Inspection/Assembly Requirements-Following Compressor Failure

PROCEDURE
1. When an A/C compressor fails due to internal causes, clean the refrigerant system by flushing or filtering. This will remove any debris or contaminants that may be present and prevent damage to the replacement A/C compressor.

NOTE: The suction accumulator/drier and A/C evaporator core orifice cannot be cleaned and must be replaced.

2. Remove and discard the A/C evaporator core orifice.

NOTE: A dirty A/C evaporator core orifice or a condenser to evaporator tube containing black refrigerant oil and particles indicates that the A/C compressor has failed and must be replaced.

3. Remove the A/C compressor.

NOTE: Residual refrigerant oil in the A/C compressor must be drained and measured for proper system oil matching.

4. Remove the suction accumulator/drier.

NOTE: Residual refrigerant oil in the suction accumulator/drier must be drained and measured for proper oil system matching.

5. Clean the A/C evaporator core and the A/C condenser core by flushing.

NOTE: System flushing is the preferred method of cleaning. However, if flushing equipment is not available, system filtering may be performed as an alternative.

6. Install the replacement A/C compressor.
7. Install the replacement suction accumulator/drier.
8. Install the replacement A/C evaporator core orifice.
9. Properly oil match the system.
10. Evacuate and charge the system. Evacuation and Charging
