A defective air pressure switch in some Crown Home Heating Boilers can fail to shut down the burners allowing the boiler to emit excessive amounts of carbon monoxide, exposing consumers to CO poisoning hazard. Carbon monoxide poisoning is extremely dangerous because it is a deadly odorless gas. Carbon monoxide poisoning is the leading cause of poisoning death in the United States.
The models involved in the recall are Crown Boiler CWD series cast iron hot water boilers that use natural gas or liquid petroleum to heat water in home baseboard, floor or radiator heating systems. The boilers are red and gray, about 37 inches tall, about 23 inches deep and range from about 16 to 42 inches wide. The Crown Boiler logo is on the front of the boiler. Recalled boilers have model numbers that begin with CWD and were manufactured between May 1, 2005 and July 1, 2013.
