Magnet Clutch Operating Check

Reference: COMPRESSOR ASSEMBLY REMOVAL AND INSTALLATION 

Check the following items.

If any detects are found, repair or replace magnet clutch assembly.

• Inspect armature plate and rotor for signs of oil.
• Check clutch bearings for noise and grease leakage.
• Using an ohmmeter (2), measure resistance of stator coil between clutch lead wire (1) and compressor body.

  If measured resistance is out of specified value, replace coil.

  Specified resistance of magnet clutch 

  Approx. 3.2 - 4.3 Ω at 20 °C (68 °F)
