Check whether disconnected or not : See Fig. A
Check whether disconnected or not : if normal, the
resistance between two ends is 23.3~25.7Ω.
Check whether disconnected or not : See Fig. A
Measure the resistance of two ends of the sensor : refer
to the attached temp./resistance table
Measure the resistance of two ends of the sensor : refer
to the attached temp./resistance table
Check whether disconnected or not : See Fig. B
Check whether disconnected or not : if normal, the
resistance between two ends is 22.3~24.7Ω.
Shipped out Check the connection of two ends of fuse
temp.
Check whether disconnected or not : See Fig. B
Excessive Noise : Restraint/Failure of Fan Motor
Fan slipped out : MOTOR is operating, but there is
rotating sound.
Measure the resistance of two ends of the sensor : refer
to the attached temp./resistance table
