Check against the official notice below — it lists the full affected range.
StartTrans is recalling certain model year 2003-2007 MFSAB school activity buses equipped with Trans/Air TA73 evaporators. These buses have a defect in the blower speed control system where a short circuit in the low or medium speed circuit can cause excessive voltage to flow through a power resistor without triggering the fuse protection. This condition can cause the resistor to overheat, melt the plastic blower housing, and potentially ignite a fire.
To remedy this issue, Trans/Air will install a thermal shutdown device in series with the speed resistors at no charge to owners. The recall began on January 7, 2011. Affected consumers should contact Trans/Air Warranty and Service Center at 1-800-673-2446 to schedule the repair.

THIS WOULD CAUSE THE RESISTOR TEMPERATURE TO RISE TO A POINT WHERE IT WILL MELT AND POSSIBLY IGNITE THE PLASTIC BLOWER HOUSING TO WHICH IT IS MOUNTED. THE OVERHEATING CAN RESULT IN A FIRE.
TRANS/AIR, IN COOPERATION WITH STARTRANS, WILL INSTALL A THERMAL SHUTDOWN DEVICE IN SERIES WITH THE SPEED RESISTORS. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON JANUARY 7, 2011. OWNERS MAY CONTACT TRANS/AIR WARRANTY AND SERVICE CENTER AT 1-800-673-2446.
STARTRANS IS RECALLING CERTAIN MODEL YEAR 2003-2007 MFSAB SCHOOL ACTIVITY BUSES EQUIPPED WITH TRANS/AIR TA73 EVAPORATORS. THE EVAPORATOR UTILIZES A POWER RESISTOR TO REGULATE BLOWER SPEED. SHOULD A SHORT OCCUR IN THE "LOW OR MEDIUM SPEED" CIRCUIT WHILE THE BLOWER IS IN HIGH SPEED, THE SHORT WILL CAUSE THE SUPPLY VOLTAGE TO FEEDBACK THROUGH THE RESISTOR TO GROUND, NOT DRAWING ENOUGH CURRENT TO TRIP THE FUSE.
