In June 2014, Trane voluntarily recalled 37 models of the Trane XB300 and American Standard Silver SI outdoor air conditioning systems, including units with model numbers beginning with 2TTM, 4A7M and 4TTM. Consumers can check the model number of their unit against the list provided by Trane on its website.
Consumers can also view the full product recall notice on the U.S. Consumer Product Safety Commission website by accessing the agency's main page, clicking on the Recalls link on the top menu, entering "Trane" in the Search Recalls and News Alerts form field on the right-hand side of the page and sorting the search results by clicking the Recent link. As of February 2015, the 2014 recall notice for the XB300 unit is at the top of the search results list.
The recalled outdoor air conditioning units are gray and have a black grated front. The units affected by the recall are either 23.5 inches wide or 28.48 inches wide and were sold through Trane and American Standard independent distributors and dealers from February 2010 to March 2014 at a price between $890 and $1,000.
Trane recalled the units because the ground screws used do not provide sufficient grounding, posing a shock hazard. Owners of this unit are advised to call Trane's toll-free customer service line or contact their installer or service dealer to schedule a free inspection and repair.
