Signs It's Time to Replace
- Disc surface wear: deterioration of the working surface should be inspected
- Scoring: grooves or scoring on the disc surface should be evaluated
- Pitting: surface pitting can indicate deterioration
- Cracking or deformation: visible physical damage should be assessed
- Abnormal valve operation: changes in compressor valve operation should prompt inspection of the valve components
