Full Diagnosis
Overcurrent protection for single-phase of the compressor.
All Recorded Causes
Verify Before Replacing Parts
- Confirm the exact York model family and default context before acting on a generic code description.
- Verify current draw, overload status, and control signal before condemning the compressor or drive, given that the most likely cause listed above.
- Look for upstream conditions such as airflow or charge issues that may be pushing the compressor into protection, and check the next candidate on the list.
- After the correction, run the system long enough to confirm the default fault does not return under normal load.
