Step 2

Remove the mainboard cover.

Step 3

Check if terminal is pushed into final position.

Step 4

Check to see if terminal is full of foam. If so, use tweezers to remove foam. 

Step 5

Use multimeter to measure resistance value.

Step 6

Record the value.

Step 7

Test temperature on air duct close to sensor.

DIAGNOSIS 5
PROCEDURE 3

Tip 1

Before installing the airduct, please tie all wires
together.

Tip 2

Before installing the air duct, please fix cord of
fan well.

Tip 3
Insert left side first, then other side. Make sure
the cavity on the side is aligned with the ribs on
inner liner.

Tip 4

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