6 DISASSEMBLY AND PARTS REPLACEMENT
PROCEDURE
To prevent the water from invading the electric parts that can cause
a short circuit or electric shock:
1. Before repair or replacement of parts, ensure to remove the water
tank from microwave oven.
2. After removing the water tank, select the "drainage" function to
drain the water remaining in the water pipes and tubes into oven
cavity forcibly. (Operating method: keep pressing [Microwave with
Steam] pad for more than 2 seconds). Then wipe up the oven
cavity.
3. In case the Microwave Oven has no power, the technician should
have a dry cloth available in advance before disassembly. When
pulling out the water tube, elevate the front of the Microwave
Oven at least 1.5" to minimize the amount of water that leaks out.
Wipe up excess water throughly with the dry cloth.
After repair or replacement of parts, make sure that all the water pipes
and tubes are properly connected, otherwise the water might invade
the electric parts and will cause a short circuit or electric shock.
