F. AIR DUCT ASSEMBLY / REMOVAL
1)Disconnect the leadwire from lamp.
2)Remove the mounting screw to the magnetron.
G. MAGNETRON REMOVAL
1)Disconnect the leadwire from themagnetron.
2)Carefully remove the mounting screws holding the magnetron to the waveguide.
3)Remove the magnetron ASS’Y 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/cm2. (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.
