Recall 10V618000: 2006–2007 Glaval Apollo, 2006–2008 Glaval Titan, 2006–2008 Glaval Universal +1 more

The problem

Glaval is recalling certain model year 2002, 2003, 2006, 2007, and 2008 ford e350/e450 universal, chevy/gmc 4500/5500 titan and freightliner mb-55 apollo transit buses manufactured from august 1999 through july 2007, 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.

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

Glaval 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 23, 2010. Owners may contact trans air warranty and service center at 1-800-673-2446.
