CoolCut40air Fault Workflow Router

This router gives the fastest document order for the highest-value CoolCut40air complaints.

Complaint Routing

Incoming complaint	Open first	Then open	Then open if the complaint remains	Why this order works
complaint exists only in internal-air mode	CoolCut40air measurement card	CoolCut40air parts substitution card	CoolCut40air board opening map	the fastest path is mode split first, then air-package proving, then opening only if the complaint stays internal
both air paths move together or backward purge changes behavior	CoolCut40air measurement card	CoolCut40air board opening map	CoolCut40air job packet	dual-air behavior points directly at valve-control and contamination proof
poor cut with moisture or front-end suspicion	CoolCut40air parts substitution card	CoolCut40air guide	CoolCut40air job packet	torch-front-end and air-package faults still dominate this model
no start in both modes with healthy air	CoolCut40air measurement card	CoolCut40air board opening map	CoolCut40air guide	once both modes fail, the route shifts toward shared control or power branches

Official Parts Exit Paths

If the complaint proves external at any point in the router, use the official parts flow instead of continuing into board work.

SG55 tip 07Y2517005: use the official parts path above.

Stop Rules

Stop if the complaint exists in only one air mode.
Stop if drying the air package or changing the front-end stack removes the complaint.
Stop if backward purge or valve cleaning changes the symptom immediately.
Stop and move to the full guide if mode split, valve behavior, and output evidence still overlap after the first pass.
