NHTSA campaign 10V561000 · Part 573 safety recall report

Startrans Bus Corporation: Equipment

Startrans Bus Corporation reported this defect to federal regulators on Nov 15, 2010 and put the number of vehicles at risk at 53. The repair is free for as long as the recall stands.

The defect

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.

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 remedy

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.

What this page is, and what to do next

A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.

This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 10V561000.
