1.Insert the upper and lower oven hinges into door hinge pins.

2.Insert the upper and lower oven hinges with door assembly into rectangular holes of oven cavity front plate.

3.Make sure that the door is parallel with oven face lines (left and upper side line) and door latch heads pass through the latch holes correctly.

4.Fasten upper and lower oven hinges firmly to oven cavity with two (2) screws on each hinge.

Note: After any service to the door;

(A)Make sure that interlock switches, stop switch and monitor switches are operating properly. (Refer to chapter "Test Procedures".).

(B)An approved microwave survey meter should be used to assure compliance with proper micro- wave radiation emission limitation standards.

DOOR ADJUSTMENT

When removing and/or loosening hinges such as in door replacement, the following adjustment criteria are taken. Door adjustment is performed with the door properly installed and closed and while the oven hinges are loose.

1.Loosen upper and lower oven hinges with phillips head screw driver.

2.Adjust the door by moving it vertically so that the top right hand corner of the door is in line with the top of the control panel frame assembly.

3.Tighten the upper and lower oven hinge screws.

After adjustment, make sure of the following:

1.Door latch heads smoothly catch the latch hook through the latch holes, and the latch head goes through the center of the latch hole.

2.Deviation of the door alignment from horizontal line of

cavity face plate is to be less than 1.0mm.

3.The door is positioned with its face depressed toward the cavity face plate.

4.Re-install outer case and check for microwave leakage around door with an approved microwave survey me- ter. (Refer to Microwave Measurement Procedure.)

Note: The door on a microwave oven is designed to act as an electronic seal preventing the leakage of microwave energy from oven cavity during cook cycle. This function does not require that door be air-tight, moisture (condensation)-tight or light- tight. Therefore, occasional appearance of mois- ture, light or sensing of gentle warm air movement around oven door is not abnormal and do not of themselves, indicate a leakage of microwave en- ergy from oven cavity. If such were the case, your oven could not be equipped with a vent, the very purpose of which is to exhaust the vapor-laden air from the oven cavity.
