Replace the main switch unit (with
fuse).
*Check the fan motor unit at
same time.
There may be the possibility
of a motor problem
Continuity of Cord reel partition
unit
• Check that there is conduction
between the power plug and the
plug terminal using a tester.
• Check the state of connection of
the flag terminals to the plug ter-
minals.(Check that there is no
looseness.)
Also check for the presence/
