Fan Motor Failure
Power supply turns off during operation. 'F61' is displayed on the FL.
(Occurs at a level of sound volume where the fan rotates).
The motor fan dislocated either by a fall during transportation or by
vibration, fails to rotate. Upon failure f the fan, the protector circuit
turns off power supply and, at the same time, indicates 'F61' on the FL.
The motor fan fixing ribs are changed in shape so that the fan will not
be dislocated easily.
From August 1996 production onward.
