Are you an A. O. Smith Rep looking for older part number references?
Login to the ePortal to access the Item Inquiry tool.
A. O. Smith will require a serial number to provide an appropriate parts recommendation to any customer with a parts replacement need. If a serial number is not available, A. O. Smith is not liable for providing an appropriate replacement part.
Reps will continue to have access to cross reference older part numbers for Inventory Purposes ONLY via the Item Inquiry function within the ePortal (login required). A. O. Smith will not be liable if the Item Inquiry function is used to identify a replacement part for a customer where a serial number is not available.
