DIAGNOSIS 5
PROCEDURE 3
Step 1
Disconnect the terminal of heater.
Step 2
Use screwdriver to remove the heat conductor (if any).
Step 3
Use 6mm cross-head driver to unscrew on left and right.
Step 4
Lift evaporator and heater 20mm, the bottom must be higher than the edge of the trough.
WARNING:
Be careful not to deform pipes in red square during steps 4.
Step 5

DIAGNOSIS 6
PROCEDURE 4
Tip 1
When reassembling the
air duct, move wires to
prevent crushing with
edge of air duct.
Tip 2
After pushing air duct into position, it should make a click sound. If no click is heard, do it again.
Tip 3
Check to see if there is a large gap between air duct and cabinet.
If there is, re-install air duct again.
