Change the Bulb

The bulb itself could be very hot when the dryer just
finishes its operation. So before changing the bulb,
be sure that the inside of the drum is cool down.

1. 

Open the door, put a hand into the drum and
grasp a bulb cover. 

2. 

With the bulb cover held by a hand, turn it to
the clockwise with a certain amount of the
force.

4. 

Remove the current bulb turning it to counter
clockwise direction. 
Be careful that it does not fall off.

5. 

Screw in the new bulb in the reverse
unscrewing direction.

6. 

With the bulb cover held by a hand, turn it to
the counterclockwise with a certain amount of
the force, until you listen to “click sound”

3. 

Seperate the bulb cover from the socket
housing.

Do not need any special tool for this work.
All steps can be done manually.

CAUTION

Power cord must be unplugged before this
work to avoid danger of electric shock.
