Check that the resistance shown in the graph is
almost satisfied when measuring the resistance
between the terminals under two or more different
temperature conditions.
NOTE: The temperature condition in checking
should be within the range shown.

Potentiometer check
When the resistance value between connector termi-
nals 3 and 5 is measured while checking the motor,
check that the resistance value changes gradually
within the standard value.
Standard value: 1.20 (MAX HOT)
− 4.80 (MAX
COOL) k
Ω
CHECK THE PHOTO SENSER
1. Connect the M.U.T.-III, and check the data list of
the photo sensor.
2. Check that the displayed value changes when
the photo sensor is covered with hands.
CHECK THE POWER TRANSISTOR
Check the thermal fuse.
AC309768
When the resistance between connector terminals 3
and 4 is measured, check that the resistance value is
within the standard value.
Standard value: Approximately 11 k
Ω
TRANSISTOR CHECK
Connect the (-) side clip of the tester to connector
terminal No.4 and the (+) side clip of the tester to ter-
minal No.5, and check that there is not a short or
open circuit in the transistor.

REMOVAL SERVICE POINTS
<<A>> FLEXIBLE SUCTION HOSE AND
FLEXIBLE DISCHARGE HOSE DISCON-
NECTION
CAUTION
Use the plug which is not breathable because
A/C compressor oil or receiver have high hygro-
scopicity.
Plug the removed nipple of the pipe, hose and
expansion valve to prevent the entry of dust and dirt.

1. Loosen the locking nut of the tensioner pulley
CAUTION
To reuse the drive belt, draw an arrow indicating
the rotating direction (clockwise) on the back of
the belt using chalk, etc.
2. Rotate the adjusting bolt to the anti-clockwise
direction (to the left), and remove the drive belt.
<<C>> A/C COMPRESSOR REMOVAL
Be careful not to spill the A/C compressor oil and
remove the A/C compressor.
INSTALLATION SERVICE POINT
>>A<< A/C COMPRESSOR INSTALLA-
TION
When installing the new A/C compressor, install the
A/C compressor after adjusting the oil volume as fol-
lows.
1. Measure the oil of A/C compressor removed.(X
cm

)
2. Drain the oil (Y cm

) given by the following
expression from a new A/C compressor, and then
install the A/C compressor.
