Fraser-Johnston serial number lookup

Identification guide: automatic serial-to-date or model decoding is not verified.

Spaces and dashes are accepted. Check O/0 and I/1, and keep any leading zeros.

Model and known context (optional)

Checks ENERGY STAR model records and searches manuals separately from the serial. Certification records do not establish this unit’s manufacture date.

Known product context (optional)

Choose a system only when it matches the product family and its documentation. A purchase year or a manual’s publication date does not establish a manufacturing date.
