Service bulletin TSB240057

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.

This happens as generator set draws all the cooling air in and out of the bottom and the cool air intake and hot air discharge are very close to each other.
