Recall 10V-593: 2005–2008 Champion Challenger, 2007–2008 Champion International Defender
CHAMPION BUS, INC. recall for equipment, reported to NHTSA on Nov 18, 2010, covering about 107 vehicles.
The problem
Champion bus is recalling certain buses equipped with trans air ta 73 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.
The risk
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.
The fix
Champion bus 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 december 6, 2010. Owners may contact trans air warranty and service center at 1-800-673-2446.
