2002 GIRARDIN MB IV; 2001 GIRARDIN MB IV; 1999 GIRARDIN MB IV; 2000 GIRARDIN MB IV
Check against the official notice below — it lists the full affected range.
Corp. Micro Bird is recalling certain model year 1999 through 2002 Girardin MB IV transit buses built on Ford and GM cutaway chassis and equipped with a Trans/Air TA73 evaporator. If a short occurs in the "low or medium speed" circuit while the blower is in high speed, voltage can feed back through a power resistor without tripping the fuse. This causes the resistor to overheat to the point where it can melt and potentially ignite the plastic blower housing, creating a fire hazard.
Corp. Micro Bird, in cooperation with Trans/Air, will install a thermal shutdown device in series with the speed resistors to fix this problem at no cost. The recall began on January 11, 2011. Owners of affected buses should contact Trans/Air Warranty and Service Center at 1-800-673-2446.

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.
CORP. MICRO BIRD IN COOPERATION WITH TRANS/AIR 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 11, 2011. OWNERS MAY CONTACT TRANS/AIR WARRANTY AND SERVICE CENTER AT 1-800-673-2446.
CORP. MICRO BIRD IS RECALLING CERTAIN MODEL YEAR 1999 THROUGH 2002 GIRARDIN MB IV TRANSIT BUSES BUILT ON FORD AND GM CUTAWAY CHASSIS FROM AUGUST 2, 1999, THROUGH MAY 8, 2002, AND EQUIPPED WITH A TRANS/AIR TA73 EVAPORATOR. 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.
