Thomas Built Buses is recalling 64 2006-2011 Minotour, Saf-T-Liner Hdx, and Mvp-Ef non-school buses because a fuse in the Carrier GenV EM-1 evaporator unit can loosen in its holder, causing high resistance and arcing.

What's wrong?
The Carrier GenV EM-1 evaporator unit is part of the air conditioning system on affected 2006-2011 Thomas Built Buses Minotour, Saf-T-Liner Hdx, and Mvp-Ef buses. Its electrical circuit uses a fuse and fuse holder to protect the unit. The fuse is supposed to sit firmly in the holder so power flows through a clean, tight connection.
On these buses, time, temperature, and vibration loosen the fuse inside the holder. A loose fuse creates high resistance, which means electricity has to push through a poor connection. That poor connection leads to arcing, where electricity jumps across a small gap instead of flowing cleanly through the fuse contact.
The filing does not list a warning sign an owner or driver would notice first. There is no warning sign before failure.
