All Recorded Causes
Verify Before Replacing Parts
- Confirm the exact York model family and default context before acting on a generic code description.
- Start with the exact model documentation and verify the full operating sequence before replacing parts, particularly around the most likely cause listed above.
- Use the listed causes as branches to confirm or eliminate with measurements, not assumptions — the next candidate on the list is a reasonable second branch.
- After the correction, run the system long enough to confirm the default fault does not return under normal load.
