What's wrong?
The Carrier GenV EM-1 evaporator unit on 2006-2010 Startrans Mfsab school buses is part of the air conditioning system. Its electrical circuit uses a fuse and fuse holder to protect the unit by interrupting power when current rises above the circuit's limit.
On affected buses, time, temperature, and vibration loosen the fuse inside the holder. A loose fuse creates high resistance, which means electricity has a harder path through the connection. That resistance builds heat and leads to arcing, where current jumps across the poor connection instead of passing cleanly through the fuse.
There is no warning sign before failure. A driver or maintenance technician should treat unusual heat, burning odor, or visible damage near the evaporator unit fuse area as a service concern, but the recall does not identify a dependable early symptom.
Who's affected?
Covers the Mfsab across 5 model years, all tied to the air conditioner component.

What's the safety risk?
Electrical arcing at the fuse holder can melt the holder and lead to a vehicle fire.
