Summary: Nesco bus maintenance (nesco) is recalling certain carrier gen v EM-1 evaporators installed as original equipment by nesco on various school and transit buses. The EM-1 evaporators contain a fuse holder in the motor assembly which due to time, temperature, and/or vibration may cause the fuse to loosen in the fuse holder, resulting in high resistance and arcing.
Consequence: If sufficient arcing occurs, the fuse holder may melt and potentially cause a fire.
Remedy: Nesco will notify owners and provide information on how to obtain the retrofit kit from carrier along with repair instructions. This service will be performed free of charge. Nesco has not provided a notification schedule. (see carrier's recall campaign 11E-003.) owners may contact carrier at 1-800-348-7440.

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Carrier EM-1 (model year not listed)

Has your Carrier been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Carrier dealer can also check your VIN. Recall repairs are free.
