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
airtight, moisture (condensation)-tight or light-tight.
Therefore, occasional appearance of moisture, light
or sensing of gentle warm air movement around
oven door is not abnormal and do not of themselves
indicate a leakage of microwave energy 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.
Remove door assembly, refer to "Door Replacement".
Replacement of door components are as follows:
CHOKE COVER
1. Place door assembly on a soft cloth with latches facing up.
Note: As the engaging part of choke cover and door panel are
provided at several places, do not force any particular part.
2. Insert an putty knife (thickness of about 0.5mm) into the gap
between the choke cover and corner portion of door panel
as shown Figure C-6 to free engaging parts.
3. Lift up choke cover.
4. Now choke cover is free from door panel.
NOTE: When carrying out any repair to the door, do not
bend or warp the slit choke (tabs on the door
panel assembly) to prevent microwave leakage.
