ACTUATOR REMOVAL/ADJUSTMENT

1.Follow the Microwave Drawer disassembly as previously stated

2.Open the drawer and keep it open.

3.To discharge the high voltage capacitor, wait for 60 seconds.

4.Locate either the right or left actuator and remove the 2 screws holding the actuator to the door support angles.

5.Relpace with the new actuator (Fig. A-3).

Actuator adjustment

6.It is very critical that proper adjustment is made to actuator.
