REMOVAL/INSTALLATION AND TROUBLESHOOTING FOR AIR CONDITIONING COMPRESSORS

REMOVAL/INSTALLATION AND
TROUBLESHOOTING FOR AIR
CONDITIONING COMPRESSORS





: General
The air conditioning compressor is driven by the vehicle engine .via a ribbed or V-ribbed belt. It compresses and transports the refrigerant in the system. There are different compressor designs available
How they work:
The refrigerant is sucked in as a gas under low pressure and low temperature from the evaporator; it is then compressed and forwarded to the condenser as a gas under high temperature and high pressure.






Effects of failure:
A damaged or failed compressor can manifest itself as follows:
Loss of sealing     -
Development of noise      -
Insufficient or no cooling performance       -
Fault code is stored (automatic air conditioning)      -
Caution!
Before installing a new compressor, you must check the oil quantity and
the viscosity according to the manufacturer's instructions!

There are a number of possible causes of failure:
-    Bearing damage caused by a defective tensioner or by wear    -
Loss of sealing of the compressor shaft or of the housing        -
Mechanical damage to the compressor housing        -
Contact (electrical connections)        -
Lack of refrigerant oil        -
Lack of refrigerant         -
Solids (e.g. swarf)         -
-       Humidity (corrosion etc.)  
Troubleshooting:

Function test and pressure measurement of the system:
      - Does the compressor switch on, is the connector plug
securely in place, is there voltage?
     - Check that the drive belt is positioned correctly, undamaged,
and that there is tension.
     - Check visually for loss of sealing.
     - Check that refrigerant tubes are securely in place.
      - Compare the pressures on the high and low pressure sides.
     - Read out the fault memory.

Attention must always be paid to the following:
The entire air conditioning system must be cleaned to 100 % and the
consumables must be replaced when the compressor is replaced.
