are in the correct order
and their connections in
the foam are correct:
1. Set multimeter to
resistance gear;
2. Put detector into one
end of wires in PCB
area;
3. Put another detector

electrical tape.
CHECK AND TEST 4
Step 1
Set output of transformer
to DC 12V to test fan
from the terminal behind
the air duct.
Step 2

from the terminal behind
the air duct and see if fan
is running.
DIAGNOSIS 5
Note
PROCEDURE 4
Tip 1
Make sure the sealing sponges are in good condition.
Tip 2
When reinstalling the air duct, fasten the wires to avoid crushing with air duct.
