DIAGNOSIS 6

PROCEDURE 4

Tip 1

When re-installing the air duct, move the wires out of the way so that they won’t be crushed by air duct.

Tip 2

After pushing the air duct into its position, there should be a sound of click. If no, redo it again.

Tip 3

Check to see if there is a wide gap between air duct and cabinet.
IF SO, install air duct again.

Tip 4

Ensure that latches are properly inserted into cavities.
