J.CAUTION FOR CUSTOMER ON OPENING AND
CLOSING DOOR
When the Microwave oven is in operation, should the
customer open the door slightly and close, the
breaker of the house will occasionally be cut off.
It is necessary to explain to the customer not to ex-
ercise such matter.
When the Door is opened slightly between 2 or 3mm
distance, primary interlock switch turn OFF, and
operation stops.
However door sensing switch will remain ON, and if
door is closed, primary interlock switch activates and
operation resumes immediately.
At such time microwave oven will start any time.
Therefore a big In-rush current flows, and thus breaker
will be cut off.
