Go to www.york.com and navigate to the “Support” or “Documentation” section.

Sites like Manualslib.com , Manuals.plus , or Archive.org often host York manuals. Search for “York YWM15L-AMlDA manual PDF” – ensure the file is complete (typically 15-30 pages).

Enter YWM15L-AMlDA into the model number search bar. Note: Sometimes the “l” is a capital “I” – try both YWM15L-AMlDA and YWM15I-AMIDA if the first search fails.
