many factors which may cause microwave
Following mentioned may be the
causes of
microwave leakage:
(1) The door deformed, the hinge loosed or damaged that
caused the door can not

(2) The door pressing cover or the

(3) Obvious damage or uneven of the oven.
(4) There

(6) The crack of the door shielding net cover.
Before
check whether the above listed point
if not, can you start the microwave oven. Place a graduate of about 275ml water at the middle of the
tray, close the

there
places which the leakage exceeds the standard requirement, then repair them accordingly. If the

take down the cabinet, adjust the
screws of the hinge (up and Iow) as
to less the gap
between the door and the oven. Then measure again, the
leakage amount should be less than 1
Generally,
it should be controlled

with some
allowance.
If the leakage occurred at the right door crack, adjust the
screws which
the interlock holder and the hook. If the
leakage is the larger side at the right - above of the oven, then
adjust the upper screw as FIG.5 - 15. Loosen out the screw,
push the door close to the oven to hook the door hook with the
plastic
then tighten the Screw again. If the leakage is
larger at the right - below, then adjust the

tighten the screw again, and open and close the door repeatedly, to check whether the door can operate flexibly,

then adjust the door hook and
the switch holder repeatedly to
them to normal position, to put through the interlocks, to cut off the pilot
switch, to less the loose between the door and the oven, then measure the leakage with microwave measure
again.
If the leakage
exceeds standard requirement, then inspect whether the right oven is even or not, if not,
it. Then adjust the door and the oven to
their loose to the ultimate.
If there still exist microwave

If
the leakage is larger, the oven should be turned off and check
whether the four screws which fix the magnetron have been
loosed, if loosed,
them tightly with socket wrench. If the four
screws
fixed, then the magnetron should be taken down to
check the copper filament weaved washer of the magnetron has
