check the latch
interlock switch, the relay 7(on the control circuit
board) and the intertock monitor switch
according to "CHECKOUT
PROCEDURE
FOR
SWITCHES"
on page 6. and make sure to check
the microwave energy leakage according to "1.
ADJUSTMENT
PROCEDURES"
on page 1,
when the latch interlock switch, the relay 7 or the
intetlock monitor switch is adjusted or replaced.
If the latch interiock switch, the relay 7 and
the interlock monitor switch is defective,

interlock monitor switch. Then install a new 10 A
fuse.
If the latch interlock switch, the relay 7 and the
interlock monitor switch operate properly, determine
which of the followings is defective control circuit
board, blower motor, high voltage transformer, or
magnetmn.
If the high vottage diode is defective, replace not
only the high voltage diode but also fuse diode.
