D. 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
(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.
