Measure the temperature of sensor.

 

NOTE


DIAGNOSIS 2

CHECK AND TEST 3

Step 1

Check to see if the terminal is full of foam.
IF SO, USE TWEEZERS TO CRUSH AND REMOVE FOAM.

Step 1

Connect A to B with metal wire.
Use multimeter to measure the connection from C and D.

DIAGNOSIS 3

Step 1

Check to see if the terminal is pushed into final position.
If not, push it to final position.

Note


PROCEDURE 2

Tip 1

When remounting air duct, move wires out of the way to avoid crushing them with air duct.

Tip 2

After pushing air duct into place, you should hear a clicking sound. If not, repeat 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

Check to make sure
the latches are inserted properly into the cavities.

Tip 5

First, insert top of cover plate into gap, then bend plate to insert the bottom. Lastly, push the middle into the slit.

CHECK AND TEST 4

Step 1

Measure resistance of sensor from terminal in PCB area.

Step 2

Take note of resistance value.

Step 3

Measure the temperature of sensor.

NOTE


DIAGNOSIS 4

PROCEDURE 3

Step 1

Push a 6mm sucker onto display and turn the knob to strengthen suction force.

Step 2

Attach strap to knob to facilitate pulling out display board.

Tips for proper installation of display:

Tip 1

After connecting terminal, please tape wires in place to prevent crushing by the cover.

Tip 2

After inserting display into cavity, press edge until you hear a clicking sound, this means the board is pushed properly into final position.

Please press all buttons on display board to make sure display functions properly.
