Key terminology
- Zero-voltage verify
- Confirm meter reads <1V across L1/L2 and L1/N before contacting any conductor.
- Service mode
- Diagnostic state that surfaces error history and exercises actuators.
- Root cause
- The single failure that explains every observed symptom — not a symptom itself.
- Functional test
- Documented end-to-end cycle proving the repair restored normal operation.
Field checklist
- ☐ Customer interview captured (symptom, frequency, recent changes).
- ☐ Power isolated and zero-voltage verified.
- ☐ Visual inspection: water, scorching, loose terminals, damaged harness.
- ☐ Live measurements recorded (resistance, continuity, supply voltage).
- ☐ Component replaced with OEM-equivalent part.
- ☐ Reassembled to factory torque/clearance spec.
- ☐ Functional test cycle completed and documented.
- ☐ Customer walkthrough and warranty paperwork delivered.
