DOOR REPLACEMENT AND ADJUSTMENT

DOOR REPLACEMENT

1.Disconnect oven from power supply and remove outer case.

2.Holding the door, remove three (3) screws securing the upper door hinge to the oven cavity. The door assembly is nowfree from the oven cavity.

3.On re-installing new door assembly, secure the door assembly with the three (3) mounting screws to the oven cavity.

Make sure the door is parallel with the bottom line of the oven face plate and the latch heads pass through the latch holes correctly.

Note: After any service to the door, .-an approved microwave survey meter should be used to as-

sure compliance with proper microwave rediation standard.

(Refer to Microwave Measurement Procedure).

Note: If the Latch Heads Need Removal, “TORX T-20” or “LHXTIX LR-3” Type screwdriver should be used.

DOOR ADJUSTMENT

When removing and/or loosening hinges such as in the case of a door replacement, the following adjustment criteria are taken. Door is adjusted to meet the fol- lowing three conditions before tightening the binge screws.

I. Adjust door latch heads at a position where they smoothly catch the latch hooks through the latch holes. Refer to upper latch and lower latch switches adjustments.

2.Deviation of the door alignment from the horizontal line of cavity face to be less than 1 mm.

3.Door should be adjusted with its face depressed toward cavity face.

After hinge screws are tightened under foregoing con- ditions, recheck 1 and 2.

Note: The door on a microwave oven is designed to act as an electronic seal preventing the leakage of microwave energy from the oven cavity during

the cookcycle. This function does not require that the door be airtight, moisture condensation

tight or light-tigbt. Therefore, the occasional appearance of moisture, light or the sensing of gentle air movement around the oven door is not abnormal and do not of themselves, indicate a leakage of microwave energy from the 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.
