sure to install
the magnetron gasket in the correct position and be
sure that the gasket is in good condition.
3. After replacing the magnetron, check for microwave
leakage with a survey meter around the magnetron.
Microwave energy must be below the limit of 5
mW/cm
2 . (With a 275 ml. water load).
Make sure that gasket is rigidly attached to the
magnetron. To prevent microwave leakage, tighten
the mounting screws properly, making sure there is
no gap between the waveguide and the magnetron.
