Service bulletin SER15020B

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

To remedy the situation in the field, Carrier Transicold is proactively replacing valve plate assemblies for those affected units. In SER15-020 Rev B, the affected population was amended based on updated information.
