Control failure
This code typically points to
- Internal control-board fault
- Sometimes surfaced after repeated false lockouts
Next checks to confirm
- Verify line and low-voltage supply
- Verify no induced miswire/backfeed
- Replace control if fault persists
Escalation
Board-level escalation.
Reset behavior
Not documented in public snippets as a timed auto-reset; treat as persistent until corrected/reset.
