Carrier Air Conditioner Recall for Fire Risk in School Buses

Carrier is recalling specific air conditioner units installed in school and shuttle buses due to a fuse holder defect that may cause arcing, melting, and fire.

What this means for you

Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle component defect where the source explicitly states the fuse holder may melt and be accompanied by flame, smoke, and potential fire, meeting the criteria for significant injury/property-damage reports or structural vehicle defects.

Plain-English summary

Carrier Corporation is recalling certain Carrier GenV EM-1 evaporator units manufactured between January 1, 2006, and December 2010. These units contain a Delphi Pack-Con III fuse holder in an Allied Motion motor assembly. The affected units were sold as aftermarket equipment or installed as original equipment on certain school and shuttle buses. The recall covers units with part numbers 77-62112-XX and 77-62512-XX, with serial numbers ranging from KNT90890232 to NNE91230058.

The defect involves the fuse potentially loosening in the fuse holder due to time, temperature, and/or vibration. This loosening can result in high resistance and arcing. If sufficient arcing occurs, the fuse holder may melt, potentially accompanied by flame, smoke, and fire.

Carrier will notify bus manufacturers, authorized dealers, and known owners of record. The company is working with these parties to identify and notify owners of buses that may have the affected units. Carrier will provide a retrofit kit and repair instructions free of charge. The safety recall began on January 31, 2011. Owners may contact their vehicle manufacturer or Carrier at 1-800-793-4741.
